Abstract

Kemerovo virus (KEMV) is a member of the Great Island virus genetic group, belonging to the tick-borne arboviruses of the genus Orbivirus within the family Reoviridae. Nine strains of KEMV, which were isolated from various locations in Russia, were sequenced by high-throughput sequencing to study their intraspecific diversity and the interspecific relationships of viruses within the Great Island genetic group. For the first time, multiple reassortment within KEMV was reliably demonstrated. Different types of independently emerged alternative reading frames in segment 9 and heterogeneity of the viral population in one of the KEMV strains were found. The hypothesis of the role of an alternative open reading frame (ORF) in segment 9 in KEMV cellular tropism was not confirmed in this study.
