[Isolation of a Tahyna-like virus (Bunyaviridae, Bunyavirus, California encephalitis complex) on northern Sakhalin Island].

The strain LEIV-11483 Sak of Tahyna virus or a virus closely related to it antigenically was isolated from Aedes spp. mosquitoes (predominantly A. communis) collected August 25, 1985, in the light coniferous subzone of the mid-taiga landscape zone in the north of Sakhalin Island (54 degrees N, 142 degrees E). Altogether, 17.8 thousand mosquitoes were examined which were collected in June-August, 1985, in the light and dark coniferous subzones of mid-taiga. In the human population, virus-neutralizing antibodies to Tahyna virus were found in 7-18%, to Batai virus in 3%, to Uukuniemi virus in none.
