Phylogenitc analysis and immunogenicity comparison of porcine genotype G9 rotavirus in China from 2020-2023.

ABSTRACT: As an emerging genotype, the G9 genotype rotaviruses (RVs) are widespread among humans and pigs, and have been reported in many countries and regions in the recent years. Moreover, porcine G9 strains could cross the interspecies barrier to infect human. To investigate the epidemic trends of porcine G9 strains as well as the cross-immunoreactivity among different isolates, an epidemiological investigation about porcine G9 genotype RVs (PoRVs) was performed during the period 2020-2023 in multiple provinces of China. A total of nine representative strains were identified. The phylogenetic analysis based on viral VP7 gene showed that these strains mainly clustered with lineages III and VI, which revealed the predominant G9 PoRVs in China. Moreover, a new lineage, lineage VII, was identified, a
