title: [Genetic diversity of ixodid tick-borne pathogens in Tomsk City and suburbs].
abstract: We studied two urban and two suburban biotypes of Tomsk City for tick-transmitted diseases prevalence in naturally collected ticks. Tick-borne encephalitis virus (TBEV) was found in 6.5% of tick samples, West Nile virus (WNV) in 2.2%, Borrelia spp. in 8%, Rickettsia spp. in 2.5%, and Ehrlichia spp. in 1.7% of samples. Genetic markers of Powassan virus, Bartonella spp., and Balbesia spp. were not found. Analysis of the genetic diversity of revealed pathogens resulted in the following conclusions: 1. TBEV strains belong to Siberian and Far-Eastern subtypes, and Far-Eastern subtype of TBEV is most frequent in urban biotypes (up to 43 % of urban strains of TBEV); 2. WNV strains belong to genotype la; 3. Borrelia spp. were classified as B. garinii; 4. Rickettsia spp. were classified as R. tarasevichiae and probably as a new Rickettsia raoultii subspecies; 5. Ehrlichia spp. were classified as E. muris. The coexistence of several pathogens was found in 5.7% of tick samples, and the most frequent combination was TBEV + Borrelia spp.
