The tick-borne encephalitis (TBE) virus has been confirmed by molecular analysis in the Caucasus region for the first time. The virus obtained from a tick Ixodes ricinus ex Caspian green lizard belongs to the Zausaev strain of the Siberian subtype (not to a strain of the European subtype highly distributed in the territories adjacent to the Caucasus). This unusual record indicates the need to study the role of lizards in the circulation of natural focal infections.
