Abstract:
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.
