AbstractLyme disease is an infection caused byBorrelia burgdorferi sensu lato, which is transmitted to humans through the bite of an infected Ixodes tick. The majority of patients recover without complications with antibiotic therapy. However, for a minority of patients, accompanying non-specific symptoms can persist for months following completion of therapy. The constellation of symptoms such as fatigue, cognitive dysfunction, and musculoskeletal pain that persist beyond 6 months and are associated with disability have been termed post-treatment Lyme disease syndrome (PTLDS), a subset of a broader term “chronic Lyme disease.” Chronic Lyme disease is a broad, vaguely defined term that is used to describe patients with non-specific symptoms that are attributed to a presumed persisten...

Conclusions: Operative management of pediatric patients with Lyme arthritis is associated with increased resource utilization and costs while being similarly efficacious to nonoperative management. As the US Lyme epidemic expands, improved diagnosis and management of acute undifferentiated arthritis may prevent unneeded operative intervention. Level of Evidence: Level III—retrospective cohort study. (Source: Journal of Pediatric Orthopaedics)

Authors: Didier G. Leibovici Helena Bylund Christer Björkman Nikolay Tokarevich Tomas Thierfelder Birgitta Evengård Shaun Quegan Some of the climate-sensitive infections (CSIs) affecting humans are zoonotic vector-borne diseases, such as Lyme borreliosis (BOR) and tick-borne encephalitis (TBE), mostly linked to various species of ticks as vectors. Due to climate change, the geographical distribution of tick species, their hosts, and the prevalence of pathogens are likely to change. A recent increase in human incidences of these CSIs in the Nordic regions might indicate an expansion of the range of ticks and hosts, with vegetation changes acting as potential predictors linked to habitat suitability. In this paper, we study districts in Fennoscandia and Russia where incid...

Cell Mol Neurobiol. 2021 Oct 18. doi: 10.1007/s10571-021-01154-8. Online ahead of print.ABSTRACTAlzheimer's disease (AD), the most frequently diagnosed dementia, is a senile neurodegenerative disorder characterized by amnesia and cognitive dysfunction. Unfortunately, there are still no successful strategies to prevent AD progression. Thus, the vast majority of research focuses on recognizing risk factors for developing and progressing this disease. Human spirochetes, fungi, Borrelia burgdorferi, Chlamydophila pneumoniae, Helicobacter pylori, and human herpes simplex virus type 1 (HSV-1) have all been implicated in the development and progression of AD. Identifying microRNAs (miRs) encoded by DNA viruses has indicated that viruses can be evolved to exploit RNA silencing to regulate host and...

Lyme borreliosis is a multisystemic disease caused by the pleomorphic bacteria of the Borrelia burgdorferi sensu lato complex. The exact mechanisms for the infection to progress into a prolonged sequelae of the disease are currently unknown, although immune evasion and persistence of the bacteria in the host are thought to be major contributors. The current study investigated B. burgdorferi infection processes in two human cell lines, both non-immune and non-phagocytic, to further understand the mechanisms of infection of this bacterium. By utilizing light, confocal, helium ion, and transmission electron microscopy, borrelial infection of chondrosarcoma (SW1353) and dermal fibroblast (BJ) cells were examined from an early 30-min time point to a late 9-days post-infection. Host cell invasio...

This study suggests that an adapted training-of-trainers is a feasible approach to raising tick and LD risk awareness among Qu ébec outdoor workers and public. Trained ambassadors have the potential of reaching a large portion of the population visiting or working in outdoor parks while also providing much-needed outreach regarding risk and prevention. Pushing this concept further to include other types of workers and juri sdictions may contribute to national LD surveillance efforts. (Source: PLoS One)

Radiologia (Engl Ed). 2021 Sep-Oct;63(5):425-435. doi: 10.1016/j.rxeng.2021.07.002.ABSTRACTInfections of the central nervous system caused by atypical bacteria are becoming more common. Borrelia burgdorferi and Rickettsia conorii are microorganisms transmitted by ticks; infection with these bacteria result in a wide spectrum of manifestations on imaging. In areas where these tick-borne microorganisms are endemic, including Spain, these infections must be included in the differential diagnosis of patients with a variety of systemic and neurologic symptoms. The clinical presentation of these infections is nonspecific, and CT is normally the initial imaging technique, although MRI is more sensitive to early changes. On MRI, these infections can manifest as small lesions in the deep supratento...

AbstractThe chemokine CXCL13 is used as complement to serology in the diagnostics of Lyme neuroborreliosis (LNB). We evaluated and compared the semi-quantitative, cassette-based ReaScan CXCL13 assay with the quantitative recomBead CXCL13 assay using a collection of 209 cerebrospinal fluid samples. The categorical agreement between results interpreted as negative, grey zone, and positive by the two methods was 87%. The diagnostic sensitivity was higher using the recomBead assay, whereas specificity was higher using ReaScan. Few manual steps, and a short turn-around time with no batching of samples makes the ReaScan CXCL13 assay an attractive complement to serology in the diagnostics of LNB.

Mil Med. 2021 Oct 6:usab420. doi: 10.1093/milmed/usab420. Online ahead of print.ABSTRACTLyme disease is a vector-borne infection that can affect multiple different organ systems. Lyme carditis represents one of these sequelae and is defined by acute onset of high-grade atrioventricular block in the presence of laboratory-confirmed infection. Current guidelines recommend patients with Lyme carditis be admitted for close cardiac monitoring and intravenous antibiotics therapy. Our case illustrates an active duty male who was initially diagnosed with Lyme disease after initially reporting symptoms including headache, fever, eye pain, and rash, with subsequent development of exercise intolerance 6 weeks later. An electrocardiogram (ECG) obtained at that time was misinterpreted as first-degree h...

FINDINGSA UCLA study suggests that many physicians may not have the knowledge or training to properly recognize how Lyme disease appears on the skin of Black patients. The disease, caused by the tick-borne Borrelia bacterium, generally begins with a bull ’s-eye–shaped rash on the skin, along with fever, headache, chills and muscle pain; if not diagnosed promptly and treated with antibiotics, it can lead to more severe and long-lasting symptoms.UCLA ’s Dr. Dan Ly found that approximately 1 in 3 Black patients who were newly diagnosed with Lyme disease already had related neurological complications such as meningitis, neuropathy and cranial neuritis — an indication that the disease may not have been properly diagnosed in its earlier stages. Less than 1 in 10 newly diagnosed white pat...

Assembly of the bacterial flagellar rod, hook, and filament requires penetration through the peptidoglycan (PG) sacculus and outer membrane. In most β- and γ-proteobacteria, the protein FlgJ has two functional domains that enable PG hydrolyzing activity to create pores, facilitating proper assembly of the flagellar rod. However, two distinct proteins performing the same functions as the dual-domain FlgJ are proposed in δ- and ε-proteobacteria as well as spirochetes. The Lyme disease spirochete Borrelia burgdorferi genome possesses a FlgJ and a PG lytic SLT enzyme protein homolog (BB0259). FlgJ in B. burgdorferi is crucial for flagellar hook and filament assembly but not for the proper rod assembly reported in other bacteria. However, BB0259 has never been characterized. Here, we use cr...

When health experts talk about the remarkable efficacy of COVID-19 vaccines, they typically point to their ability to prevent severe disease and death. Fully vaccinated people can still get “breakthrough” infections from the virus that causes COVID-19—but compared to an unvaccinated person, they’re more than 10 times less likely to be hospitalized or die from their illness, according to U.S. Centers for Disease Control and Prevention (CDC) research. Officials often point to these impressive figures as evidence that we can tame COVID-19 into a mostly mild illness that behaves like a routine cold or flu, and thus with which we can coexist. After all, the vaccines were not designed to quash viral spread entirely; they were designed to defang the virus by preventing its...

The objective of this study was to estimate the speed and direction of human Lyme disease emergence in Québec and to identify spatiotemporal risk patterns. A surface trend analysis was conducted to estimate the speed and direction of its emergence based upon the first detected case of Lyme disease in each municipality in Québec since 2004. A cluster analysis was also conducted to identify at-risk regions across space and time. These analyses were reproduced for the date of disease onset and date of notification for each case of Lyme disease. It was estimated that Lyme disease is spreading northward in Québec at a speed varying between 18 and 32 km/year according to the date of notification and the date of disease onset, respectively. A significantly high risk of disease was found in sev...

AbstractFor diagnosis of neuroborreliosis, calculation of the antibody index, based on Euroimmun Anti-Borrelia plus VlsE ELISA was compared to Virotech Borrelia Europe plus TpN17 immunoblot-based detection ofBorrelia-specific intrathecal antibody production. CXCL13 results in cerebrospinal fluid were used to evaluate discordant results. A total of 64 serum/CSF pairs were analysed. Patients were classified according to European Federation of Neurological Societies criteria incorporating Virotech results. For the Euroimmun assay, a sensitivity of 100% and specificity of 94% was found. Agreement between the both tests was almost perfect (κ 0.81). Both methods are appropriate for the detection ofBorrelia-specific intrathecal antibody production. (Source: European Journal of Clinical Microbiol...

This article reviews the symptomatology, diagnosis, and treatment of neuroborreliosis. RECENT FINDINGS The most recent guidelines for the diagnosis and treatment of Lyme disease were published in 2020 by the Infectious Diseases Society of America, the American Academy of Neurology, and the American College of Rheumatology. SUMMARY The most common neurologic complications of Lyme disease are cranial neuritis (most often a unilateral or bilateral facial nerve palsy), meningitis, and radiculoneuritis/mononeuropathy multiplex. Testing for Lyme disease begins with an enzyme-linked immunosorbent assay (ELISA). If the ELISA is positive or borderline, Western blots should be performed for both IgM and IgG antibodies. As a general rule, in infectious diseases, an IgM antibody response...

People in Denmark diagnosed with Lyme disease in a hospital went on to have 28% higher rates of mental disorders and were twice as likely to have attempted suicide, compared with those without the diagnosis, according to astudy published Wednesday inAJP in Advance. Having more than one episode of Lyme disease was associated with a higher rate of mental disorders, affective disorders, and suicide attempts.According to theCDC, nearly half a million people a year in the United States are treated for Lyme disease (also known as Lyme borreliosis), the most common vector-borne disease, and the areas where Lyme disease is common are expanding. Several studies have pointed to a connection between Lyme disease and psychiatric manifestations in people with untreated infection as well as months to ye...

CONCLUSIONS: Individuals diagnosed with Lyme borreliosis in the hospital setting had an increased risk of mental disorders, affective disorders, suicide attempts, and suicide. Although the absolute population risk is low, clinicians should be aware of potential psychiatric sequelae of this global disease.PMID:34315282 | DOI:10.1176/appi.ajp.2021.20091347 (Source: The American Journal of Psychiatry)

The high polymorphism of Major Histocompatibility Complex (MHC) genes is generally considered to be a result of pathogen-mediated balancing selection. Such selection may operate in the form of heterozygote advantage, and/or through specific MHC allele–pathogen interactions. Specific MHC allele–pathogen interactions may promote polymorphism via negative frequency-dependent selection (NFDS), or selection that varies in time and/or space because of variability in the composition of the pathogen community (fluctuating selection; FS). In addition, divergent allele advantage (DAA) may act on top of these forms of balancing selection, explaining the high sequence divergence between MHC alleles. DAA has primarily been thought of as an extension of heterozygote advantage. However, DAA could als...

In current study, we performed an integrative approach to predict antigenic sites in SARS-CoV-2 spike receptor binding domain and found nine potential antigenic sites. The predicted antigenic sites were then assessed for possible molecular similarity with other known antigens in different organisms. Out of nine sites, seven sites showed molecular similarity with 54 antigenic determinants found in twelve pathogenic bacterial species (Mycobacterium tuberculosis, Mycobacterium leprae, Bacillus anthracis, Borrelia burgdorferi, Clostridium perfringens, Clostridium tetani, Helicobacte...

Availability of highly parallelized immunoassays has renewed interest in the discovery of serology biomarkers for infectious diseases. Protein and peptide microarrays now provide a rapid, high-throughput platform for immunological testing and validation of potential antigens and B-cell epitopes. However, there is still a need for tools to prioritize and select relevant probes when designing these arrays. In this work we describe a computational method called APRANK (Antigenic Protein and Peptide Ranker) which integrates multiple molecular features to prioritize potentially antigenic proteins and peptides in a given pathogen proteome. These features include subcellular localization, presence of repetitive motifs, natively disordered regions, secondary structure, transmembrane spans and pred...

We present new evidence for maternal transfer of oral vaccine induced neutralizing anti-OspA IgG antibodies to mouse pups mainly through ingestion of colostrum. We found a strong statistical correlation of antibody transfer between mothers that produced the most robust IgG response to OspA and their respective pups. OspA-specific antibody was detected as early as 24 h after birth and protective levels of antibodies lasted until ~5 weeks of age in the majority of pups but persisted in some mice until 9 weeks. This was further supported by detection of neutralizing antibodies in serum of all pups at 2-3 weeks after birth and in some offspring adult mice at 9 weeks of age. A clear association was found between robust antibody responses in mothers and the length of time antibody persisted in t...

At my animal hospital in upstate New York, an epicenter of the U.S. tick epidemic, my dog Fawn lets out a whimper as the veterinarian injects her with her annual Lyme disease shot. I roll my eyes. She doesn’t know how good she has it. The injection means that if a tick bites her (and in rural New York, a tick always does), the creepy crawly will feast on dog blood that’s been supercharged with a Lyme bacteria-killing substance, and Lyme disease won’t be transmitted to Fawn. I wish I could be shot up with that superpower. Currently, there is no human vaccine for Lyme disease—even though more than two decades ago, people could get a safe and effective preventative shot similar to Fawn’s.

Disrupting transmission of Borrelia burgdorferi sensu lato complex (B. burgdorferi) from infected ticks to humans is one strategy to prevent the significant morbidity from Lyme disease. We have previously shown that an anti-OspA human mAb, 2217, prevents transmission of B. burgdorferi from infected ticks in animal models. Maintenance of a protective plasma concentration of a human mAb for tick season presents a significant challenge for a preexposure prophylaxis strategy. Here, we describe the optimization of mAb 2217 by amino acid substitutions (2217LS: M428L and N434S) in the Fc domain. The LS mutation led to a 2-fold increase in half-life in cynomolgus monkeys. In a rhesus macaque model, 2217LS protected animals from tick transmission of spirochetes at a dose of 3 mg/kg. Crystallographi...

