Porcine circovirus associated diseases (PCVAD) have multiple manifestations that have been attributed to porcine circovirus type 2 (PCV2). Recently, a novel porcine circovirus, PCV type 3 (PCV3), was identified in pigs with systemic inflammation of unknown etiology. In this study, we tried to detect the PCV3 genome in tissue samples collected from Japanese pig herds in 2016. The PCV3 genome was detected by PCR in 7 of 73 samples. The homology between each Japanese strain was 99.5% for the full-length sequence and 98.9 to 99.2% for the open reading frame 2. These results suggest that PCV3 has already invaded Japanese pig farms.
猪圆环病毒相关疾病（PCVAD）有多种表现形式，这些都归因于2型猪圆环病毒（PCV2）。最近，在病因不明的全身性炎症猪中发现了一种新型猪圆环病毒，即3型猪圆环病毒（PCV3）。在本研究中，我们试图检测2016年从日本猪群采集的组织样本中的PCV3基因组。通过PCR在73份样本中的7份中检测到了PCV3基因组。各日本毒株之间的全长序列同源性为99.5%，开放阅读框2的同源性为98.9%至99.2%。这些结果表明PCV3已经侵入了日本的养猪场。
