ABSTRACT
Porcine circovirus type 3 (PCV3) is a new member of Circovirus, which could cause various symptoms in infected pigs. It has been reported in many countries and detected from various animals. This study retrospectively analyzed serum samples that were randomly collected from 1,499 clinically healthy cattle in Shandong province from 2011 to 2018. The PCV3 DNA was detected in 28.95% (434/1,499) of samples. Twenty-seven cap genes of PCV3 were sequenced and compared with seventy reference sequences. They were in several different branches, but all belonged to PCV3b. The results indicated that PCV3 was prevalent in health cattle in Shandong province of China. Though infected cattle did not show any clinical symptoms, they could be a reservoir for the virus and probably transferred them back to pigs.