This study investigates cyaB expression along with its influence on borrelial virulence regulation and mammalian infectivity. Expression of cyaB was specifically induced with co-incubation of mammalian host cells that was not observed with cultivated tick cells suggesting that cyaB expression is influenced by cellular factor(s) unique to mammalian cell lines. The 3′ end of cyaB also encodes a small RNA, SR0623, in the same orientation that overlaps with bb0722. The differential processing of cyaB and SR0623 transcripts may alter the ability to influence function in the form of virulence determinant regulation and infectivity. Two independent cyaB deletion B31 strains were generated in 5A4-NP1 and ML23 backgrounds and complemented with the cyaB ORF alone that truncates SR0623, cyaB with i...

Phys Ther. 2021 May 17:pzab128. doi: 10.1093/ptj/pzab128. Online ahead of print.ABSTRACTThe most commonly reported vector-borne and tick-borne disease (TBD) in the United States is Lyme disease. Individuals with Lyme disease may present with a wide array of symptoms with resultant musculoskeletal, neurological, and cardiac manifestations that may cause them to seek physical therapist services. The symptoms may develop insidiously and with a variable presentation among individuals. Many persons with Lyme disease do not recall a tick bite or present with an erythema migrans rash, which is considered pathognomonic for the disease. Even if they do, they may fail to associate either with their symptoms, making the diagnosis elusive. It is important to diagnose patients early in the disease proc...

Conclusions: The changes in kinematics and dynamics of HMEC-1 cells exposed to Borrelia burgdorferi (MOI= 200 bacteria/cell) at early times post-infection are associated with changes in innate immune signaing of the host cells. At later times post-infection were these changes in gene expression are not present anymore, host cell kinematics and dynamics are identical between infected and uninfected cells. Thus it is possible that innate immune singaling might be underlying the changes that host cells undergo in their motion and traction forces at early infection. (Source: GEO: Gene Expression Omnibus)

Relapsing fever (RF), caused by spirochetes of the genus Borrelia, is a globally distributed, vector-borne disease with high prevalence in developing countries. To date, signaling pathways required for infection and virulence of RF Borrelia spirochetes are unknown. Cyclic di-AMP (c-di-AMP), synthesized by diadenylate cyclases (DACs), is a second messenger predominantly found in Gram-positive organisms that is linked to virulence and essential physiological processes. Although Borrelia is Gram-negative, it encodes one DAC (CdaA), and its importance remains undefined. To investigate the contribution of c-di-AMP signaling in the RF bacterium Borrelia turicatae, a cdaA mutant was generated. The mutant was significantly attenuated during murine infection, and genetic complementation reversed th...

Print 2021 May 19.ABSTRACTSUMMARYThe Borrelia spp. are tick-borne pathogenic spirochetes that include the agents of Lyme disease and relapsing fever. As part of their life cycle, the spirochetes traffic between the tick vector and the vertebrate host, which requires significant physiological changes and remodeling of their outer membranes and proteome. This crucial proteome resculpting is carried out by a diverse set of proteases, adaptor proteins, and related chaperones. Despite its small genome, Borrelia burgdorferi has dedicated a large percentage of its genome to proteolysis, including a full complement of ATP-dependent proteases. Energy-driven proteolysis appears to be an important physiological feature o...

Purpose of review Neurosyphilis (NS) and Lyme neuroborreliosis (LNB) are spirochetal diseases with distinct clinical manifestations. The diagnosis of NS remains challenging due to imperfect diagnostic criteria and testing modalities. With LNB, misconceptions about diagnosis and treatment lead to considerable morbidity and drug related adverse effects. Recent findings Although studies continue investigating alternate approaches and new diagnostic tests for NS, few data exist to change current approaches to diagnosis, management or follow up. In the diagnosis of LNB, the chemokine CXCL13 shows promising diagnostic accuracy. A systematic review discourages the use of cell-based assays when investigating Lyme disease. Clinical studies show no benefit from extended antibiotic treatme...

AbstractWe assessed the prevalence of Lyme neuroborreliosis in children with acute facial nerve palsy in a Lyme-endemic region and patient characteristics associated with this. All children visiting one of three participating hospitals between January 2010 and December 2016 were included in the study. Of 104 children referred to the hospital with facial nerve palsy, 43% had Lyme neuroborreliosis and 57% idiopathic facial palsy. Characteristics significantly associated with Lyme neuroborreliosis were headache (55% versus 18%), meningeal irritation (21% versus 5%), presentation in summer months (69% versus 37%), and a previous tick bite (33% versus 7%).

In this report, we describe the use of multiple molecular detection techniques for this pathogen and its application to a case study of a Lyme disease patient. The patient had a history of Lyme disease, was treated with antibiotics, and years later developed chronic symptoms including dementia. The patient's pathology and clinical case description was consistent with Lewy body dementia. B. burgdorferi was identified by PCR in several CNS tissues and by immunofluorescent staining in the spinal cord. These studies offer proof of the principle that persistent infection with the Lyme disease spirochete may have lingering consequences on the CNS. (Source: Frontiers in Neurology)

ConclusionIn this exploratory cohort study, we found lower or similar concentrations of circulating cytokines in blood from patients with Lyme neuroborreliosis at time of diagnosis compared with references. The stimulated cytokine release in blood from patients with Lyme neuroborreliosis was in general slightly lower than in the references. Specific patterns of low IL-12 and IFN-γ indicated low Th1-response and low concentrations of IL-17A did not support a strong Th17 response. Our results suggest that patients with Lyme neuroborreliosis elicit a slightly suppressed or impaired immune response for the investigated stimulations, however, whether the response normalizes remains unanswered.

Conclusion Approximately 10% of all cases of extrapulmonary TB have osteoarticular involvement. Dactylitis is a variant of tuberculous osteomyelitis affecting the long bones of the hands and feet. It occurs mainly in young children; however adults may be affected also. The first manifestation is usually pai nless swelling of the diaphysis of the affected bone followed by trophic changes in the skin. The radiographic changes are known as spina ventosa, because of the ballooned out appearance of the bone, although this was not seen in our case. Fibrous dysplasia, congenital syphilis, sarcoidosis and sick le cell anaemia may induce similar radiographic changes in the metaphysis of long bones of hands and feet, but do not cause soft tissue swelling or periosteal reaction.

Early stage Lyme-associated erythema migrans most commonly manifests with a “targetoid” appearance. However, several erythema migrans variants have been reported, which may result in misidentification and delayed diagnosis and treatment. This case series presents a rare variant of bullous erythema migrans. Case 1: A 54-year-old woman presented with a worsening lesion on her leg. She reported a sudden onset of stinging in the area while walking outdoors. A darkening vesiculobullous rash appeared soon after. (Source: Journal of Investigative Dermatology)

Lyme disease is a multi-system disease caused by Borrelia burgdorferi (Bb) bacterium, which typically affects the skin, heart, nervous, and musculoskeletal system. Most individuals characteristically develop erythema migrans after exposure to Lyme disease, which presents differently in Skin of Color populations. Previous studies have noted there is an increased need for racial diversity in Lyme-related dermatological education in order to provide patients with timely care. We sought to compare the baseline characteristics and inpatient financial burden of Lyme disease between White and Non-White patients. (Source: Journal of Investigative Dermatology)

Lyme disease is the most common vector-borne illness in Switzerland and Lyme arthritis the most prevalent manifestation of late-stage Lyme disease. It presents as a monoarthitis or oligoarthritis in large joints, often involving the knee. Such a clinical presentation, together with positive Lyme serologies or polymerase chain reactions from synovial fluid/tissue, is considered diagnostic. If there is no tick bite or erythema migrans in the patient's history the diagnosis can be challenging due to the many differential diagnoses. The initial treatment is a prolonged course of oral antibiotics.PMID:33849286 | DOI:10.1024/1661-8157/a003665 (Source: ...

Online ahead of print.ABSTRACTCurrently there is no human vaccine against Lyme borreliosis, and most research focuses on recombinant protein vaccines, as such a vaccine has been proven to be successful in the past. The expression of recombinant antigens in meningococcal Outer Membrane Vesicles (OMVs), with the OMV functioning both as adjuvant and delivery vehicle, greatly enhances their potential. Immunization studies in mice have shown that OMV-based vaccines can protect against various pathogens and an OMV-based meningococcal vaccine is approved and available for human use. Because of its surface localization in Borrelia and the detailed knowledge regarding its immunogenicity and structure, OspA was chosen as...

In this study, we selected four representative tick species which have different regional distribution foci in mainland China. i.e., Dermacentor marginatus, Dermacentor silvarum, Haemaphysalis longicornis and Ixodes granulatus. We used the MaxEnt model to identify the key environmental factors of tick occurrence and map their potential distributions in 2050 under four combined climate and socioeconomic scenarios (i.e., SSP1-RCP2.6, SSP2-RCP4.5, SSP3-RCP7.0 and SSP5-RCP8.5). We found that the extent of the urban fabric, cropland and forest, temperature annual range and precipitation of the driest month were the main determinants of the potential distributions of the four tick species. Under the combined scenarios, with climate warming, the potential distributions of ticks shifted to further...

In this study, we employed microfluidic tools to probe the interaction between human neutrophils and Bb and measured the activation of human neutrophils in blood samples from patients. We found that neutrophils migrate vigorously toward Bb in the presence of serum, and this process was complement-dependent. Preventing complement factor 5 cleavage or blocking complement receptors decreased neutrophil ’s ability to interact with Bb. We also found that spiking Bb directly into the blood from healthy donors induced spontaneous neutrophil motility. This response to Bb was also complement-dependent. Preventing complement factor 5 cleavage decreased spontaneous neutrophil motility in Bb-spiked blood . Moreover, we found that neutrophils in blood samples from acute LD patients displayed spontane...

The successful treatment of Lyme disease (LD) is contingent on accurate diagnosis. However, current laboratory detection assays lack sensitivity in the early stages of the disease. Because delayed diagnosis of LD incurs high healthcare costs and great suffering, new highly sensitive tests are in need. To overcome these challenges, we developed an internally controlled quantitative PCR (Ter-qPCR) that targets the multicopy terminase large subunit (terL) gene encoded by prophages that are only found in LD-causing bacteria. The terL protein helps phages pack their DNA. Strikingly, the detection limit of the Ter-qPCR was analytically estimated to be 22 copies and one bacterial cell in bacteria spiked blood. Furthermore, significant quantitative differences was observed in terms of the amount o...

Although widely prevalent, Lyme disease is still under-diagnosed and misunderstood. Here we followed 73 acute Lyme disease patients and uninfected controls over a period of a year. At each visit, RNA-sequencing was applied to profile patients' peripheral blood mononuclear cells in addition to extensive clinical phenotyping. Based on the projection of the RNA-seq data into lower dimensions, we observe that the cases are separated from controls, and almost all cases never return to cluster with the controls over time. Enrichment analysis of the differentially expressed genes between clusters identifies up-regulation of immune response genes. This observation is also supported by deconvolution analysis to identify the changes in cell type composition due to Lyme disease infection. Importantly...

Lyme borreliosis is a multi-organ disease primarily transmitted by ticks. The condition is endemic in different parts of Europe and North America, and is caused by the spirochetes Borrelia burgdorferi sensu stricto, Borrelia garinii and Borrelia afzelii. Nervous system manifestations termed Lyme neuroborreliosis (LNB) are seen in 10 –15% of all borrelia infections in adults. The most common manifestations are meningoradiculitis and cranial neuritis (Summer and Rupprecht, 2019). Rarer neurological complications include brain and spinal cord involvement, cerebral vasculitis and peripheral neuropathies (Moser, Bubel et al. (Source: International Journal of Infectious Diseases)

Blood-feeding arthropods are considered an enormous public health threat. They are vectors of a plethora of infectious agents that cause potentially fatal diseases like Malaria, Dengue fever, Leishmaniasis, and Lyme disease. These vectors shine due to their own physiological idiosyncrasies, but one biological aspect brings them all together: the requirement of blood intake for development and reproduction. It is through blood-feeding that they acquire pathogens and during blood digestion that they summon a collection of multisystemic events critical for vector competence. The literature is focused on how classical immune pathways (Toll, IMD, and JAK/Stat) are elicited throughout the course of vector infection. Still, they are not the sole determinants of host permissiveness. The dramatic c...

Tick saliva is a rich source of pharmacologically and immunologically active molecules. These salivary components are indispensable for successful blood feeding on vertebrate hosts and are believed to facilitate the transmission of tick-borne pathogens. Here we present the functional and structural characterization of Iripin-3, a protein expressed in the salivary glands of the tick Ixodes ricinus, a European vector of tick-borne encephalitis and Lyme disease. Belonging to the serpin superfamily of protease inhibitors, Iripin-3 strongly inhibited the proteolytic activity of serine proteases kallikrein and matriptase. In an in vitro setup, Iripin-3 was capable of modulating the adaptive immune response as evidenced by reduced survival of mouse splenocytes, impaired proliferation of CD4+ T ly...

In contrast, DNA tattoo vaccines against tick proteins TSLPI, Salp15, tHRF, and Tix-5 induced low to moderate IgG titers and did not provide protection. Therefore, DNA tattoo vaccination does not seem a suitable vaccine strategy to identify, or screen for, tick antigens for anti-tick vaccines. However, DNA tattoo vaccination is a straightforward and effective vaccination platform to assess novel B. burgdorferi sl antigen candidates in a relevant tick challenge model.

Authors: Pham Underwood Oliva Chávez Ticks are obligate hematophagous parasites and are important vectors of a wide variety of pathogens. These pathogens include spirochetes in the genus Borrelia that cause Lyme disease, rickettsial pathogens, and tick-borne encephalitis virus, among others. Due to their prolonged feeding period of up to two weeks, hard ticks must counteract vertebrate host defense reactions in order to survive and reproduce. To overcome host defense mechanisms, ticks have evolved a large number of pharmacologically active molecules that are secreted in their saliva, which inhibits or modulates host immune defenses and wound healing responses upon injection into the bite site. These bioactive molecules in tick saliva can create a privileged environment in the...

Lyme borreliosis is an emerging tick-borne disease caused by spirochetes Borrelia burgdorferi sensu lato. In Europe, Lyme borreliosis is predominantly caused by Borrelia afzelii and transmitted by Ixodes ricinus. Although Borrelia behavior throughout tick development is quite well documented, specific molecular interactions between Borrelia and the tick have not been satisfactorily examined. Here, we present the first transcriptomic study focused on the expression of tick midgut genes regulated by Borrelia. By using massive analysis of cDNA ends (MACE), we searched for tick transcripts expressed differentially in the midgut of unfed, 24h-fed, and fully fed I. ricinus nymphs infected with B. afzelii. In total, we identified 553 upregulated and 530 downregulated tick genes and demonstrated ...

