Novel lineages of human astrovirus (HAstV) types 2, 2c, and 2d have been identified. Upon sequencing of the 3' end of the genome, the type 2c and 2d HAstVs were found to be open reading frame 1b (ORF1b)-ORF2 recombinant, with ORF1b being derived from type 3 and type 1 HAstVs, respectively. An ORF2 interlineage recombinant strain, 2c/2b, was also identified.
新型人类星状病毒(HAstV)类型 2、2c 和 2d 已被鉴定。对基因组 3'端进行测序后发现,2c 和 2d 型 HAstV 为开放阅读框 1b(ORF1b)-ORF2 重组体,其中 ORF1b 分别来源于 3 型和 1 型 HAstV。还鉴定出一种 ORF2 谱系间重组株,2c/2b。
