[Complete genome analysis of the Batai virus (BATV) and the new Anadyr virus (ANADV) of the Bunyamwera group (Bunyaviridae, Orthobunyavirus) isolated in Russia].

Almost complete nucleotide sequences for the S, M, and L segments were obtained for three strains of the Batai virus (Bunyamwera serogroup, genus Orthobunyavirus, Bunyaviridae family). Based on the results of the phylogenetic analysis conducted forthe three genomic segments LEIV Ast507 and LEIV-Ast528 strains were grouped with other European BATV isolates and were found to be almost identical to the strain 42 isolated from Volgograd Region, Russia, 2003. Surprisingly, LEIV-13395 strain isolated from the Aedes sp. mosquitos in Magadan Oblast, 1987, turned out to be a novel genotype inside Bunyamwera serogroup. The highest nucleotide identity levels of LEIV-13395 genomicsegments (86.9%, 80.8%, 79.7% for S, M and L segments respectively) were observed with corresponding segments of the Batai virus.