Authors: Branda JA, Steere AC Abstract SUMMARYLyme borreliosis is caused by a growing list of related, yet distinct, spirochetes with complex biology and sophisticated immune evasion mechanisms. It may result in a range of clinical manifestations involving different organ systems, and can lead to persistent sequelae in a subset of cases. The pathogenesis of Lyme borreliosis is incompletely understood, and laboratory diagnosis, the focus of this review, requires considerable understanding to interpret the results correctly. Direct detection of the infectious agent is usually not possible or practical, necessitating a continued reliance on serologic testing. Still, some important advances have been made in the area of diagnostics, and there are many promising ideas for future assay d...

Arsnoe, Richard Gerhold, Seungeun Han, Kaetlyn Jackson, Lauren Maestas, Teresa Moody, Genevieve Pang, Breann Ross, Eric L. Rulison, Jean I. Tsao Lyme disease is common in the northeastern United States, but rare in the southeast, even though the tick vector is found in both regions. Infection prevalence of Lyme spirochetes in host-seeking ticks, an important component to the risk of Lyme disease, is also high in the northeast and northern midwest, but declines sharply in the south. As ticks must acquire Lyme spirochetes from infected vertebrate hosts, the role of wildlife species composition on Lyme disease risk has been a topic of lively academic discussion. We compared...

In Reply We thank Fallon et al for their interest in our nationwide population-based matched cohort study on the risk of psychiatric disorders, psychiatric hospital contacts, and receipt of psychiatric medication among Danish patients with Lyme neuroborreliosis. We agree with Fallon et al that our study is limited by the fact that the indication for prescription of psychiatric medicine could not be analyzed. We also agree that part of the increased redemption of psychiatric medication might be driven by pain management. However, owing to the observational nature of our study, any theory regarding the cause of the increased redemption remains speculative. Nonetheless, it is reassuring that the increased redemption of psychiatric medicine is temporary and that the level subsides to baseline ...

Widely employed diagnostic antibody serology for Lyme disease, known as standard two-tier testing (STTT), exhibits insufficient sensitivity in early Lyme disease, yielding many thousands of false-negative test results each year. Given this problem, we applied serum antibody repertoire analysis (SERA), or next-generation sequencing (NGS)-based serology, to discover IgG and IgM antibody epitope motifs capable of detecting Lyme disease-specific antibodies with high sensitivity and specificity. Iterative motif discovery and bioinformatic analysis of epitope repertoires from subjects with Lyme disease (n = 264) and controls (n = 391) yielded a set of 28 epitope motifs representing 20 distinct IgG antibody epitopes and a set of 38 epitope motifs representing 21 distinct IgM epitopes, which perfo...

ConclusionNo significant differences in systemic immune responses represented by selected cytokines or chemokines in serum samples of patients with EM infected withB. afzelii suggest that systemic mediators are not pivotal in the pathogenesis of dissemination of early infection in the form of MEM or LB ‐associated symptoms. Localized immune responses in the skin or other pathogenetic mechanisms may be more important in this regard. (Source: Immunity, Inflammation and Disease)

Authors: Kuhn HW, Aranjuez GF, Jewett MW Abstract Borrelia burgdorferi is the causative agent of Lyme disease, the leading tick-borne illness in the United States. However, due to, in part, to the significant number of proteins of unknown function encoded across the complex fragmented genome, the molecular mechanisms of B. burgdorferi infection remain largely undefined. Previous work identified the virulence determinant gene, bbk13, which is critical for B. burgdorferi's ability to establish a productive disseminated infection. BBK13 is an immunogenic, non-surface exposed protein of unknown function predicted to harbor an N-terminal transmembrane domain and annotated as a member of the SIMPL domain protein superfamily (PF04402). In eukaryotes, SIMPL domain proteins have been show...

Wednesday 23 December 2020
Authors: Coburn J, Garcia B, Hu LT, Jewett MW, Kraiczy P, Norris SJ, Skare J Abstract Lyme disease Borrelia are obligately parasitic, tick- transmitted, invasive, persistent bacterial pathogens that cause disease in humans and non-reservoir vertebrates primarily through the induction of inflammation. During transmission from the infected tick, the bacteria undergo significant changes in gene expression, resulting in adaptation to the mammalian environment. The organisms multiply and spread locally and induce inflammatory responses that, in humans, result in clinical signs and symptoms. Borrelia virulence involves a multiplicity of mechanisms for dissemination and colonization of multiple tissues and evasion of host immune responses. Most of the tissue damage, which is seen in non-r...

Syphilis is a global, re-emerging sexually transmitted infection and congenital syphilis remains a major cause of adverse pregnancy outcomes due to bacterial infection in developing nations with a high rate of fetus loss. The molecular mechanisms involved in pathogenesis of the causative agent, Treponema pallidum subsp. pallidum remain poorly understood due to the difficulties of working with this pathogen, including the inability to grow it in pure culture. To reduce the spread of syphilis, we must first increase our knowledge of the virulence factors of T. pallidum and their contribution to syphilis manifestations. Tp0954 was predicted to be a surface lipoprotein of T. pallidum. Therefore, we experimentally demonstrated that Tp0954 is indeed a surface protein and further investigated its...

Lyme disease is a tick-borne infection caused by the bacteria Borrelia burgdorferi. Current diagnosis of early Lyme disease relies heavily on clinical criteria, including the presence of an erythema migrans rash. The sensitivity of current gold-standard diagnostic tests relies upon antibody formation, which is typically delayed and thus of limited utility in early infection. We conducted a study of blood and skin biopsy specimens from 57 patients with a clinical diagnosis of erythema migrans. Samples collected at the time of diagnosis were analyzed using an ultrasensitive, PCR-based assay employing an isothermal amplification step and multiple primers. In 75.4% of patients, we directly detected one or more B. burgdorferi genotypes in the skin. Two-tier testing showed that 20 (46.5%) of tho...

Authors: Schwartz I, Margos G, Casjens SR, Qiu WG, Eggers CH Abstract All members of the Borrelia genus that have been examined harbour a linear chromosome that is about 900 kbp in length, as well as a plethora of both linear and circular plasmids in the 5-220 kbp size range. Genome sequences for 27 Lyme disease Borrelia isolates have been determined since the elucidation of the B. burgdorferi B31 genome sequence in 1997. The chromosomes, which carry the vast majority of the housekeeping genes, appear to be very constant in gene content and organization across all Lyme disease Borrelia species. The content of the plasmids, which carry most of the genes that encode the differentially expressed surface proteins that interact with the spirochete's arthropod and vertebrate hosts, is mu...

Authors: Radolf- JD, Strle K, Lemieux JE, Strle F Abstract Lyme disease (Lyme borreliosis) is a tick-borne, zoonosis of adults and children caused by genospecies of the Borrelia burgdorferi sensu lato complex. The ailment, widespread throughout the Northern Hemisphere, continues to increase globally due to multiple environmental factors, coupled with increased incursion of humans into habitats that harbor the spirochete. B. burgdorferi sensu lato is transmitted by ticks from the Ixodes ricinus complex. In North America, B. burgdorferi causes nearly all infections; in Europe, B. afzelii and B. garinii are most associated with human disease.

Authors: Samuels DS, Lybecker MC, Yang XF, Ouyang Z, Bourret TJ, Boyle WK, Stevenson B, Drecktrah D, Caimano MJ Abstract Borrelia (Borreliella) burgdorferi, along with closely related species, is the etiologic agent of Lyme disease. The spirochete subsists in an enzootic cycle that encompasses acquisition from a vertebrate host to a tick vector and transmission from a tick vector to a vertebrate host. To adapt to its environment and persist in each phase of its enzootic cycle, B. burgdorferi wields three systems to regulate the expression of genes: the RpoN-RpoS alternative sigma (σ) factor cascade, the Hk1/Rrp1 two-component system and its product c-di-GMP, and the stringent response mediated by RelBbu and DksA. These regulatory systems respond to enzootic phase-specific signals ...

Authors: Telford SR, Goethert HK Abstract With one exception (epidemic relapsing fever), borreliae are obligately maintained in nature by ticks. Although some Borrelia spp. may be vertically transmitted to subsequent generations of ticks, most require amplification by a vertebrate host because inheritance is not stable. Enzootic cycles of borreliae have been found globally; those receiving the most attention from researchers are those whose vectors have some degree of anthropophily and, thus, cause zoonoses such as Lyme disease or relapsing fever. To some extent, our views on the synecology of the borreliae has been dominated by an applied focus, viz., analyses that seek to understand the elements of human risk for borreliosis. But, the elements of borrelial perpetuation do not nec...

Authors: Pal U, Kitsou C, Drecktrah D, Yaş ÖB, Fikrig E Abstract Borrelia burgdorferi sensu lato causes Lyme borreliosis in a variety of animals and humans. These atypical bacterial pathogens are maintained in a complex enzootic life cycle that primarily involves a vertebrate host and Ixodes spp. ticks. In the Northeastern United States, I. scapularis is the main vector, while wild rodents serve as the mammalian reservoir host. As B. burgdorferi is transmitted only by I. scapularis and closely related ticks, the spirochete-tick interactions are thought to be highly specific. Various borrelial and arthropod proteins that directly or indirectly contribute to the natural cycle of B. burgdorferi infection have been identified. Discrete molecular interactions between spirochetes and t...

Authors: O'Bier NS, Hatke AL, Camire AC, Marconi RT Abstract Lyme disease (LD) is an emerging zoonotic infection that is increasing in incidence in North America, Europe, and Asia. With the development of safe and efficacious vaccines, LD can potentially be prevented. Vaccination offers a cost-effective and safe approach for decreasing the risk of infection. While LD vaccines have been widely used in veterinary medicine, they are not available as a preventive tool for humans. Central to the development of effective vaccines is an understanding of the enzootic cycle of LD, differential gene expression of Borrelia burgdorferi in response to environmental variables, and the genetic and antigenic diversity of the unique bacteria that cause this debilitating disease.

During the natural enzootic life cycle of Borrelia burgdorferi (also known as Borreliella burgdorferi), the bacteria must sense conditions within the vertebrate and arthropod and appropriately regulate expression of genes necessary to persist within these distinct environments. bb0345 of B. burgdorferi encodes a hypothetical protein of unknown function that is predicted to contain an N-terminal helix-turn-helix (HTH) domain. Because HTH domains can mediate protein-DNA interactions, we hypothesized that BB0345 might represent a previously unidentified borrelial transcriptional regulator with the ability to regulate events critical for the B. burgdorferi enzootic cycle. To study the role of BB0345 within mammals, we generated a bb0345 mutant and assessed its virulence potential in immunocomp...

Borrelia burgdorferi causes Lyme disease, the most common tick-transmitted illness in North America. When Ixodes scapularis feed on an infected vertebrate host, spirochetes enter the tick gut along with the bloodmeal and colonize the vector. Here, we show that a secreted tick protein, I. scapularis protein disulfide isomerase A3 (IsPDIA3), enhances B. burgdorferi colonization of the tick gut. I. scapularis ticks in which ispdiA3 has been knocked down using RNA interference have decreased spirochete colonization of the tick gut after engorging on B. burgdorferi-infected mice. Moreover, administration of IsPDIA3 antiserum to B. burgdorferi-infected mice reduced the ability of spirochetes to colonize the tick when feeding on these animals. We show that IsPDIA3 modulates inflammatory responses...

Authors: Bernard Q, Hu LT Abstract Borrelia burgdorferi, the causative agent of Lyme disease, is transmitted by the bite of an infected tick. Once inoculated into the host dermis, it disseminates to various organs including distant skin sites, the heart, the joint and the nervous system. Most humans will develop an early skin manifestation called erythema migrans at the tick bite site. This can be followed by symptoms such as carditis, neuritis, meningitis, or arthritis if not treated. A specific mouse strain, C3H/HeN develops arthritis with B. burgdorferi infection whereas another strain, C57BL/6, develops minimal to no arthritis. Neither strain of mice show any skin signs of rash or inflammation. Factors that determine the presence of skin inflammation and the joint arthritis sus...

Authors: Goethert HK, Mather TN, Buchthal J, Telford SR Abstract Deer tick transmitted Borrelia burgdorferi sensu stricto (Lyme disease) and Babesia microti (babesiosis) increasingly burden public health across eastern North America. The white-footed mouse is considered to be the primary host for subadult deer ticks and the most important reservoir host for these and other disease agents. Local transmission is thought to be modulated by less reservoir competent hosts such as deer diverting ticks from feeding on mice. We measured the proportion of mouse fed or deer fed host-seeking nymphs from 4 sites during 2 transmission seasons by bloodmeal remnant analysis using a new retrotransposon-based qPCR assay. We then determined the host that was associated with the infection status of t...

Pediatric bilateral facial nerve paralysis (FNP) is a rare condition, representing less than 2% of all cases of FNP. The differential diagnosis of FNP is extensive (ranging from infectious, traumatic, neurologic, to idiopathic) and often can present as a diagnostic challenge. In contrast to unilateral presentation, bilateral FNP presents as a manifestation of serious systemic conditions, including meningitis (infectious and neoplastic), brain stem encephalitis, Guillain-Barre syndrome, sarcoidosis, Lyme disease, human immunodeficiency virus infection, leukemia, and vasculitis. In the evaluation of a child who presents with bilateral FNP, history plays the utmost role in the diagnosis. A history of rash consistent with erythema chronicum migrans, recent tick exposure, or travel to a Lyme di...

Vector-borne illnesses comprise a significant portion of human maladies, representing 17% of global infections. Transmission of vector-borne pathogens to mammals primarily occurs by hematophagous arthropods. It is speculated that blood may provide a unique environment that aids in the replication and pathogenesis of these microbes. Lipids and their derivatives are one component enriched in blood and are essential for microbial survival. For instance, the malarial parasitePlasmodium falciparum and the Lyme disease spirocheteBorrelia burgdorferi, among others, have been shown to scavenge and manipulate host lipids for structural support, metabolism, replication, immune evasion, and disease severity. In thisReview, we will explore the importance of lipid hijacking for the growth and persisten...

