A comparative analysis of the virus infection carrier state and distribution of genetic types of the virus of tick-borne encephalitis (TBE) among invertebrates (2 species of ticks, Ixodes persulcatus Schulze and Ixodes pavlovskyi Pomerantsev 1946) and vertebrate reservoir hosts (4 species of small rodents: the red vole Myodes rutilus Pallas, gray-sided vole Myodes rufocanus Sundevall, field mouse Apodemus agrarius Pallas, birch mice Sicista betulina Pallas and 1 species of insectivores - common shrew Sorex araneus L (1758)), dominating on the territory of the Novosibirsk region in 2009-14 years, was performed with the use of virological and molecular biological methods. Frequency detection of RNA and / or E protein in mammals (70,9 ± 3,0%) were shown to considerably exceed levels of virus infection carrier state rate of ticks (3,4 ± 0,4). In the circulation of three major types of TBE - Far East (FE), Siberian (NIB) and European (Eur) in natural populations in mono - or polytype forms in mites Sib type prevailed (p
