A total of 450 samples from domestic pigs in China were tested for porcine parvoviruses (PPVs) and co-infections with porcine circovirus type 2 (PCV2), and their complete capsid genes were sequenced. The prevalence of PPV1, PPV2, PPV3, PPV4, and PCV2 was 5.56 %, 39.56 %, 45.11 %, 21.56 %, and 47.33 %, respectively, and co-infection with PCV2 occurred in 4 % (PPV1), 22.44 % (PPV2), 24 % (PPV3), and 12 % (PPV4) of the samples. Phylogenetic analysis revealed two main lineages for each virus, and residues that differentiated these viruses were identified. The co-infections of emerging PPVs and PCV2 were prevalent, indicating their cooperative roles in porcine circovirus-associated diseases.
对来自中国家猪的450份样本进行了猪细小病毒（PPV）检测以及与猪圆环病毒2型（PCV2）的共感染检测，并对其完整的衣壳基因进行了测序。PPV1、PPV2、PPV3、PPV4和PCV2的流行率分别为5.56%、39.56%、45.11%、21.56%和47.33%，4%（PPV1）、22.44%（PPV2）、24%（PPV3）和12%（PPV4）的样本发生了与PCV2的共感染。系统发育分析揭示了每种病毒的两个主要谱系，并鉴定出区分这些病毒的残基。新出现的PPV与PCV2的共感染很普遍，表明它们在猪圆环病毒相关疾病中起协同作用。
