【摘要】 <正>Background Group A rotavirus(RVA)is the leading cause of acute gastroenteritis in children worldwide.RVA G9 has been recognized as the fifth most predominant G genotype spreading throughout the world.Phylogenetic analyses for the VP7(G)genes demonstrate that most of G9rotaviruses circulating in children belong to lineage III.However,the first G9 rotavirus strain T203identified in China belongs to lineage VI which includes most of porcine G9 rotaviruses around更多还原
