Detection of Porcine circovirus 3 from captured wild boars in Korea.

ABSTRACT: Porcine circovirus 3 (PCV3) is a newly discovered ssDNA virus. The virus was first reported in pigs suffering from several clinical syndromes, including porcine dermatitis and nephropathy syndrome, reproductive disorders, respiratory disease and myocarditis. PCV3 was recently reported in wild boars with high prevalence as well. In this study, 266 wild boar anal swab, feces, nasal swab and whole blood samples were collected from three mainland provinces and one island province (Chungbuk, Gangwon, Gyeonggi, Jeju) of South Korea between 2019 and 2020 including 119 from male, 142 from female and 5 undetermined. PCV3 was diagnosed targeting conserved rep (replication associated protein) gene region using Direct PCR and sequencing. Out of 266 tested samples, 15 were positive for PCV3 with detection frequency at 5.6%. Among 266 samples tested, we obtained 14 partial rep gene sequences and one complete genome sequence of PCV3 with a genome size of 2000nt. Here we present the evidence of PCV3 circulation in Korean wild boars.