Authors: Tufts DM, Goodman LB, Benedict MC, Davis AD, VanAcker MC, Diuk-Wasser M Abstract Haemaphysalis longicornis, the Asian longhorned tick, is an invasive ixodid tick that has rapidly spread across the northeastern and southeastern regions of the United States since first reported in 2017. The emergence of H. longicornis presents a potential threat for livestock, wildlife, and human health as the host associations and vector potential of this invasive pest in the United States are poorly understood. Previous field data from the United States has shown that H. longicornis was not associated with natural populations of small mammals or birds, but they show a preference for medium sized mammals in laboratory experiments. Therefore, medium and large sized mammals were sampled on St...

DiscussionMusculoskeletal problems are common problems in pediatric practice with up to 15% of acute care visits being for this problem. Joint pain is a common concern for families but the differential diagnosis is extensive and needs thoughtful consideration. History is a key to discerning the potential diagnosis but also in guiding the physical examination and laboratory examination. Family history especially for systemic diseases should be considered. On physical examination all joints should be examined include sacroiliac and temporomandibular joints. Is this arthritis or arthralgia? Distinction between inflammatory and non-inflammatory joints is important. Joints with inflammation are painful or stiff after rest and improve with activity. Joints without inflammation are better afte...

In conclusion, based on these findings, combining untreated and on-treatment groups of patients with erythema migrans for research study analyses may have limitations and, depending on the study objectives, might not be preferred. Additional studies are warranted to better understand the day-to-day impact of antibiotic treatment on the presence, type, and severity of symptoms in patients with early Lyme disease.

The symptoms of Lyme disease are caused by inflammation induced by species of the Borrelia burgdorferi sensu lato complex. The various presentations of Lyme disease in the population suggest that differences exist in the intensity and regulation of the host response to the spirochete. Previous work has described correlations between the presence of regulatory T cells and recovery from Lyme arthritis. However, the effects of Foxp3-expressing CD4+ T cells existing prior to, and during, B. burgdorferi infection have not been well characterized. Here, we used C57BL/6 "depletion of regulatory T cell" mice to assess the effects these cells have on the arthritis-resistant phenotype characteristic of this mouse strain. We showed that depletion of regulatory T cells prior to infection with B. burgd...

A few years ago, Jaime Seltzer was helping coordinate research projects, grant applications and funding for a Stanford research group studying a condition called myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS). Up to 2.5 million Americans, including Seltzer, have ME/CFS, and yet it felt like almost no one paid attention to her group’s research. “What is it going to take for researchers to take ME seriously?” she and her colleagues often wondered aloud. The morbid answer, they hypothesized, was a pandemic. Since ME/CFS often follows viral infections, they feared it would take something as destructive as mass illness for the larger scientific community to take notice. Unfortunately, this year they were proven right. As the COVID-19 pandemic presses on, doctors ...

In this study, we modelled the spatial distribution of I. ricinus and associated Chlamydiales over Switzerland from 2009 to 2019. We used a total of 2293 ticks and 186 Chlamydiales occurrences provided by a Swiss Army field campaign, a collaborative smartphone application and a prospective campaign. For each tick location, we retrieved from Swiss federal datasets the environmental factors reflecting the topography, climate and land cover. We then used the Maxent modelling technique to estimate the suitability for I. ricinus and to subsequently build the nested niche of Chlamydiales bacteria. Results indicate that I. ricinus high habitat suitability is determined by higher temperature and vegetation index (NDVI) values, lower temperature during driest months and a higher percentage of artif...

This study examined the seroprevalence of B. burgdorferi s.l. in Jordan and potential demographic and zoonotic risk factors for seropositivity. Serum samples of 824 apparently healthy participants from 11 governorates in Jordan were tested for B. burgdorferi s.l. using Enzygnost Lyme link VlsE/IgG enzyme-linked immunosorbent assay. A validated questionnaire was used to collect demographic and animal exposure data. Univariate and multivariate logistic regression were used to identify factors associated with seropositivity. The results showed that 11.7 % (95 % CI, 9.3-14.0 %) of the participants were seropositive for B. burgdorferi s.l.. There was a bimodal age distribution of seroprevalence with higher seroprevalence among individuals <20 and>60 years old. After controlling for govern...

Authors: O'Keeffe KR, Oppler ZJ, Brisson D Abstract The bacterial genus, Borrelia, is comprised of vector-borne spirochete species that infect and are transmitted from multiple host species. Some Borrelia species cause highly-prevalent diseases in humans and domestic animals. Evolutionary, ecological, and molecular research on many Borrelia species have resulted in tremendous progress toward understanding the biology and natural history of these species. Yet, many outstanding questions, such as how Borrelia populations will be impacted by climate and land-use change, will require an interdisciplinary approach. The evolutionary ecology research framework incorporates theory and data from evolutionary, ecological, and molecular studies while overcoming common assumptions within each ...

Borreliosis (Lyme disease) is a spirochetal disease caused by the species complex ofBorrelia burgdorferi transmitted byIxodes spp. ticks. Recorded to be the most common tick ‐borne disease in the world, the last two decades have seen an increase in disease incidence and distribution, exceeding 360 000 cases in Europe alone. If untreated, infection may cause skin symptoms, arthritis, and neurological or cardiac complications. Borrelia spirochetes have developed strate gies to evade the mammalian host immune system. These include the complement system, which is an important first‐line defense mechanism against invading microbes. To evade the complement, spirochetes bind soluble complement regulators factor H (FH), factor H‐like protein, and C4bp to their outer surfaces.B. burgdorf...

AbstractBorreliosis (Lyme disease) is a spirochetal disease caused by the species complex ofBorrelia burgdorferi transmitted byIxodes spp. ticks. Recorded to be the most common tick ‐borne disease in the world, the last two decades have seen an increase in disease incidence and distribution, exceeding 360 000 cases in Europe alone. If untreated, infection may cause skin symptoms, arthritis, neurological or cardiac complications. Borrelia spirochetes have developed strategies to evade the mammalian host immune system. These include the complement system, which is an important first‐line defence mechanism against invading microbes. To evade the complement, spirochetes bind soluble complement regulators FH, FHL‐1 and C4bp to their outer surfaces.B. burgdorferi spirochetes can inhibit th...

In this study, we took advantage of the recently compiled spatial dataset of distribution and diversity of ticks in China, analyzed the environmental determinants of ten frequently reported tick species and mapped the spatial distribution of these species over the country using the MaxEnt model. We found that presence of urban fabric, cropland, and forest in a place are key determents of tick occurrence, suggesting ticks were likely inhabited close to where people live. Besides, precipitation in the driest month was found to have a relatively high contribution in mapping tick distribution. The model projected that theses ticks could be widely distributed in the Northwest, Central North, Northeast, and South China. Our results added new evidence on the potential distribution of a variety of...

(NEW YORK) — WNBA MVP Elena Delle Donne was shocked and hurt when her request to be medically excused for the season was denied by an independent medical panel. Having battled Lyme disease for more than a decade and now taking 64 pills a day, she thought she was definitely going to be considered high-risk to get severe illness if she contracted the coronavirus. The panel of independent doctors the league and union agreed upon to make that decision thought otherwise, ruling Monday that she was not “high risk, and should be permitted to play in the bubble.” The disease is not included on the Centers for Disease Control and Prevention’s list of underlying conditions that could put someone at an increased risk for severe illness from COVID-19.

We report the results of gene expression profiling via RNA-sequencing of primary human choroid plexus epithelial cells in vitro that were infected with Borrelia burgdorferi, the causative agent of Lyme disease. Epithelial cells were cultured with B. burgdorferi for 48 hours prior to RNA isolation. Following high-throughput sequencing via Illumina HiSeq 4000, a total of 258 differentially expressed genes were identified. Subsequent data analysis indicates an inflammatory and immune response generated by the epithelial cells following infection, marked by chemotactic cytokines and interferon stimulated genes. Several genes associated with tight and adherens junctions were found to be downregulated. These data represent the first study to investigate the impact of B. burgdorferi on choroid pl...

AbstractModified two-tier testing (MTTT) for Lyme borreliosis (i.e. confirmation with an EIA instead of an immunoblot) has been shown to have improved sensitivity compared with standard two-tier testing (STTT) in samples from American patients, without losing specificity. The current study assesses the sensitivity and specificity of various algorithms of MTTT in European patients with erythema migrans (EM) as a model disease for early Lyme borreliosis, and in appropriate controls. Four different immunoassays were used in the first tier, followed by either an immunoblot or the C6-EIA, or were used as standalone single-tier test. These tests were performed on consecutively collected sera of 228 Dutch patients with physician-diagnosed EM in the setting of general practice, 231 controls from...

Pathogen specific antibody responses need to be tightly regulated to generate protective but limit self-reactive immune responses. While loss of humoral tolerance has been associated with microbial infections, the pathways involved in balancing protective versus autoreactive antibody responses in humans are incompletely understood. Studies in classical mouse model systems have provided evidence that balancing of immune responses through inhibitory receptors is an important quality control checkpoint. Genetic differences between inbred mouse models and the outbred human population and allelic receptor variants not present in mice, however, argue for caution when directly translating these findings to the human system. By studyingBorrelia burgdorferi infection in humanized mice reconstituted...

Compared to the standard two-tiered testing (STTT) algorithm for Lyme disease serology using an enzyme immunoassay (EIA) followed by Western blotting, data from the United States suggest that a modified two-tiered testing (MTTT) algorithm employing two EIAs has improved sensitivity to detect early localized Borrelia burgdorferi infections without compromising specificity. From 2011 to 2014, in the Canadian province of Nova Scotia, where Lyme disease is hyperendemic, sera submitted for Lyme disease testing were subjected to a whole-cell EIA, followed by C6 EIA and subsequently IgM and/or IgG immunoblots on sera with EIA-positive or equivocal results. Here, we evaluate the effectiveness of the MTTT algorithm compared to the STTT approach in a Nova Scotian population. Retrospective chart revi...

Authors: Rochlin I, Toledo A Abstract Ticks are the most important vectors of human pathogens, leading to increased public health burdens worldwide. Tick-borne pathogens include viruses (e.g. tick-borne encephalitis and Powassan); bacteria, such as the causative agents of Lyme disease, spotted fever rickettsiosis and human anaplasmosis; and malaria-like protozoan parasites causing babesiosis. Tick-borne diseases are emerging due to the geographical expansion of their tick vectors, especially in the northern hemisphere. Two examples of this phenomenon are Ixodes scapularis and Amblyomma americanum, which have expanded their ranges in the USA in recent decades and are responsible for the continuous emergence of Lyme disease and human ehrlichiosis, respectively. This phenomenon is als...

Mitochondria, chloroplasts and several species of bacteria have outer membrane proteins (OMPs) that perform many essential biological functions. The β -barrel assembly machinery (BAM) complex is one of the OMPs of Borrelia burgdorferi, the pathogenic spirochete that causes Lyme disease, and its BamA component (BbBamA) includes a C-terminal β -barrel domain and five N-terminal periplasmic polypeptide-transport-associated (POTRA) domains, which together perform a central transport function. In the current work, the production, crystallization and X-ray analysis of the three N-terminal POTRA domains of BbBamA (BbBamA-POTRA P1 – P3; residues 30 – 273) were carried out. The crystals of BbBamA-POTRA P1 – P3 belonged to space group P21, with unit-cell parameters a = 45.353, b = 111.538, c...

The laboratory diagnosis of Lyme disease relies upon serologic testing. A standard or modified two-tiered testing algorithm is used to enhance the accuracy of antibody detection. However, this approach suffers from a lack of sensitivity in early Lyme disease.

Lyme disease (LD) is an increasing public health problem. Current laboratory testing is insensitive in early infection, the stage at which appropriate treatment is most effective in preventing disease sequelae. The Lyme Disease Biobank (LDB) collects samples from individuals with symptoms consistent with early LD presenting with or without erythema migrans (EM) or an annular, expanding skin lesion and uninfected individuals from areas of endemicity. Samples were collected from 550 participants (298 cases and 252 controls) according to institutional review board-approved protocols and shipped to a centralized biorepository. Testing was performed to confirm the presence of tick-borne pathogens by real-time PCR, and a subset of samples was tested for Borrelia burgdorferi by culture. Serology ...

Borrelia burgdorferi encodes a functional homolog of canonical Lon protease termed Lon-2. In addition, B. burgdorferi encodes a second Lon homolog called Lon-1. Recent studies suggest that Lon-1 may function differently from the prototypical Lon protease. However, the function of Lon-1 in B. burgdorferi biology remains virtually unknown. Particularly, the contribution of Lon-1 to B. burgdorferi fitness and infection remains hitherto unexplored. Herein, we show that Lon-1 plays a critical role for the infection of B. burgdorferi in a mammalian host. We found that lon-1 was highly expressed during animal infection, implying an important function of this protein in bacterial infection. We further generated a lon-1 deletion mutant and an isogenic complemented strain. Relative to that of the wi...

Spirochetes of the genus Borrelia are divided into relapsing fever borreliae and Lyme disease borreliae. Immunoserological assays have been poorly developed for relapsing fever borreliae, where direct detection methods are more adapted to the pathophysiology of these infections presenting with massive bacteraemia. However, emergence of the novel agent of relapsing fever B. miyamotoi has renewed interest in serology in this context. In Lyme disease, because direct detection methods show low sensitivity, serology plays a central role in the diagnostic strategy. This diagnostic strategy is based on a two-tier methodology involving a first test (ELISA) with high sensitivity and acceptable specificity and a second, more specific test (western blot) for diagnostic confirmation. The most frequent...

Authors: Melenotte C, Mezouar S, Mège JL, Gorvel JP, Kroemer G, Raoult D Abstract One quarter of all cancers are linked to infectious diseases. The link between viral infection and cancer has been widely studied, but few reports have focused on the carcinogenic role of bacterial infection. Nonetheless, Helicobacter pylori, Chlamydia psittaci, Coxiella burnetii, Borrelia burgdorferi and Campylobacter jejuni are bacteria that can be associated with non-Hodgkin's lymphoma (NHL), the most common haematologic malignancy. Here, we review the evidence in favour of a link between these bacterial infections and NHL. Sero-epidemiological observation makes it possible to identify a link between H. pylori, C. burnetii, B. burgdorferi infection and NHL. Helicobacter pylori, Chlamydia psittaci,...

