Story summary
  • Researchers identify the BYN7 strain of bovine norovirus (BNoV) in the GIII.2 group.
  • Phylogenetic analysis shows BYN7 has low similarity to existing sequences and implies new gene sequences.
  • Bovine rotavirus classification reveals BRVH clusters, with BRVH closer to human rotaviruses.
  • Two bovine coronavirus (BCoV) genomes were sequenced, showing similarity to Zhejiang and Xinjiang strains.
  • Recombination analysis indicates potential genetic exchange between BCoV and human coronaviruses and signals cross-species transmission risk.
