Abstract

From 2006 to 2011, in the Tomsk region (south of Western Siberia), eight species of pathogens were detected in birds and the ticks feeding on them: Tick-borne encephalitis virus (TBEV), West Nile virus (WNV), Borrelia spp., Rickettsia spp., Bartonella spp., Anaplasma spp., Ehrlichia spp., and Babesia spp. The identification of a number of strains of viruses and bacterial genovariants related geographically with the Russian Far East, Eastern Siberia, China and Japan and confirms the possibility of the role of birds in the spread of pathogens in the direction of Western Siberia and back. Most of the species that breed and migrate in Western Siberia are of Eastern origin and mostly fly for wintering to South-East Asia. Among these species in our samples, Phylloscopus proregulus was a carrier of both TBEV and Bartonella spp.; Luscinia calliope were infected with both TBEV and Borrelia, while Tarsiger cyanurus were infected with WNV.