Conclusion: Diagnostic improvements in sensitivity of LD testing without significant loss of specificity have been consistently reported when MTTT is compared with STTT in studies conducted in highly LD endemic regions. Our working group agrees with the recommendation by the United States Centers for Disease Control that serological testing for LD using MTTT is an acceptable alternative to STTT. This recommendation is contingent on development and implementation of comprehensive validation studies on the performance of MTTT vs STTT within the Canadian context, including evaluation of the test performance in areas of low endemicity for LD.

Authors: Pace EJ, O'Reilly M Abstract Tickborne diseases that affect patients in the United States include Lyme disease, Rocky Mountain spotted fever (RMSF), ehrlichiosis, anaplasmosis, babesiosis, tularemia, Colorado tick fever, and tickborne relapsing fever. Tickborne diseases are increasing in incidence and should be suspected in patients presenting with flulike symptoms during the spring and summer months. Prompt diagnosis and treatment can prevent complications and death. Location of exposure, identification of the specific tick vector, and evaluation of rash, if present, help identify the specific disease. Lyme disease presents with an erythema migrans rash in 70% to 80% of patients, and treatment may be initiated based on this finding alone. RMSF presents with a macular rash...

Lyme borreliosis is a tick-borne disease caused by the Borrelia burgdorferi sensu lato complex. Bio-Rad Laboratories has developed a fully automated multiplex bead-based assay for the detection of IgM and IgG antibodies to B. burgdorferi. The BioPlex 2200 Lyme Total assay exhibits an improved rate of seropositivity in patients with early Lyme infection. Asymptomatic subjects from endemic and nonendemic origins demonstrated a seroreactivity rate of approximately 4% that was similar to other commercial assays evaluated in this study. Coupled to this result was the observation that the Lyme Total assay retained a high first-tier specificity of 96% while demonstrating a relatively high sensitivity of 91% among a well-characterized CDC Premarketing Lyme serum panel. The Lyme Total assay also pe...

In this study, we developed a new filter-based chemical extraction technique that allows measurement of high quality Borrelia spp. spectra from less than 100,000 bacteria per spot in MALDI-TOF MS. We used 49 isolates of 13 different species to produce the largest mass-library for Borrelia spp. so far and to validate the protocol. The library was successfully established and identifies >96% of used isolates correctly to species level. Cluster analysis on the sum spectra was applied to all the different isolates, which resulted in tight cluster generation for most species. Comparative analysis of the generated cluster to a phylogeny based on concatenated multi-locus sequence typing genes provided a surprising homology. Our data demonstrate that the technique described here can be used for...

In this study, we demonstrated that immunization with CspZ-YA, a CspZ mutant protein with no FH-binding activity, protected mice from infection by several spirochete genotypes introduced via tick feeding. We found that the sera from CspZ-YA-vaccinated mice more efficiently eliminated spirochetes and blocked CspZ FH-binding activity than sera from CspZ-immunized mice. We also found that vaccination with CspZ, but not CspZ-YA, triggered the production of anti-FH antibodies, justifying CspZ-YA as an LD vaccine candidate. The mechanistic and efficacy information derived from this study provides insights into the development of a CspZ-based LD vaccine. (Source: Infection and Immunity)

ConclusionsBorrelial lymphocytoma is a rare manifestation of Lyme disease in North America, although not uncommon in Europe. Diagnosis is made by the presence of a painless erythematous swelling typically found on the ear lobe, nipples, or testes. Laboratory tests are available but with low sensitivity, therefore, a high index of suspicion is necessary for a clinical diagnosis to be made. Treatment for isolated borrelial lymphocytoma is doxycycline 4 mg/kg up to 100 mg twice daily, whereas for children less than 8 years of age amoxicillin 50 mg/kg divided three times daily, for 3–4 weeks, is preferred.

WASHINGTON — Blood tests for the coronavirus could play a key role in deciding whether millions of Americans can safely return to work and school. But public health officials warn that the current “Wild West” of unregulated tests is creating confusion that could ultimately slow the path to recovery. More than 70 companies have signed up to sell so-called antibody tests in recent weeks, according to U.S. regulators. Governments around the world hope that the rapid tests, which typically use a finger-prick of blood on a test strip, could soon ease public restrictions by identifying people who have previously had the virus and have developed some immunity to it. But key questions remain: How accurate are the tests, how much protection is needed and how long will that protec...

(Bloomberg) — There are four critical facets of pandemic prevention, according to Lee Hannah, senior scientist at Conservation International. Three of them make immediate sense against the backdrop of our current emergency: stockpile masks and respirators; have testing infrastructure ready; and ban the global wildlife trade, including the open animal markets where COVID-19 may have first infected people. His fourth recommendation is more grandiose: “Take care of nature.” The assault on ecosystems that allowed COVID-19 to jump from animals to humans went far beyond merchants hunting and selling rare wildlife. Biodiversity—that is, the health of the entire ecosystem—can restrain pathogens before they ever leave the wild. “We need to tell people right now t...

The deer tick Ixodes scapularis transmits a variety of disease agents in the United States, spreading the bacteria that causes Lyme borreliosis, the protozoan agent of babesiosis, and viruses such as Powassan. However, a variety of other organisms have also evolved symbiotic relationships with this tick species, and it seems likely that some of these microbes have simultaneously coevolved mechanisms to impact each other and their tick host. The number of organisms identified as I. scapularis symbionts has increased seemingly exponentially with the advent of PCR and next generation sequencing technologies, but convincing arguments have proposed that some of these are of environmental origin, unadapted to surviving the physiological conditions of the tick or that they are artifacts of ultras...

I read with interest the editorial by Strom1 about functional neurologic disorders (FNDs). As a treating physician, I have struggled with the multiple diagnostic labels attached to these patients by physicians of different medical specialties during the course of their clinical disease presentation. A neurologist may assign a patient who presents with chronic fatigue the diagnostic labels of narcolepsy, idiopathic hypersomnia, or chronic Lyme disease. A rheumatologist may assign the label of collagen vascular disease, and a psychiatrist may diagnose depression. This diagnostic ambiguity is troublesome for patients and clinicians alike. I contend that even the term FND needs to be revisited. A patient should be broadly labeled as having a functional disorder and only after characterization ...

We examined gene expression patterns in the blood of individuals with early disseminated LD at the time of diagnosis (Acute LD) and also at approximately 1 month and 6 months following antibiotic treatment. A distinct acute LD profile was observed that was sustained during early convalescence (1 month) but returned to control levels six months after treatment. Using a computer learning algorithm, we identified sets of 20 classifier genes that discriminate LD from other bacterial and viral infections. In addition, these novel LD biomarkers are highly acurate in distinvuishing patients with acute LD from healthy subjects and in discriminating between individuals with active and resolved infecitons. This computational approach offers the potential for more accurate diagnosis of early dissmina...

Credit: United Nations By Thalif DeenUNITED NATIONS, Mar 24 2020 (IPS) When US President Donald Trump repeatedly characterized the fast-spreading COVID-19 as a “Chinese virus” last week, it prompted some white supremacists to resurrect an age old ethnic slur against Chinese and East Asians: the “Yellow Peril” which, in a bygone era, was touted as a xenophobic threat to the Western world. But Tendayi Achiume, UN Special Rapporteur on Contemporary Forms of Racism, Racial Discrimination and Xenophobia, is highly critical of the racist interpretation to a disease which has claimed over 16,500 deaths worldwide and accounted for more than 378,000 infections, with the epicenter shifting from China to Europe.

Borrelia burgdorferi sensu lato, the causative agent of tick-borne Lyme borreliosis (LB), has a limited metabolic capacity and needs to acquire nutrients, such as amino acids, fatty acids, and nucleic acids, from the host environment. Using X-ray crystallography, liquid chromatography-mass spectrometry, microscale thermophoresis, and cellular localization studies, we show that basic membrane protein D (BmpD) is a periplasmic substrate-binding protein of an ABC transporter system binding to purine nucleosides. Nucleosides are essential for bacterial survival in the host organism, and these studies suggest a key role for BmpD in the purine salvage pathway of B. burgdorferi sensu lato. Because B. burgdorferi sensu lato lacks the enzymes required for de novo purine synthesis, BmpD may play a v...

Authors: Yeung C, Al-Turki M, Baranchuk A Abstract Lyme carditis (LC) is an early-disseminated manifestation of Lyme disease, most commonly presenting as high-degree atrioventricular block (AVB). The degree of AVB can fluctuate rapidly within minutes, and progression to third-degree AVB is potentially fatal if not recognized and managed promptly. However, the AVB in LC is often transient, and usually resolves with appropriate antibiotic therapy. LC should be on the differential diagnosis in young patients presenting with new high-degree AVB and factors that increase the index of suspicion for Lyme disease. The Suspicious Index in Lyme Carditis (SILC) score helps clinicians risk stratify for LC. A systematic approach to the diagnosis and treatment of LC minimizes the unnecessary imp...

Authors: Strnad M, Rego ROM Abstract Lyme borreliosis is a vector-borne infection caused by bacteria under the Borrelia burgdorferi sensu lato complex, both in Europe and North America. Differential gene expression at different times throughout its infectious cycle allows the spirochete to survive very diverse environments within different mammalian hosts as well as the tick vector. To date, the vast majority of data about spirochetal proteins and their functions are from genetic studies carried out on North American strains of a single species, i.e. B. burgdorferi sensu stricto. The whole-genome sequences recently obtained for several European species/strains make it feasible to adapt and use genetic techniques to study inherent differences between them.

In this study, we explored and compared the climatic and landscape factors that shape the spatial patterns of human Lyme cases in these two regions, using the generalized linear mixed models. Our results showed that climatic variables generally had opposite correlations with Lyme disease risk, while landscape factors usually had similar effects in these two regions.

Lyme endocarditis is extremely rare manifestation of Lyme disease. The clinical manifestations of Lyme endocarditis are non-specific and can be very challenging diagnosis to make when it is the only manifestation of the disease. Until now, only a few cases where reported. Physicians should keep in mind the possibility of borrelial etiology of endocarditis in endemic areas. Appropriate valve tissue sample should be sent for histopathology, culture, and PCR especially in case of endocarditis of unknown origin PCR on heart valve samples is recommended. With more frequent PCR, Borrelia spp. may be increasingly found as a cause of infective endocarditis. Prompt diagnosis and treatment of Lyme carditis may prevent surgical treatment and pacemaker implantations. Due to climate change and global w...

The incidence of tick-borne infections in the United States has risen significantly in the past decade. Ticks can transmit a variety of pathogens, including bacteria, protozoa, and viruses, that can cause serious illnesses. Therefore, the use of rapid, sensitive, and specific multiplex tests is important to identify the pathogen(s) in the acute phase and determine appropriate treatment to minimize the severity of the disease. The purpose of this study was to evaluate ChromaCode’s research use only (RUO) nine-target high-definition PCR (HDPCR) tick-borne pathogen (TBP) panel using 379 retrospective, remnant whole-blood and synovial fluid specimens previously submitted to Associated Regional and University Pathologists (ARUP) Laboratories and tested by clinically validated real-time PC...

ORONO, Maine (AP) — More than a third of the deer ticks submitted to a Maine lab last year tested positive for Lyme disease, a surveillance report from the lab said. The report is from the University of Maine Tick Lab. The lab found that a smaller percentage of ticks tested positive for anaplasmosis and babesiosis, which are other tick-borne diseases. The tick lab’s manager, Griffin Dill, said the information will help authorities learn how fast the ticks are spreading in the state. The study is the first of its kind in Maine, the Bangor Daily news reported. The report found that just shy of 39% of deer ticks tested positive for Lyme. The data also show ticks were more frequently found higher on the bodies of children than adults. Lyme disease can cause symptoms such as neck stiffn...

AbstractInterdisciplinary approaches are merited when attempting to understand the complex and idiosyncratic processes driving the spillover of pathogens from wildlife and vector species to human populations. Public health data are often available for zoonotic pathogens but can lead to erroneous conclusions if the data have been spatially or temporally aggregated. As an illustration, we use human Lyme disease incidence data as a case study to examine correlations between mammalian biodiversity, fried chicken restaurants and obesity rates on human disease incidence. We demonstrate that Lyme disease incidence is negatively correlated with mammalian biodiversity, the abundance of fried chicken restaurants and obesity rates. We argue, however, that these correlations are spurious, representing...

It has been shown that cellular metabolism of immune cells changes when exposed to or infected by several pathogens: while this is often an adaptation of the host cells to the infection, sometimes it represents a mechanism through which the pathogens evade immune activation. Borrelia burgdorferi sensu lato, the causative agent of Lyme borreliosis, is a pathogen that highly depends on the host to survive, as the bacterium lacks many central metabolic pathways to generate its own nutrients. It is therefore quite likely that the bacterium interact...

AbstractLyme disease (LD) is endemic in many regions of the Northeastern United States. Given the elusive nature of the disease, a systematic approach to identify efficient interventions would be useful for policymakers in addressing LD. We used Markov modeling to investigate the efficiency of interventions. These interventions range from awareness-based to behavioral-based strategies. Targeting animal reservoirs of LD using fungal spray or bait boxes did not prove to be an effective intervention. Results of awareness-based interventions, including distribution of signage, fliers, and presentations, implementable in different geographical scales, suggest that policymakers should focus on these interventions, as they are both cost-effective and have the highest impact on lowering LD risk.

Lyme disease (LD), which is caused by genospecies of the Borrelia burgdorferi sensu lato complex, is the most common vector-borne disease in the Northern hemisphere. Spirochetes are transmitted by Ixodes ticks and maintained in diverse vertebrate animal hosts. Following tick bite, spirochetes initially establish a localized infection in the skin. However, they may also disseminate hematogenously to several distal sites, including heart, joints, or the CNS. Because they need to survive in diverse microenvironments, from tick vector to mammalian hosts, spirochetes have developed multiple strategies to combat the numerous host defense mechanisms. One of these strategies includes the production of a number of complement-regulator acquiring surface proteins (CRASPs) which encompass CspA, CspZ, ...

