Clinical and research data indicate that low-level infection in animals, including people, may persist despite antibiotic therapy. In dogs, standard antibiotic doses and treatment for 4 wk have been demonstrated to be effective. If clinical signs recur, the antibiotics mentioned above can be used again, because persistent infection is not the result of acquired antibiotic resistance. Prolonged antibiotic therapy (>4 wk) may be beneficial for animals with continuing disease signs.

These symptoms are typically intermittent.
