猪细小病毒的分型、遗传进化及流行病学研究进展

Types,genetic evolution and its epidemiology of porcine parvovirus

猪细小病毒(PPV)是影响母猪繁殖性能,尤其是初产母猪的重要因素。目前,已经比较明确细小病毒具有复杂的生活史;其分型为PPV-4型、博卡病毒和PPV5-6型。不仅家猪和野猪感染PPV,而且多种动物体内存在PPV的特异性抗体,因此PPV的宿主范围在扩大,感染谱逐渐加宽。本综述将为PPV的预防、诊断和治疗提供借鉴。

Porcine parvovirus （PPV） is one of factors which lead to the reproductive performance failure of sows, especially the first farrowing sows. Now there is a relatively clear life history of parvovirus. PPV were divided into PPV1-4, porcine boca-like virus （PBo-likeV） and PPVS-6. Not only pig and wild boar infected with PPV, but also the antibodies against PPV were detected in many other animals. So, the host range of PPV was enlarged and the spectrum of infection was gradually widened. This review will be beneficial to the prevention, diagnosis and treatment of porcine parvovirus,