ConclusionA discriminant analysis was shown to be useful to distinguish the independently most important cytokines/chemokines (CXCL1, GM-CSF, IL-7 and IL-10) in CSF, in order to discriminate LNBtot patients from Non-LNB patients. An IL-10/CXCL1 ratio was shown to have a promising diagnostic profile with a better performance than the chemokine CXCL13 in CSF. However, further evaluation is required to address future possible usefulness of these cytokines and chemokines in laboratory diagnostics in LNB, including control groups with neuro-inflammation. No significant associations were found between CSF immune mediator levels and clinical presentation or recovery in pediatric LNB patients. (Source: Ticks and Tick borne Diseases)

Authors: Song S, Wood TK Abstract Stress is ubiquitous for bacteria and can convert a subpopulation of cells into a dormant state known as persistence, in which cells are tolerant to antimicrobials. These cells revive rapidly when the stress is removed and are likely the cause of many recurring infections such as those associated with tuberculosis, cystic fibrosis, and Lyme disease. However, how persister cells are formed is not understood well. Here we propose the ppGpp ribosome dimerization persister (PRDP) model in which the alarmone guanosine pentaphosphate/tetraphosphate (henceforth ppGpp) generates persister cells directly by inactivating ribosomes via the ribosome modulation factor (RMF), the hibernation promoting factor (Hpf), and the ribosome-associated inhibitor (RaiA).

The prevalence of tickborne diseases worldwide is increasing virtually unchecked due to the lack of effective control strategies. The transmission dynamics of tickborne pathogens are influenced by the tick microbiome, tick co-infection with other pathogens, and environmental features. Understanding this complex system could lead to new strategies for pathogen control, but will require large-scale, high-resolution data. Here, we introduce Project Acari, a citizen science-based project to assay, at single-tick resolution, species, pathogen infection status, microbiome profile, and environmental conditions of tens of thousands of ticks collected from numerous sites across the United States. In the first phase of the project, we collected more than 2,400 ticks wild-caught by citizen scientists...

AUGUSTA, Maine (AP) — Maine reported a record number of Lyme disease cases last year, and the number could rise as data continues to trickle in, officials said Thursday. There were at least 2,079 cases in 2019, the Maine Center for Disease Control and Prevention reported. It’s too early to say why the numbers grew last year. But the numbers underscore the importance of taking precautions to avoid tick bites, said Dr. Nirav Shah, director of the Maine CDC. Winter is a time of low ticket activity. But ticks can be active when the temperature climbs above 40, as it did last weekend in Maine. The state also experienced increases in two other tickborne diseases, with 685 cases of anaplasmosis and 138 cases of babesiosis. Lyme disease is caused by bacteria carried by infected deer ticks....

Ixodes ticks are the main vectors for a number of zoonotic diseases, including Lyme disease. Ticks secrete saliva directly into a mammalian host while feeding on the host's blood. This action serves to modulate host immunity and coagulation, thus allowing ticks to attach and feed upon their host. One of the most extensively studied components of tick saliva is Salp15. Research has shown that this protein binds specifically to CD4 molecules on the surface of T lymphocytes, interferes with TCR-mediated signaling transduction, inhibits CD4+ T cell activation and proliferation, and impedes the secretion of interleukin 2 (IL-2). Salp15 also binds specifically to dendritic cell dendritic cell-specific intercellular adhesion molecule-3-grabbing non-integrin (DC-SIGN) to up-regulate the expression...

Lyme disease, also known as Lyme borreliosis, is the most common tick-transmitted disease in the Northern Hemisphere. The disease is caused by the bacterial spirochete Borrelia burgdorferi and other related Borrelia species. One of the many fascinating features of this unique pathogen is an elaborate system for antigenic variation, whereby the sequence of the surface-bound lipoprotein VlsE is continually modified through segmental gene conversion events. This perpetual changing of the guard allows the pathogen to remain one step ahead of the acquired immune response, enabling persistent infection. Accordingly, the vls locus is the most evolutionarily diverse genetic element in Lyme disease–causing borreliae. Small stretches of information are transferred from a series of silent cassettes...

Several well-controlled clinical trials have shown that prolonged antibiotic therapy has no benefit in relieving posttreatment Lyme disease symptoms. However, some insist that such symptoms are due to a persistent Borrelia burgdorferi infection requiring prolonged antibiotic therapy to resolve. This unproven view is bolstered by the results of in vitro experiments where small numbers of viable B. burgdorferi can be detected after treatment with antibiotics. The results described in the present work suggest that the presence of persisters can best be explained by classic biochemical kinetics and that there are alternative explanations for this phenomenon that appears to have no clinical significance.

Conclusions: A significant increase (P = .02) in Lyme arthritis cases was observed at Oishei Children's Hospital of Buffalo. Lyme arthritis may clinically present similarly to other forms of arthritis, such as oligoarticular juvenile idiopathic arthritis, so health care providers should be aware of distinguishing clinical features, which include rapid onset of swelling and patient age. Because the geographic area of endemic Lyme disease is expanding, all health care providers need to be aware of Lyme arthritis as a possible diagnosis.

Upon activation, this powerful defense mechanism can elicit inflammatory responses, lyse non-self-cells, or mark them for opsonophagocytic removal. Blood-feeding arthropods thus require the ability to block host complement activation in the bloodmeal to prevent undesired cell or tissue damage during feeding.

(CNN/CBS) — The climate crisis is making us more vulnerable to ticks in an unprecedented and growing threat to public health, according to a new report. Bacterial and protozoan tick-borne diseases doubled in the United States between 2004 and 2016, the report notes, and in 2017, more than 90% of the 60,000 vector-borne diseases in the United States were linked to these particular bloodsucking bugs. The warmer temperatures brought by the climate crisis, in addition to ecological changes and reforestation, have extended the bugs’ range into regions that had not seen certain types of ticks for many decades, if ever. And the report published in the New England Journal of Medicine Tuesday warns that we should be “bracing for the worst.” The lone star tick, a tick disting...

Strain CA690T, which was cultivated from a questing Ixodes spinipalpis nymph in the San Francisco Bay area, CA, was determined to be genetically distinct from all other described species belonging to the Borrelia burgdorferi sensu lato complex. The genome, including plasmids, was assembled using a hybrid assembly of short Illumina reads and long reads obtained via Oxford Nanopore Technology. We found that strain CA690T has a main linear chromosome c...

In this study, we determined the crystal structures of the key outer surface protein BBE31 from B. burgdorferi and its orthologous protein BSE31 (BSPA14S_RS05060 gene product) from B. spielmanii. BBE31 is known to be important for the transfer of B. burgdorferi from the gut to the hemolymph in the tick after a tick bite. While BBE31 exerts its function by interacting with the Ixodes scapularis tick gut protein TRE31, structural and mass spectrometry data revealed that BBE31 has a glutathione (GSH) covalently attached to Cys142 suggesting that the protein may have acquired some additional functions in contrast to its orthologous protein BSE31, which lacks any interactions with GSH. In the current study, in addition to analyzing the potential reasons for GSH binding, the three-dimensional st...

We report a case of suspected Lyme neuroborreliosis (LNB) where the patient's sole symptom was chronic, intermittent episodes of unilateral ear pain. This case was unusual because this patient did not show any other neurological or extraneurological symptoms of Lyme disease. LNB is a manifestation of infection by Borrelia burgdorferi spirochetes that can manifest in a number of different clinical presentations depending on the nervous system dissemination of the bacteria. Most commonly, these neurological findings present as peripheral nerve radiculopathies, but rarer involvement of the central nervous system (CNS) can occur if a patient goes untreated. Most often, CNS involvement presents as meningitis with increased lymphocytes but can, in rarer cases, involve the spinal cord ...

We present a case of a man with genital condyloma acuminatum with a positive T. pallidum IHC stain but negative T. pallidum serologies and no syphilitic symptoms. It has been shown that the T. pallidum antibody IHC can cross-react, staining other spirochetes, including Borrelia burgdorferi and the Brachyspira family of intestinal spirochetes. Because of the proximity of our patient's lesions to the anus, and the persistently negative T. pallidum serologies, we believe nontreponemal spirochetes colonized the condyloma, giving a false-positive T. pallidum IHC. This cross-reactivity is a potential diagnostic pitfall and is important for the dermatopathologist to recognize, thereby avoiding false diagnosis of syphilis.

For Borrelia burgdorferi and tick-borne encephalitis (TBE) virus, transmission of infection from one generation of ticks to another occurs when older nymphal ticks infect younger larval ticks feeding on the same host, either indirectly via systemic infection of the vertebrate host or directly when feeding in close proximity. Here, expressions for the basic reproduction number, R0, and the related tick type-reproduction number, T, are derived...

Lyme disease is caused by a tick-borne bacterium Borrelia sp. This zoonotic infection is common in the Northern Hemisphere, e.g., Europe. Clinical presentation may involve multisystem symptoms and depends on the stage of the disease. The involvement of nervous system in Lyme disease is commonly referred to as neuroborreliosis. Neuroborreliosis may involve meningitis, mononeuritis multiplex, or cranial neuritis including the inflammation of vestibulocochlear nerve. In the late or chronic stage of Lyme disease, vestibular involvement may be the sole presentation, although such cases are rare. Our study was designed to present our own case and review the available literature reporting cases of neuroborreliosis with vertigo/dizziness and severe balance instability as a main disease symptom.

Authors: Federizon J, Frye A, Huang WC, Hart TM, He X, Beltran C, Marcinkiewicz AL, Mainprize IL, Wills MKB, Lin YP, Lovell JF Abstract Outer surface protein A (OspA) is a Borrelia lipoprotein and an established Lyme disease vaccine target. Admixing non-lipidated, recombinant B. burgdorferi OspA with liposomes containing cobalt porphyrin-phospholipid (CoPoP) resulted in rapid, particulate surface display of the conformationally intact antigen. Particleization was serum-stable and led to enhanced antigen uptake in murine macrophages in vitro. Mouse immunization using CoPoP liposomes that also contained a synthetic monophosphoryl lipid A (PHAD) elicited a Th1-biased OspA antibody response with higher IgG production compared to other vaccine adjuvants.

Authors: Sabrina H, Volker F, Gerhard DG, Gerit F, Durdica M, Ethan RR, Mercy O, Andreas S, Gabriele M Abstract Borrelia turcica, a member of the reptile-associated Borrelia clade, is vectored by Hyalomma aegyptium. The only suggested reservoir hosts of B. turcica are tortoises of the genus Testudo. Borrelia turcica has been described to occur in several Southeastern European countries including Turkey, Romania, Bulgaria and Greece but so far nothing is known about the relationship of these populations and whether or how they are structured. Using multilocus sequence typing (MLST) on eight chromosomally located housekeeping loci (clpA, clpX, nifS, pepX, pyrG, recG, rplB and uvrA) we analyzed 43 B. turcica isolates from Serres, Greece (n = 15) collected in 2017 and Izmir, Turkey...

This study documents a high prevalence in ticks of Rickettsia spp. thought to be endosymbionts, a low prevalence of relapsing fever group Borrelia in ticks, and a lack of detection of Lyme disease-group Borrelia in both ticks and mammals in an east Texas forested recreation area. Additionally, we observed low questing tick density in areas with a history of controlled burns. These results expand knowledge of tick-borne disease ecology in east Texas which can aid in directing future investigative, modeling, and management efforts. (Source: Ticks and Tick borne Diseases)

Authors: Norte AC, Lopes de Carvalho I, Núncio MS, Araújo PM, Matthysen E, Albino Ramos J, Sprong H, Heylen D Abstract Wild birds are frequently exposed to the zoonotic tick-borne bacteria Borrelia burgdorferi sensu lato (s.l.), and some bird species act as reservoirs for some Borrelia genospecies. Studying the tropism of Borrelia in the host, how it is sequestered in different organs, and whether it is maintained in circulation and/or in the host's skin is important to understand pathogenicity, infectivity to vector ticks and reservoir competency.We evaluated tissue dissemination of Borrelia in blackbirds (Turdus merula) and great tits (Parus major), naturally and experimentally infected with Borrelia genospecies from enzootic foci. We collected both minimally invasive biologica...

CONCLUSION: Different specific molecules of the vector, pathogen and host result in LNB establishment. After B. burgdorferi species penetrate host skin through a tick bite, they are confronted by the immune defenses of the host. However, they are helped by specific proteins in different interactions, and the disease is established. The interactions between the vector, pathogen and host are shown in Table 1 and Figure 1. Knowledge of these molecular interactions can aid development of therapeutics against LNB and LD. Others: We systematically describe the different molecular tick-pathogen-host interactions.

Discussion Lyme disease (LD) is caused by several genospecies of Borrelia burgdorferi senu lato that are transmitted by ticks of the Ixodes ricinus complex. In the U.S. and Europe it is the most common vector-borne disease. It is named for Lyme, Connecticut in the 1970s when it was “discovered,” but there are reports of LD-type disease in Europe since 1883. There are 18 distinct genospecies with B. afzelii, B. garinii and B. burgdorferi sensu stricto being the 3 most common ones causing human infection. There are many species of Ixodes ticks but only 4 commonly bite humans. Ixodes ricinus mainly in Europe, I, persultcatus in Asia, I. scapularis in the eastern and central US, and I. pacificus in the western US and Canada. However I. pacificus is rarely infected and accounts for ...

ConclusionsAlthough peripheral facial palsy was predominantly idiopathic (75.3%) in our cohort, the disease was caused in approximately 25% of the patients by factors which require specific treatment. In the present study, CSF analysis proved to be the leading method for the diagnosis of Ramsay-Hunt-Syndrome, Lyme Neuroborreliosis, and other CNS infections. These subgroups made up approximately 15% of our cohort. To detect these subgroups reliably, routine use of CSF analysis in peripheral facial palsy may be advisable, whereas MRI proved to be useful for exclusion of otogenic and neoplastic processes with a sensitivity of 83% and 88%. We found that the use of MRI with contrast-enhancing compounds does not provide additional diagnostic information on the day of hospital admission. Hence, t...

Abstract: Borrelia burgdorferi, the causative organism of Lyme disease, has been linked to the development of scleroatrophic skin conditions including morphea, although this association remains controversial. The possibility that tick bite with or without concurrent Borrelia infection instigates that morphea development is important to recognize because this could prompt further workup for Lyme disease, or other tick-borne illness, which, when untreated, can have devastating consequences. Here, we report a case of a woman with a history of previous tick bite in the location of morphea. This prompted further workup, including serologies that were negative for borrelia. The patient declined empiric treatment with doxycycline. It is important to be aware that morphea may represent a consequ...

Conventional two-tiered testing (CTTT) for Lyme disease includes a first-tier enzyme immunoassay (EIA) followed by a supplemental immunoblot, and modified two-tiered testing (MTTT) relies on two different sequential EIAs without the inclusion of an immunoblot. MTTT has shown promising results as an alternative strategy for the diagnosis of Lyme disease in adults but has not yet been evaluated in children. We performed a cross-sectional study of children and adolescents ≤21 years of age undergoing clinical investigation for suspected Lyme disease. Serum specimens were analyzed with both a whole-cell sonicate (WCS) and a C6 EIA, with a supplemental immunoblot if either EIA was positive or equivocal. We compared CTTT (WCS EIA followed by supplemental immunoblot) to MTTT (WCS EIA followed b...

