[DNA detection of pathogens transmitted by Ixodid ticks in blood of small mammals inhabiting the forest biotopes in Middle Irtysh Area (Omsk Region, West Siberia)].

Microtine rodents were captured in two disconnected sampling sites in Omsk region where Ixodes pesulrcatus and Ixodes trianguliceps are sympatric. In blood samples of rodents the DNA was revealed belonging to several ixodid-transmitted pathogens: Borrelia burgdorferi sensu lato (prevalence 20.0 and 6.0%, here and further values are given for the first and second site, respectively), Borrelia miyamotoi (8.3 and 2.0%), Anlaplasnma phagocytophilum (33.3 and 48.0%), Ehrlichia muris (30.0 and 2.0%) and Babesia microti (33.3 and 42.0%). Three genetic groups of A. phagocytophilhm based on 16S rRNA gene and groESL operon, as well as two genetic groups of B. microti, B. microti 'US'-type and B. microti 'Munich'-type, were detected.
