[Genetic characterization of new Komandory virus (KOMV; Bunyaviridae, Phlebovirus) isolated from the ticks Ixodes uriae, collected in guillemot (Uria aalge) nesting sites on Komandorski islands, the Bering sea].
Unclassified virus named Komandory virus (KOMV) isolated in Komandorski islands from the ticks Ixodes uriae in 1986 was partially sequenced. The KOMV nucleocapsid (N) protein sequence shows 30-40% identity level with the mosquito-borne phleboviruses and 43% with the Uukuniemi virus (UUKV) group (Phlebovirus, Bunyaviridae). ⋯ The KOMV RdRp identity with the Manawa virus reaches 74%, while showing 63% level at average with the other UUKV group viruses. According to the results of molecular-genetic and phylogenetic analysis, the KOMV is a new member of the UUKV group (Phlebovirus, Bunyaviridae).

[The taxonomy of the Baku virus (BAKV; Reoviridae, Orbivirus) isolated from the birds obligate parasites Argasidae ticks in Azerbaijan, Turkmenistan, and Uzbekistan].
The Baku virus (BAKV) was originally isolated from the ticks Ornithodoros capensis Neumann, 1901 (Acari: Argasidae) collected from the seagull (Larus argentatus) seating nests on the islands of the Baku archipelago, the Caspian sea. BAKV was assigned to Kemerovo group (KEMV) (Orbivirus, Reoviridae). The BAKV was frequently isolated from the ticks O. coniceps Canestrini, 1980, collected from L. argentatus and tern (Sterna hirundo) nests in Turkmenia and pigeon (Columba livia neglecta) nests in Uzbekistan. ⋯ The maximum identity level of the T2 protein (64.8%) is observed for the tick-borne viruses of the GIV (KEMV) group. According to the conducted molecular-genetic and phylogenetic analysis, the BAKV is a novel species of the genus Orbivirus. It forms a phylogenetic group distinctly related to the GIV group.