Mothers can transmit antibodies to their offspring, which can provide short-term, strain-specific protection against infection. Few experimental studies have investigated this phenomenon for multiple-strain zoonotic pathogens occurring in wildlife reservoir hosts. The tick-borne bacterium Borrelia afzelii causes Lyme disease in Europe and consists of multiple strains that cycle between the tick vector (Ixodes ricinus) and vertebrate hosts such as the bank vole (Myodes glareolus). We used a controlled experiment to show that female bank voles infected with ...

A basic feature of infection caused by Borrelia burgdorferi, the etiological agent of Lyme borreliosis, is that persistent infection is the rule in its many hosts. The ability to persist and evade host immune clearance poses a challenge to effective antimicrobial treatment. A link between therapy failure and the presence of persister cells has started to emerge. There is growing experimental evidence that viable but noncultivable spirochetes persist following treatment with several different antimicrobial agents. The current study utilized the mouse model to evaluate if persistence occurs following antimicrobial treatment in disease-susceptible (C3H/HeJ [C3H]) and disease-resistant (C57BL/6 [B6]) mouse strains infected with B. burgdorferi strains N40 and B31 and to confirm the generality o...

The periplasmic lipoprotein BB0365 of the Lyme disease agentBorrelia burgdorferi is expressed throughout mammalian infection and is essential for all phases of Lyme disease infection; its function, however, remains unknown. In the current study, our structural analysis of BB0365 revealed the same structural fold as that found in the NqrC and RnfG subunits of the NADH:quinone and ferredoxin:NAD+ sodium ‐translocating oxidoreductase complexes, which points to a potential role for BB0365 as a component of the sodium pump. Additionally, BB0365 coordinated Zn2+ by the His51, His55, His140 residues, and the Zn2+‐binding site indicates that BB0365 could act as a potential metalloenzyme; therefore, this structure narrows down the potential functions of BB0365, an essential protein forB. bur...

The spirochete Borrelia burgdorferi, the causative agent of Lyme disease, is internalized by macrophages and processed in phagolysosomes. Phagosomal compaction, a crucial step in phagolysosome maturation, is driven by contact of Rab5a-positive vesicles with the phagosomal coat. We show that the sorting nexin SNX3 is transported with Rab5a vesicles and that its PX domain enables vesicle–phagosome contact by binding to PI(3)P in the phagosomal coat. Moreover, the C-terminal region of SNX3 recruits galectin-9, a lectin implicated in protein and membrane recycling, which we identify as a further regulator of phagosome compaction. SNX3 thus forms a hub for two distinct vesicle populations, constituting a convergence point for the endosomal recycling machinery, to contribute to phagosome m...

Dr. Derek Monette: Today's case is that of a 46-year-old male with recent diagnoses of Lyme disease and babesiosis who presented to our emergency department (ED) with abdominal pain, nausea, and diarrhea. The patient was previously healthy and had been well until approximately 2 weeks before the day of ED presentation, when he developed headache, fatigue, and myalgias. He also noticed that his right calf “looks sunburned,” and was warm to the touch. He was evaluated by his primary care physician (PCP) after 1 week of symptoms.

This study was aimed to know epidemiological aspects of Borrelia spp. in a protected urban area of Buenos Aires city, Argentina, where thousands of people visit this area for recreational purposes. Ticks were collected from vegetation, birds and dogs. Three hundred and forty birds belonging to 43 species, 41 genera, 18 families and six orders were captured (90.3% corresponded to the order Passeriformes). One hundred and twenty ticks were collected from 47 birds (13.8%) belonging to 10 species (23.2%), all of them from to the order Passeriformes (Emberizidae, Furnariidae, Parulidae, Thraupidae, Troglodytidae, Turdidae). Ticks were identified as Ixodes auritulus (56 larvae, 44 nymphs and 8 females) and Amblyomma aureolatum (1 larva and 11 nymphs).One thousand and ninety-one ticks collected f...

AbstractPurpose of ReviewElectronic health records (EHRs) are an excellent source of data for disease symptoms, laboratory results, and medical treatments. Thus, EHR data may improve the completeness of notifiable disease case reporting and enable longitudinal collection of disease data. The purpose of this review is to examine the current state of EHR use in public health infectious disease surveillance in the USA.Recent FindingsA wide variety of EHR data is used in infectious disease surveillance. EHR data were used to assess the incidence of Lyme disease and identify newly diagnosed HIV infections. EHR disease detection algorithms combined laboratory reports, diagnosis codes, and medication orders to identify cases and, in the case of Lyme disease, found incidence rates 4 –7 times hig...

In this study, B. burgdorferi-negative dogs were inoculated with B. turicatae, and seroconversion was confirmed by the rBipA (recombinant Borrelia immunogenic protein A) Western blot. Seropositive samples were tested with commercial and veterinary diagnostic laboratory B. burgdorferi-based tests. Borrelia turicatae-seroreactive samples cross-reacted with a whole-cell indirect fluorescent antibody (IFA) test and two multiantigen tests, but not with single-antigen tests using C6. Cross-reactivity with TBRF can confound epidemiology and surveillance efforts and confuse recommendations made by veterinarians for prevention and control. These findings demonstrate the need to critically evaluate results from B. burgdorferi diagnostic tests in the context of the assay type and the animal’s g...

Lyme disease is an infection caused by the spirochete Borrelia burgdorferi after it is transmitted to a mammalian organism during a tick blood meal. B. burgdorferi encodes at least 140 lipoproteins located on the outer or inner membrane, thus facing the surroundings or the periplasmic space, respectively. However, most of the predicted lipoproteins are of unknown function, and only a few proteins are known to be essential for the persistence and virulence of the pathogen. One such protein is the periplasmic BB0323, which is indispensable for B. burgdorferi to cause Lyme disease and the function of which is associated with cell fission and outer membrane integrity. After expression and transport to the periplasm, BB0323 is cleaved into C-terminal and N-terminal domains by the periplasmic...

Introduction: Acrodermatitis chronica atrophicans (ACA) is a late cutaneous manifestation of Lyme disease characterized by inflammatory lesions that slowly progress to atrophic plaques. The vast majority of ACA cases have been described in Europe and are associated to the genospecies Borrelia afzelii (B. afzelii). We hereby report the first case in Northern Mexico of ACA caused by locally acquired B. afzelii. (Source: Journal of the American Academy of Dermatology)

Malaria, Zika virus, West Nile virus, Dengue fever, and Lyme disease are common causes of morbidity and mortality around the world. While arthropod bites may cause local inflammation and discomfort, a greater concern is the potential to develop deadly systemic infection. Prevention of systemic infections by use of insect repellent (IR) constitutes one of the most critical aspects of public health efforts. Cost-effectiveness, availability, and high-efficacy against arthropod vectors are the key characteristics of an ideal IR. (Source: Journal of the American Academy of Dermatology)

Maintenance of Borrelia burgdorferi within its enzootic cycle requires a complex regulatory pathway involving the alternative factors RpoN and RpoS and two ancillary trans-acting factors, BosR and Rrp2. Activation of this pathway occurs within ticks during the nymphal blood meal when RpoS, the effector factor, transcribes genes required for tick transmission and mammalian infection. RpoS also exerts a ‘gatekeeper’ function by repressing 70-dependent tick phase genes (e.g., ospA, lp6.6). Herein, we undertook a broad examination of RpoS functionality throughout the enzootic cycle, beginning with modeling to confirm that this alternative factor is a ‘genuine’ RpoS homolog. Using a novel dual color reporter system, we established at the single spirochete level that ospA ...

Tick-borne relapsing fever (TBRF), characterized by recurring febrile episodes, is globally distributed and among the most common bacterial infections in some African countries. Despite the public health concern that this disease represents, little is known regarding the virulence determinants required by TBRF Borrelia during infection. Because the chromosomes of TBRF Borrelia show extensive colinearity with those of Lyme disease (LD) Borrelia, the exceptions represent unique genes encoding proteins that are potentially essential to the disparate enzootic cycles of these two groups of spirochetes. One such exception is a gene encoding an HtrA family protease, BtpA, that is present in TBRF Borrelia, but not in LD spirochetes. Previous work suggested that btpA orthologs may be important for ...

Authors: Serra V, Krey V, Daschkin C, Cafiso A, Sassera D, Maxeiner HG, Modeo L, Nicolaus C, Bandi C, Bazzocchi C Abstract Ixodes ricinus is the most common tick species parasitizing humans in Europe, and the main vector of Borrelia burgdorferi sensu lato, the causative agent of Lyme disease in the continent. This tick species also harbors the endosymbiont Midichloria mitochondrii, and there is strong evidence that this bacterium is inoculated into the vertebrate host during the blood meal. A high proportion of tick bites remains unnoticed due to rarity of immediate symptoms, implying the risk of occult tick-borne infections in turn a potential risk factor for the onset of chronic-degenerative diseases. Since suitable tools to determine the previous exposure to I. ricinus bites are...

The bacterial flagellar motor is a molecular machine that can rotate the flagellar filament at high speed. The rotation is generated by the stator-rotor interaction, coupled with an ion flux through the torque-generating stator. Here we employed cryo-electron tomography to visualize the intact flagellar motor in the Lyme disease spirochete,Borrelia burgdorferi. By analyzing the motor structures of wild-type and stator-deletion mutants, we not only localized the stator complexin situ, but also revealed the stator-rotor interaction at an unprecedented detail. Importantly, the stator-rotor interaction induces a conformational change in the flagella C-ring. Given our observation that a non-motile mutant, in which proton flux is blocked, cannot generate the similar conformational change, we pro...

The “Christmas tree” orientation of scaling lesions along the skin tension (Langer) lines in pityriasis rosea is well known. This pattern is best appreciated on complete examination of the trunk, in which the eruption follows the long axis of the V-shaped lines of the upper chest and back, emanating around the axillae, and running transversely along the abdominal wall and lower back. Secondary syphilis has a similar presentation. When patients present with asymptomatic, larger, nonscaling patches along Langer lines, another condition deserves diagnostic consideration.

CONCLUSIONS: While this study was unable to capture the military specific occupational exposure to I. scapularis, it does show a difference in period prevalence between service members and family members with the family members being at higher risk to contract Lyme instead of service members as is commonly suggested in the literature. Additional studies may be conducted to see if this holds true across service member Military Occupational Specialties as a proxy for occupational exposure. Similar studies should be conducted at military installations situated in Lyme endemic areas to determine if these results are comparable across the military or specific to West Point. Future research should attempt to identify all the service member protective factors against Lyme with attribution to perm...

BOSTON (CBS) – After more than a decade, experts are issuing new guidelines for the prevention and treatment of Lyme disease. Even though many of the recommendations are geared toward medical professionals, there are some key takeaways for the general public. Namely, the best way to protect yourself is to wear protective clothing and insect repellent with DEET and do frequent tick checks if you’ve been outdoors. Bathing within two hours of an outdoor activity can reduce the risk of Lyme disease. And if you have pets, you should check them regularly for ticks to prevent the ticks from falling off and reattaching to humans. If you are bitten by a deer tick, it’s engorged, and it has been attached for 36 hours or more, you should call your doctor or get to an urgent care fac...

We describe a 20-year-old woman with left seventh nerve palsy secondary to latent syphilis of unknown duration, with complete recovery after penicillin G benzathine. In addition to reactive rapid plasma reagin and positive T. pallidum particle agglutination testing, Lyme enzyme-linked immunosorbent assay was equivocal, and Lyme Western blot was positive for immunoglobulin M. In syphilis, Lyme enzyme-linked immunosorbent assay may be falsely positive, but Western blot is known to remain negative. Similarly, in LD, fluorescent treponemal antibody absorption testing may be falsely positive, but rapid plasma reagin remains nonreactive. Careful interpretation of these serologic tests is of utmost importance in differentiating between the 2, especially in areas with low prevalence of LD. (Source...

Authors: Conforti C, Vezzoni R, Retrosi C, Longone M, Corneli P, Magaton-Rizzi G, Nan K, Di Meo N, Zalaudek I Abstract Lyme disease is a tick-borne illness, which is tipically caused by Borrelia Burgdoferi. Over time, a typical Borreliosis skin reaction takes shape, i.e. the formation of an annular erythema that tends to expand centrifugally with erythematous edges whose diameter can reach up to 20 cm. The symptoms of Lyme disease are not only cutaneous but there may be a systemic involvement. Obviously, this disease can also affect pregnant women and for this reason this review aims to summarize the main ways of treatment to avoid worsening of the clinical condition in the mother and an eventual, albeit rare, involvement of the fetus.

Borrelia burgdorferi is a tick-borne bacterium responsible for approximately 300,000 annual cases of Lyme disease (LD) in the United States, with increasing incidences in other parts of the world. The debilitating nature of LD is mainly attributed to the ability of B. burgdorferi to persist in patients for many years despite strong anti-Borrelia antibody responses. Antimicrobial treatment of persistent infection is challenging. Similar to infection of humans, B. burgdorferi establishes long-term infection in various experimental animal models except for New Zealand White (NZW) rabbits, which clear the spirochete within 4 to 12 weeks. LD spirochetes have a highly evolved antigenic variation vls system, on the lp28-1 plasmid, where gene conversion results in surface expression of the antigen...

Monday 10 June 2019
Being outdoors during the warm weather season carries with it the risk of bites of all kinds – insects, animals, ticks and others. Here is some helpful advice for treating bites and itching. Check the symptoms. Most insect bites and stings are mild, causing minor symptoms like itching, redness, stinging or a small degree of swelling around the bite. In some rare cases, stings from hornets, bees, wasps, scorpions or fire ants may lead to more serious reactions, including mosquito-borne West Nile virus. The Mayo Clinic advises moving away from the area where you were stung or bitten to prevent further injury. Then, try to remove the stinger if needed, and wash the wound with soap and water. For tick bites, remove the tick immediately. The Cleveland Clinic says the longer a tick...

Bell’s palsy (BP) is a unilateral, acute facial paralysis that is clinically diagnosed after other etiologies have been excluded by appropriate history, physical examination and/or laboratory testing or imaging. Symptoms include abnormal movement of facial nerve. It can be associated with changes in facial sensation, hearing, taste or excessive tearing. The right and left sides are equally affected but bilateral BP is rare (0.3%). Paralysis can be complete or incomplete at presentation. All ages can be affected but there are increased risks in the 15-45 year age group and those with diabetes, immunodeficiency or are pregnant. Etiology is specif...

