The Kurkino and Sochi viruses of species Orthohantavirus dobravaense (ODOB) are among the pathogens that cause hemorrhagic fever with renal syndrome in the European part of Russia. However, the current literature provides limited data on the distribution of genetic variants of the ODOB in Russia. The aim is to identify ODOB in several regions of Volga, Central and Ural Federal districts of the Russian Federation and analyze their genome.Total RNA was isolated from lung tissue samples of striped field mouse (Apodemus agrarius) and yellow-necked mouse (A. flavicollis) captured in a number of areas of the Volga Federal District and neighboring regions in 2015-2023. Orthohantavirus RNA was detected by RT-PCR using specific primers to ODOB. The PCR amplification products were separated in agarose gel, purified, and subjected to Sanger sequencing. Comparative and phylogenetic analyses were performed for the sequenced genome fragments.Orthohantavirus RNA was detected in one sample of A. flavicollis from the Ulyanovsk region. Based on the analysis of the nucleotide sequences of the sequenced PCR products, it was found that the highest values of similarity were obtained when comparing the identified strain with the reference Kurkino virus from the Tula region. The data from the phylogenetic analysis of the sequenced fragment of the S and M segments allowed us to establish that the identified isolate is closely related to the Kurkino virus found earlier in A. agrarius in the Tula region. Thus, the detected isolate was identified as variant of Kurkino virus, which is also widespread in the central regions of Russia, Wetern Siberia and close related to genome variants that are distributed in Central Europian countries.It is proved for the first time that: 1) the range of Orthohantavirus dobravaense (Kurkino virus) extends to a part of the territory of the Volga Federal District; 2) Orthohantavirus dobravaense (Kurkino virus) and Orthohantavirus puumalaense (Puumala virus) are co-circulating in the Ulyanovsk region.
