Porcine circovirus 3 (PCV3) is a recently emerged circovirus discovered in 2016 that has drawn the attention of the swine industry worldwide. In this study, we evaluated the genetic diversity of PCV3 strains on pig farms. A total of 261 samples from sows, weaning pigs, growing pigs, and stillborn/mummified fetuses were analyzed by quantitative real-time PCR. The results revealed that at least two main lineages of PCV3 are circulating in Brazil. For the first time, it was possible to detect the presence of two different PCV3 strains in the same host.
猪圆环病毒 3 型（PCV3）是一种于 2016 年新发现的圆环病毒，引起了全球养猪业的关注。本研究评估了猪场内 PCV3 毒株的遗传多样性。通过定量实时 PCR 分析了来自母猪、断奶仔猪、生长猪和死胎/木乃伊胎儿的 261 个样本。结果表明，至少有两个主要的 PCV3 谱系在巴西流行。首次在同一宿主中检测到两种不同的 PCV3 毒株的存在。
