摘要
猪圆环病毒是能够引起猪的免疫抑制性疾病。现已鉴定出4个基因型。其中,PCV1无致病性,PCV2具有致病性,而PCV3和PCV4是近年来分离鉴定出的新的具有致病性基因型。本文对猪圆环病毒的生物学特征、诊断及防控进行阐述。
Porcine circovirus is an immunosuppressive disease of swine.Four genotypes have been identified.A-mong them,PCV1 is not pathogenic,PCV2 is pathogenic.PCV3 and PCV4 are new pathogenic genotypes isola-ted and identified in recent years.In this paper,the biological characteristics,diagnosis and control of porcine circovirus were described.
