[Epidemiologic and clinical characteristics of Lyme borreliosis in northeastern Poland].

Lyme borreliosis (LB) caused the tick-borne spirochete B. burgdorferi, is associated with a wide variety of manifestations including dermatologic, rheumatologic, neurologic and cardiac abnormalities, that can differ from one region to another. To define clinical picture of LB in Poland, particularly in north-eastern region, we studied in 46 patients. Diagnosis of LB was established according to criterion, including serological confirmation with ELISA LB seems to be disease, which renal prevalence in Poland is higher, than it was primarily estimated. Clinical picture of the disease does not differ significantly from observed in other parts of the world. The only, but important exception is more frequent manifestation of B. burgdorferi infections with meningitis or/and encephalitis (48% of patients).
