[Molecular-genetic characterization of the Bhanja virus (BHAV) and the Razdan virus (RAZV) (Bunyaviridae, Phlebovirus) isolated from the Ixodes ticks Rhipicephalus bursa (Canestrini and Fanzago, 1878) and Dermacentor marginatus (Sulzer, 1776) in transcaucasus].
Two bunyaviruses, Bhanja (BHAV, LEIV-Az1818) isolated from the Ixodes ticks Rhipecephalus bursa (Canestrini and Fanzago, 1878) in Azerbaijan (1973) and Razdan (RAZV; strain LEIV-Arm2741) isolated from the Dermacentor marginatus (Sulzer, 1776) ticks in Armenia (1972), were de novo sequenced (on the Illumina platform). The amino acid identity between these viruses proteins were 95.8% (RdRp, L-segment), 90.3% (GnGc, M-segment), and 92.5% (N, S-segment). Thus, RAZV was classified to BHAV group. ⋯ BHAV LEIV-Az1818 is most closely related to the Indian strain BHAV IG690 (99%), while showing 90% identity with the European BHAV isolates. The genome structure of BHAV and RAZV is typical of the tick-transmitted phleboviruses. Based onthe result of the molecular-genetic and phylogenetic analysis RAZV has been classified as belonging to BHAVgroup in the genus Phlebovirus (Bunyaviridae).
