Porcine parvovirus 7 (PPV7), a new serotype of the porcine parvovirus, was discovered in swine of the USA in 2016. Recently, PPV7 was detected in Anhui province, China. Twenty-four of the 120 lung samples were PPV7-positive. Three PPV7 strains were sequenced and named PPV7/China/AHbz, PPV7/China/AHhf, and PPV7/China/AHmas, respectively. The complete genome and NS1 gene nucleotides of the three PPV7 strains showed 80.0%-98.4% and 94.4%-98.7% sequence identity, respectively, to the other PPV7 strains obtained from NCBI. The three PPV7 strains from Anhui share a common origin with a PPV7 GX49 strain isolated in Guangxi. These results help to understand the molecular epidemiology of PPV7.
猪细小病毒 7 型（PPV7）是一种新的猪细小病毒血清型，于 2016 年在美国猪群中发现。最近，在中国安徽省也检测到了 PPV7。从 120 个肺组织样本中检测到 24 个呈 PPV7 阳性。对 3 个 PPV7 分离株进行了测序，并分别命名为 PPV7/中国/AHbz、PPV7/中国/AHhf 和 PPV7/中国/AHmas。3 个 PPV7 分离株的全基因组和 NS1 基因核苷酸与从 NCBI 获得的其他 PPV7 株分别显示 80.0%-98.4%和 94.4%-98.7%的序列同一性。安徽的这 3 个 PPV7 分离株与广西分离的 PPV7 GX49 株具有共同的起源。这些结果有助于了解 PPV7 的分子流行病学。
