From June to July 2017, six Seneca Valley virus (SVV) strains were isolated from swine herds exhibiting SVV-associated porcine idiopathic vesicular disease (PIVD) in Guangdong province, China. Complete genomic sequences of these six newly identified strains were genetically and phylogenetically analysed. The results revealed that these six SVV strains were genetically closely related to USA/GBI29/2015 and notably distinct from all previous Chinese strains, indicating the reemergence of new SVV strains in Guangdong province.
2017 年 6 月至 7 月，从中国广东省出现 SVV 相关猪特发性水疱病（PIVD）的猪群中分离到 6 株 SVV 毒株。对这 6 株新鉴定的毒株进行了全基因组序列的遗传和系统进化分析。结果表明，这 6 株 SVV 株在遗传上与美国/GBI29/2015 株密切相关，与以往中国分离株明显不同，表明新的 SVV 株在中国广东省重新出现。
