First Record of Lyme Disease Borrelia in the Arctic

The epidemiology and ecology of Lyme disease is very complex, and its reported geographical distribution is constantly increasing. Furthermore, the involvement of birds in long distance dispersal and their role as reservoir hosts is now well established. In this study, we have shown that sea birds in the Arctic region of Norway carry Ixodes uriae ticks infected with Lyme disease Borrelia garinii spirochetes. Interestingly, DNA sequencing showed that these isolates are closely related to B. garinii previously isolated from birds, as well as from clinical specimens in northern Europe.

I don't know--- are the Faeroe Islands in the Arctic?

J Clin Microbiol. 1999 Apr;37(4):890-6.

Isolation of Lyme disease Borrelia from puffins (Fratercula arctica) and seabird ticks (Ixodes uriae) on the Faeroe Islands.

Departments of Microbiology, Umeâ University, S-901 87 Umeâ, Sweden.

This is the first report on the isolation of Lyme disease Borrelia from seabirds on the Faeroe Islands and the characteristics of its enzootic cycle. The major components of the Borrelia cycle include the puffin (Fratercula arctica) as the reservoir and Ixodes uriae as the vector. The importance of this cycle and its impact on the spread of human Lyme borreliosis have not yet been established.

Borrelia spirochetes isolated from 2 of 102 sampled puffins were compared to the borreliae previously obtained from seabird ticks, I. uriae. The rrf-rrl intergenic spacer and the rrs and the ospC genes were sequenced and a series of phylogenetic trees were constructed. Sequence data and restriction fragment length polymorphism analysis grouped the strains together with Borrelia garinii.

In a seroepidemiological survey performed with residents involved in puffin hunting on the Faeroe Islands, 3 of 81 serum samples were found to be positive by two commonly used clinical tests: a flagellin-based enzyme-linked immunosorbent assay (ELISA) and Western blotting. These three positive serum samples also had high optical density values in a whole-cell ELISA.

The finding of seropositive Faeroe Islanders who are regularly exposed to I. uriae indicate that there may be a transfer of B. garinii by this tick species to humans.

I think they aren't but I'm not very well in geography.

halfway between England and Iceland; so they are on an important Arctic migratory route but not in the official Arctic.

would be interesting to know if there are clear cases of lyme disease there ... come to think of it, maybe they can dig up some 50 or 100 year old puffins from the ice and test them for Bb DNA? That would maybe answer the question if the spreading is due to better testing or for real (probably both, but still ...). With improved sequencing and testing techniques one might even be able to backtrack all these borrelia species to the original source of the problem (that would be interesting because of the rumours about military involvement in the 70/80-ies or possibly longer ago).

Abstract: Foreldrar tveggja ára hrausts drengs leituðu á bráðamóttöku barna. Fjórum vikum áður var barnið bitið af blóðmaur (e. ixodes tick) í Danmörku. Viku fyrir komu fékk drengurinn útbrot á handleggi og síðar komu fram útbrot á fótleggjum. Meðferð með Econazolum (Pevaryl®) að ráði barnalæknis var árangurslaus. Drengurinn hafði ekki önnur einkenni. Hann var hitalaus og líkamsskoðun var ómarkverð utan útbrota á hand- og fótleggjum (mynd 1 og mynd 2). Hver er líklegasta sjúkdómsgreiningin?

automatic translation of the abstract:
Parents of two years of healthy boy came to the emergency department of children. Four weeks before the baby was bitten by an ant blood (e. ixodes tick) in Denmark. A week before the boy got a rash on arms and later observed a rash on the legs. Treatment with Econazolum (Pevaryl ®) at the recommendation of a pediatrician was ineffective. The boy had no other symptoms. He had no fever and physical examination was ómark prices outside of rash on the arms and legs (Figure 1 and Figure 2). What is the most likely diagnosis?
