Conditions of the taiga tick (Ixodes persulcatus) population in Cherepovets

The research presents some facts on seasonal activity of Ixodes persulcatus in the tourist-recreational area of the “Green Grove” in Cherepovets and Vologda Region. A procedure of Ixodes persulcatus harvesting was carried out by standard methods during the months of April through September in 2015. The number of ticks collected from the flag and the check-man on the route of one kilometer was taken into account. The types of tick species and their gender were determined in laboratory conditions. The determination of infectious agents was carried out by the Real Time PCR method, kit of “AmpliSens® TBEV, Borrelia burgdorferi sl, Anaplasma phagocytophillum, Ehrlichia chaffeensis / E. Muris-FL”. The evaluation was conducted on the basis of the Center of Hygiene and Epidemiology of Vologda Region. Conditions of the population of I. Persulcatus in the tourist- recreational area of the “Green Grove” located in the city limits of Cherepovets are characterized by the high seasonal activity and by the high level of infected ixodids.
