Abstract:

This study aimed to investigate the molecular and genetic characteristics of bovine enteroviruses (BEV) and further explore their features and molecular epidemiology. Five pairs of specific primers were designed to amplify and sequence the full-length genomes of the BEVHeN-B78 (EV-E) and HeN-YR91 (EV-F) strains using PCR. After sequencing, the full genomes were assembled, proofread, and analyzed for homology. The results showed that BEVHeN-B78 genome was 7 453 nt long, with a coding region of 6 523 nt, a 5' untranslated region (UTR) of 812 nt, and a 3'UTR of 118 nt. The HeN-YR91 genome was 7 460 nt, with a coding region of 6 502 nt, a 5'UTR of 825 nt, and a 3'UTR of 133 nt. Homology analysis showed that the HeN-B78 strain shared 75.9% to 88.0% similarity with species E, while HeN-YR91 shared 74.6% to 82.4% similarity with species F. Phylogenetic analysis of the whole genome and the VP1-VP4, 2B, 2C, and 3A-3D gene regions, confirmed that the HeN-B78 strain clustered with EV-E and the HeN-YR91 strain with EV-F. In conclusion, this study confirms the presence of bovine enterovirus species E and F in cattle farms in Henan Province, contributing valuable data to GenBank database of BEV in China.
