Porcine parvovirus (PPV) 1 is a major causative pathogen of reproductive failure and PPV2–6 were recently identified as newly emerging viruses with unknown pathogeneses. In this study, we examined 926 samples from domestic pig farms for the presence of PPV1–6 co-infection. The prevalence of PPV1–6 was significantly greater in the lung tissue samples than in the aborted pig fetus samples. PPV3–6 were detected for the first time in Korean domestic pigs, and concurrent infections were more common than single infections in the pig population with numerous infectious pathogens such as PPV. Furthermore, the Korean PPV1 strain (PPV1-82) was identical to the virulent PPV-27a strain in this study. These results describe, for the first time, the prevalence of PPV1–6 in South Korean domestic pigs.
