Tick-borne infections are the most common group of zooanthroponotic diseases in the Northern Hemisphere. For the  Baltic Sea region and Fennoscandia, the dominant infectious pathologies transmitted by ticks are tick-borne borreliosis and tick- borne encephalitis. The presence of vast forested areas, actively  visited by people in St. Petersburg and the Leningrad region,  contributes to a rather high level of encroachment on the flares and  intelligence of the borreliosis and tick-borne encephalitis among the  population of these regions. The relatively dangerous pathogens that can be transmitted with the tick bite are also of particular danger:  Anaplasma sp., Ehrlichia sp., Coxiella burnetii, Rickettsia sp. In this  work, detection was performed using molecular genetic methods of  TBE virus, B. burgdorferi sensu lato and Rickettsia sp. in engorged  ticksple, as well as questing ticks collected from vegetation. The established levels of infection of TBE on infected ticks, levels of infection by pathogenic Borrelia of questing and engorgeded ticks  were approximately equal. Rickettsia was not found in the ticks. The  conducted analysis of the pathogens prevalence in comparison with  the data of russian and foreign authors. Monitoring the prevalence of tick-borne pathogens is an important issue in the prevention of tick- borne infections in the North-Western Russia.
