The first report of porcine parvovirus 8 detection and genetic analysis in South Korea

= 45), PRRSV 2 was the most frequent (33.3%, 15/45), followed by PRRSV 1 (22.2%, 10/45) and PCV2 (8.9%, 4/45). Samples positive for all three viruses were also identified (6.7%, 3/45). Whole-genome sequencing of representative samples revealed two genetically distinct clades circulating in Korea, which exhibited amino acid differences in predicted antigenic epitopes of the VP1/VP2 region. These findings suggest that PPV8 is already widespread in Korean pig farms and should be considered as part of routine diagnostic surveillance in herds experiencing endemic viral infections.
