Routine surveillance revealed that the prevalence of P[4] rotaviruses circulating in children with acute diarrhea in Guangxi Province, China, increased in 2014. However, VP7 genotyping for these P[4] rotaviruses was unsuccessful. Exhaustive database searching and sequence analysis indicated that the G genotype of these P[4] rotaviruses was G2, and the VP7 genes clustered with recently emerging G2 strains in several countries within an emergent evolutionary lineage that was distinct from the previously designated lineages I-IV as well as lineage V including porcine rotaviruses. Further studies are essential to monitor the potential global spread of this emerging G2 rotavirus.
常规监测显示,2014年中国广西壮族自治区急性腹泻患儿中流行的P[4]型轮状病毒感染率有所上升。然而,对这些P[4]型轮状病毒进行VP7基因分型未获成功。通过详尽的数据库检索和序列分析表明,这些P[4]型轮状病毒的G基因型为G2,其VP7基因与近期在多个国家出现的G2毒株聚集在一个新出现的进化谱系中,该谱系不同于先前指定的I - IV谱系以及包括猪轮状病毒在内的V谱系。进一步的研究对于监测这种新出现的G2型轮状病毒在全球的潜在传播至关重要。
