A novel porcine circovirus 3 (PCV3) was first detected in pigs showing porcine dermatitis and nephropathy-syndrome, reproductive failure, and multi-systemic inflammation in the US. This is a report of PCV3 as a potential etiological agent of clinical signs, reproductive failure and respiratory distress on Korean pig farms, based on in situ hybridization, pathological, and molecular findings. Confirmation of the presence of PCV3 may be increased coinfection patterns with other causative agents of disease in Korean pig herds, indicating the need for further systemic investigation of pathogenicity and of multiple infections with PCV2 genotypes and bacteria, and development of an effective PCV3 vaccine.
