Abstract
Porcine circovirus type 3 (PCV3) was initially reported in 2016 in the United States of America. Since then, the virus has been detected on swine farms in Poland, South Korea, and China using PCR. However, a serological survey of PCV3 in pig populations has never been conducted. In this study, for the first time, we established an indirect enzyme-linked immunosorbent (ELISA) assay and performed a national retrospective serological survey for PCV3. Our results showed that the PCV3-postive rate increased from 22.35% to 51.88% between 2015 and 2017. The above results suggest PCV3 has spread widely in China with increased positive rates since 2015.
