Abstract
INTRODUCTION Bastroviruses were discovered in the Netherlands in 2016 in human stool samples and show partial genetic similarities to astroviruses and hepatitis E viruses. Their association with disease onset has not yet been established. MATERIALS AND METHODS Metagenomic sequencing of fecal samples of Nyctalus noctula bats collected in the Russian Federation in 2023 was performed. Two almost complete genomes of bastroviruses were assembled. The zoonotic potential of these viruses was assessed using machine learning methods, their recombination was studied, and phylogenetic trees were constructed. RESULTS A nearly complete bastrovirus genome was de novo assembled in one of the samples, and it was used to assemble another genome in another sample. The zoonotic potential of the virus from one of these samples was estimated as high. The existence of recombination between structural and non-structural polyproteins was demonstrated. CONCLUSION Two bastrovirus genomes were assembled, phylogenetic and recombination analyses were performed, and the zoonotic potential was evaluated.

Abstract
Aichi virus C, a species in the genus Kobuvirus, causes diarrhea diseases in pigs and goats and pose health threat and economic loss for stock farming. A nearly complete genome sequence of caprine kobuvirus GCCDC14 was obtained from an anal swab of a black goat died from diarrhea collected in Hubei, China in 2019. Phylogenetic analyses suggested that GCCDC14 is a novel genotype of Aichi virus C, forming a sister branch to other caprine kobuviruses, with P1 and VP0 genes more closely related to porcine kobuviruses and VP3 in an independent branch. Compared to previous caprine kobuviruses, unique amino acid changes in the poly-l-proline type II helix structure of VP0 and VP1 were found, which may affect the cellular machinery of host and pathogenicity. This study indicates the presence of the kobuvirus with continuously evolving features and emphasizes the surveillance and genetic evolution investigation of kobuviruses for safety of husbandry.
