Epidemiology and Genetic Characterization of Porcine Parvovirus 7 Recovered from Swine in Hunan, China.

ABSTRACT: Porcine parvovirus 7 (PPV7) was first discovered in swine in 2016, and PPV7 infection has been detected in aborted pig fetuses and in sows that experienced reproductive failure. The objective of this study was to report the prevalence and genetic characterization of PPV7 in Hunan, China. Seventy of the four hundred and twenty-two (16.6%) serum, semen, and tissue samples collected from pigs were positive for PPV7. One complete PPV7 strain and eighteen complete cap gene sequences were obtained; nucleotide and amino acid identity among the nineteen Cap sequences were 88.1-99.4% and 88.1-100%, respectively. They shared identity with previously discovered sequences ranging from 86.6 to 98.9% and 83.7 to 99.8% at the nucleotide- and amino acid-level, respectively. The phylogenetic tree an
