Porcine parvovirus (PPV) causes reproductive failure in sows and has spread worldwide. Several new types of porcine parvoviruses have recently been identified in pig herds. The prevalence of five porcine parvoviruses in the Chiangmai area of Thailand was studied. The prevalence in 80 pigs was 53% for PPV (PPV-Kr or -NADL2 being the new abbreviations), 83% for PPV2 (CnP-PARV4), 73% for PPV3 (P-PARV4), 44% for PPV4 (PPV4), and 18% for PBo-likeV (PBoV7). Over 60% of the pigs carried more than three of the five porcine parvoviruses and occurrence together of the two pairs of viral genes, PPV1/PPV3 and PPV2/PBo-likeV were observed. Phylogenetic analyses for PPV2 and PPV3 indicated the existence of only two major clades of PPV2 and one major clade of PPV3.
猪细小病毒（PPV）可导致母猪繁殖失败，且已在全球范围内传播。最近在猪群中发现了几种新型猪细小病毒。研究了泰国清迈地区五种猪细小病毒的流行情况。在80头猪中，PPV（PPV-Kr或-NADL2为新缩写）的流行率为53%，PPV2（CnP-PARV4）为83%，PPV3（P-PARV4）为73%，PPV4（PPV4）为44%，类PBo病毒（PBoV7）为18%。超过60%的猪携带五种猪细小病毒中的三种以上，并且观察到PPV1/PPV3和PPV2/类PBo病毒这两对病毒基因同时出现。对PPV2和PPV3的系统发育分析表明，PPV2仅存在两个主要分支，PPV3存在一个主要分支。
