[Lyme disease in Khabarovsk Territory]

The natural foci of Lyme's disease with the main vector Ix. persulcatus tick have been detected in Khabarovsk Territory. Five B. burgdorferi strains were isolated from the adult unfed ticks of this species, featuring 20% infection rate in the suburbs of Khabarovsk. A wide spread of the infection in this territory is demonstrated. The authors describe the typical pattern of early stages of serologically documented disease.
