Abstract

Porcine parvovirus 7 (PPV7) was first detected in Korean pig farms in 2017. The detection rate of PPV7 DNA was 24.0% (30/125) in aborted pig fetuses and 74.9% (262/350) in finishing pigs, suggesting that PPV7 is circulated in Korean domestic pig farms. Phylogenetic analysis based on VP amino acid sequences demonstrated that the nine Korean strains (PPV-KA1-3 and PPV-KF1-6) were closely related to that of previously reported US and Chinese PPV7 strains. In addition, the Korean strains have genetic diversity with insertion or deletion mutations. This study contribute to the understanding of the molecular epidemiology of PPV7 in Korea.
