Bats of the subtropical climate zone of the Krasnodar Territory of Russia as a possible reservoir of zoonotic viral infections

Abstract

Emerging and reemerging infections pose a grave global health threat. The emergence of the SARS-CoV-2 virus and the resulting COVID-19 pandemic have demonstrated the importance of studying of zoonotic viruses directly in natural foci. For SARS-like coronaviruses, as well as for many other zoonotic pathogens (including hemorrhagic fevers and rabies agents), the main reservoir are horseshoe bats (Rhinolophus spp.), which are widely distributed in Eurasia and Africa. Their range also covers the southern regions of Russia, including the North Caucasus and Crimea. Large colonies of these animals are located on the territory of Sochi National Park (SNP; subtropical zone of Krasnodar Territory, Greater Sochi region, North Caucasus). In total, according to long-term observations, up to 23 species of bats were registered here, including the great (Rh. ferrumequinum), the lesser (Rh. hipposideros), and the Mediterranean (Rh. euryale) horseshoe bats. This review provides information on zoonotic viruses associated with species of bats distributed in the subtropical zone of Krasnodar Territory of Russia, and analyzes their possible role as a natural reservoir of emerging and reemerging infections. Studying the circulation of zoonotic viruses in bats is an important element of monitoring viral populations in natural foci.
