A phylogenetic tree constructed by the unweighted pair group method with arithmetic means (UPGMA) for the VP8* gene from 13 human and two feline rotavirus strains possessing the AU-1 gene 4 allele revealed that these strains could be classified into two clusters which did not correspond with the year of isolation or the host species from which they originated. Nine of 10 human strains and one feline strain isolated in Japan formed one cluster, whereas three human strains from Italy and one feline strain from Australia formed the other. Human strain K8 from Japan was distantly related to the Australo-European clustering.
采用算术平均非加权配对组方法（UPGMA）构建了13株人源和2株猫源轮状病毒株VP8*基因的系统发育树，这些病毒株均具有AU-1基因4等位基因，结果显示这些病毒株可分为两个簇，这两个簇与分离年份或病毒起源的宿主物种均不对应。在日本分离的10株人源病毒株中的9株和1株猫源病毒株形成一个簇，而来自意大利的3株人源病毒株和来自澳大利亚的1株猫源病毒株形成另一个簇。来自日本的人源病毒株K8与澳欧聚类关系较远。