This meta-analysis suggests that when symptoms of the disease are confined to a localised skin infection, treatment failures are relatively infrequent, only 2% at 12 months. Effective antibiotics include penicillin V, doxycycline, azithromycin, cefuroxime, amoxicillin and ceftriaxone plus doxycycline.The research has significant limitations, but choice, dose and duration of antibiotics appear to have little impact on outcomes. This research does not suggest that guidelines need to be reviewed. (Source: Current Awareness Service for Health (CASH))

NEW YORK (AP) — U.S. health officials say a record number of tick-borne diseases were reported last year. The 2017 tally of more than 59,000 cases is a 22 percent increase from the previous year. The Centers for Disease Control and Prevention released the numbers Wednesday. Lyme disease accounted for nearly three-quarters of the illnesses. That's about 43,000 cases. Traditionally about 30,000 cases of Lyme disease were reported to the government each year, but experts believed there was underreporting and thought the actual number was more like 300,000. Experts say better reporting may be a reason for recent increases, but scientists have also discovered more diseases transmitted by ticks.

SCARBOROUGH, Maine (AP) — New England’s hot summer might be helping keep the ticks that carry Lyme disease at bay. The Northeastern states — which are some of the worst for Lyme in the U.S., posing a hazard to residents and vacationers alike — are still totaling the number of Lyme cases from the summer months, and there will likely be more in the fall. But preliminary indicators show the disease abating, and public health authorities are finding fewer deer ticks, state officials and researchers said. In Maine, there had been a steady annual growth of Lyme cases, including a jump of 23 percent to more than 1,850 last year. But the Maine Center for Disease Control and Prevention said Lyme cases for May, June and July were below long-term averages. Those are major months for i...

BOSTON (CBS) – More and more people are being afflicted by Lyme disease, not only here in New England but around the country. It begs the question, why don’t we have a vaccine to prevent this common tick-borne illness? A human vaccine was introduced in 1998. It was effective but expensive and there was public concern about its safety and sales were low, so it was yanked off the market four years later. Right now there is only a Lyme vaccine for dogs. Fortunately, there is a new vaccine for humans in the pipeline developed by a French company, which says it has received fast-track status from the FDA and hopes to get the vaccine licensed in about five years.

Discussion It can be difficult to consider what is the problem when a health care provider is presented with a group of seemingly disparate signs and symptoms with a history and time course that do not match classic (or commonly atypical) disease presentations. Common things happen commonly, so when symptoms occur without the usual co-occurring symptoms, unusual symptoms or time courses, it can be challenging. The provider must develop a reasonable differential diagnosis and balance how far to go with the evaluation against how much to monitor the patient for new signs or symptoms which can provide new information. Patient safety and the natural time course of diseases have to be considered. Providers also recognize that well-appearing individuals with acute onset of problems usually have ...

The 23-year old takes more medications than most 80-year-olds. “On a daily basis, I’m taking anywhere from 20 to 30 pills and then I do anywhere from two to four IV infusions per day,” says Emily. (WBZ-TV) Staying on top of all of her antibiotics, supplements, probiotics, and infusions was a real challenge until she was introduced to Medisafe. “Medisafe gives patients a tool, a medication management tool, to get their medications organized,” says Jon Michaeli, Medisafe Executive Vice Presid...

As it gets warmer and people start spending more time outside, I have more and more patients coming into my office and complaining of a “sun allergy.” A sun allergy is really a layman’s term, which refers to a number of conditions when a rash occurs on skin that has been exposed to the sun. These are also referred to as photosensitive disorders or photodermatoses, and can be broadly categorized into the following medical terms: idiopathic photodermatoses, exogenous photodermatoses, photoexacerbated dermatoses, genetic photodermatoses, and metabolic photodermatoses. Sounds complicated, right? A sun allergy refers to a number of conditions when a rash occurs on skin that has been exposed to the sun. Let’s break it down: If, after spending a few hours in...

This study shows strong evidence that Lyme disease-causing bacteria exist transiently in blood,” co-author Dr. Thomas Fritsche said in prepared remarks. “T2MR is the only technology proven sensitive enough to directly detect these bacteria.” Traditionally, researchers use serology to diagnose Lyme disease by detecting antibodies that are triggered by the disease. There is no FDA-approved diagnostic based on direct measurement of Lyme disease-causing bacteria. Regulatory agencies recommend a 2-tiered approach to diagnose Lyme disease, but the technique detects 2 antibodies that require 1-2 weeks and 4-6 weeks to reach detectable levels, leaving a window where diagnosis of early Lyme disease is not possible. T2MR detected both confirmed cases of Lyme disease tested in the s...

The University of Arkansas for Medical Sciences said Tuesday that Mark Smeltzer has been awarded $11 million in federal funding for Phase II of a program that supports microbiology and immunology research. Phase I of the Centers of Biomedical Research Excellence (COBRE) grant was awarded by the National Institutes of Health (NIH) in 2012 at $10 million. Phase II began May 1 and is $11 million. The first COBRE grant allowed Smeltzer to establish the UAMS Center for Microbial Pathogenesis and Host Inflammatory Responses. Its focus is pathogens – bacteria, viruses and microorganisms – and the disease responses they cause in humans. The latest award continues funding of the center, with individual projects on cancer, Lyme disease, pneumonic plague and chlamydial infection. Smeltzer...

“This year, there are worse ticks than many of us have ever seen in our lives,” says Janet Foley, an epidemiologist at the University of California Davis School of Veterinary Medicine. Ticks are roaming American forests in greater numbers this year than any in recent memory leaving thousands of humans at risk for lyme disease, say public health officials. And things could get much worse through the summer if weather conditions remain humid, spelling trouble for the people who roam in their habitat. The prevalence of ticks—and the diseases they carry—has been on the rise in recent decades as reforestation and climate change expanded the range of the eight-legged bacterial vectors. Public health officials have attributed the pervasiveness of ticks so far this year to ...

It took eight years of feeling rundown with flu-like symptoms before Jennifer was finally diagnosed with Lyme disease. “Basically lost the whole second half of my twenties to Lyme disease,” Jennifer explained. She was bedridden for months at a time, she had to quit her job, and move back in with her parents. “It was hard to get up a flight of stairs, I couldn’t empty the dishwasher, I mean basic tasks,” she said. Even after the official diagnosis and treatment Jennifer relapsed...

Tick season is upon us, and it’s shaping up to be a real doozy. Scientists predict 2017 will bear the highest number of ticks in recent years, with a jump in reported cases of tick-borne illnesses in some regions of the U.S. Ticks are thriving thanks to a recent explosion of the white-footed mice population, which carry Lyme disease, Powassan virus and other tick-borne illnesses. Meanwhile, warmer winters caused by climate change are allowing ticks to remain active longer and carry diseases into new regions of the U.S. Experts suggest people living in regions where these diseases are most prevalent ― the Northeast, mid-Atlantic and upper Midwest ― should learn about common tick misconceptions and best practices to avoid bites.

CBS Local – There are a few drawbacks to the calendar shifting to the summer months, like the influx of ticks and infections like Lyme Disease. Now doctors are cautioning of another, potentially fatal tick-borne disease: Powassan Virus. Powassan virus is even more serious than Lyme, as it causes inflammation to the brain. For the reported cases, 15 percent of those infected have died and another 50 percent have had some form of a neurological disability. As of right now, there’s no cure. Symptoms include fever, headache, vomiting, weakness, confusion, loss of coordination, speech difficulties and seizures. “About 15 percent of patients who are infected and have symptoms are not going survive,” Dr. Jennifer Lyons, chief of the division of neurological and inflamm...

When my son Dan was diagnosed with severe obsessive-compulsive disorder, his psychiatrist informed me and my husband that Dan was “borderline psychotic.” In other words, our son was out of touch with reality. For most people, psychosis usually presents in one of two ways: Hallucinations – consist of seeing, hearing or feeling things that are not actually there. A common example is hearing voices. Delusions – consist of beliefs that are not likely to be true and that seem irrational or nonsensical to other people. A typical example involves believing that outside forces are controlling your thoughts, feelings, and behaviors. At the time we were told of our son’s issues, my thoughts immediately turned to schizophrenia, as that is the illness typically associated with psychosis. A...

Discussion Inflammation of the middle layer of the eye, or uvea, is termed uveitis. Uveitis can be divided into anterior, intermediate or posterior uveitis by involving the anterior (iris and ciliary body), intermediate (vitreous) or posterior (choroid and usually retina) compartments. Panuveitis involves all 3 compartments. Duration can also be used to classify uveitis. Acute is 6 weeks and > 3 months is chronic persistent uveitis. Episodic periods of inactivity and reactivity that last more than 3 months are called recurrent uveitis. A third way to characterize uveitis is if it is granulomatous or not. Uveitis increases with age with the highest incidence and prevalence in > 65 year olds. Only ~10% of uveitis occurs in the pediatric age group. Uveitis can be difficult to identify i...

Global warming already widens the footprint of Lyme disease while Zika virus exacerbates asthma and lung diseases and increases the risks posed by violent weather and wildfires.

The study, published Monday in the BMJ Open Diabetes Research & Care, compared annual average temperatures across the United States from 1996 to 2009 with reported new cases of type-2 diabetes. The disease, which typically develops later in life, prevents the body from absorbing glucose needed to produce energy. In particularly hot years, the number of new diagnoses spiked. “When it gets warmer, there is higher incidence of diabetes,” Lisanne Blauw, the study’s co-author and a PhD candidate at the N...

Cases of Lyme disease in Michigan have risen dramatically in recent years, and a new study links that trend to larger and more widespread tick populations. Researchers collected data from the Michigan Department of Health and Human Services on 1,057 Lyme disease cases diagnosed between 2000 and 2014, and aligned them with a new analysis of tick distribution across the state. Results showed that not only did the number of yearly infections in the state increase significantly over the 15-year period, but so did the number of counties where ticks had been seen, or found to be established. And the number of infected people may be much higher than the records indicate, the researchers said. Because Lyme disease is frequently misdiagnosed as other illnesses, reported cases likely represent only ...

Discussion Japanese encephalitis virus (JEV) is a Flavivirae, arbovirus that is endemic to many areas of Asia and the Pacific. It is estimated to affect ~70,000 people/year with ~10-15,000 deaths yearly in 20 countries, with a fatality rate of 35-40%. It can cause encephalitis and irreversible neurological morbidity. JEV is spread by Culex mosquitos which feed on swine. Increased environmental temperature and increased humidity (warm air is more moist) increases mosquito numbers, their survivability and ultimate dissemination. China has the highest rates of JEV with particular areas being more prone, as some areas co-farm rice and swine and the families live closely to the rice paddies and livestock which encourages transmission. JEV’s range has expanded over the past few decades inc...

One of the key differences between the Mr Snell and Mr Nuttall is that only one of them is a local. While the UKIP leader recently moved to the constituency in order to contest it, Mr Snell has lived in the Potteries for the past 13 years. He is a former leader of the nearby Newcastle-under-Lyme council and has worked with UNISON since 2014 – first as an organiser and now as a manager for the West Midlands regio...

For hundreds of millions of years, ticks have survived on Earth by sucking blood from their victims for days, often leaving behind terrible diseases as a thank-you note. But no one has ever looked at why ticks, themselves, are able to survive while harboring bacteria, viruses and parasites. Now, for the first time, scientists have decoded how the ingenious tick immune system fights a myriad of microbes. (Source: ScienceDaily Headlines)

Discussion Fatigue is a subjective feeling of decreased energy, tiredness or feeling of exhaustion. Lethargy is often used synonymously, but lethargy is a state of being drowsiness or sleepy, and implies mental status changes. Both can cause the person to be apathetic or less active. Fatigue is a common state that almost everyone experiences multiple times in his or her lifetime. For most people it is a relatively acute or short-term chronic problem, often with a relatively easily identifiable problem cause, such as inadequate sleep, acute illness, or overexertion. For some, it can be less readily identifiable such as depression, anemia, or hypothyroidism or because of a chronic illness with its waxing and waning natural history or being under- or over-treated. Chronic fatigue and cause d...

(Reuters Health) – It may one day be possible to spot illness the same way many of us already track our exercise habits and sleep patterns: with wearable sensors, researchers say. In a new study, 60 people wore devices that collected more than 250,000 measurements a day on things like heart rate, oxygen in the blood, activity levels, calories expended, sleep patterns and skin temperature. After researchers got a baseline idea of normal readings for each person in the study, they looked for deviations from these typical patterns to see whether changes might be tied to new environmental conditions, illness, or other factors that can impact health. The goal is a health dashboard that does for people what dashboards already do for cars, said senior study author Dr. Michael Snyder, direct...

Henry Heimlich, the medical maverick who came up with a maneuver credited with saving thousands of choking victims but who damaged his standing as a proponent of the curative powers of malaria, died on Saturday at the age of 96. Heimlich, a doctor who developed a life-saving technique to dislodge airway blockages, died at Christ Hospital in Cincinnati of complications from a massive heart attack he suffered on Monday, his family said in a statement. A thoracic surgeon who often feuded with the established medical community, Heimlich said the maneuver which was named after him saved more than 100,000 lives. He claimed to have used it himself last May on another resident of the Cincinnati retirement home where he lived. “It made me appreciate how wonderful it has been to be able to sav...

SPECIAL FROM Next Avenue Whether it came on suddenly when you were playing tennis or more gradually over many years, knee pain can keep you from doing even the most basic of activities. At the very least, it can limit your ability to move as easily or quickly, or sit in one place for an extended time. Arthritis is the most common cause of knee pain for older adults, said Dr. Julie Switzer, an orthopedic surgeon at Regions Hospital in St. Paul, Minn. Arthritis comes in three main forms, she said: osteoarthritis, inflammatory arthritis and post-traumatic arthritis. We’ll examine these types, as well as other causes of knee pain, below. The others include Lyme arthritis, torn cartilage or ligament, tendinitis, bursitis, gout and spontaneous osteonecrosis of the knee. Then, we&...

People react very differently to an infection with the Borrelia bacterium that causes Lyme disease. Researchers have investigated this varying response, concluding that age, genetic disposition and previous Lyme infections play an important role. However, despite the large differences observed, the Borrelia bacterium has a clear effect on the immune system ’s energy regulation, opening up opportunities for research into better detection of Borrelia infections.
