摘要
牛病毒性腹泻病毒(BVDV)引起牛病毒性腹泻-黏膜病,广泛分布于世界各地。该病毒具有较大的变异性,根据病毒基因组结构特点分为2个基因型,即BVDV1和BVDV2。每个基因型包括多种基因亚型,每个基因型又有2个生物型,致细胞病变(CP)型和非致细胞病变(NCP)型。病毒的这种特性造成各病毒株的抗原性和血清学特性的差异,给疫病的流行病学研究、诊断、疫苗研究和防控工作造成一定困难。文章论述了病毒的这种特性造成疫病的多种临床表现,导致疫病防控困难,说明了流行病学分析在该病防制的重要性,提出疫病主要诊断方法及防控措施。
Bovine viral diarrhea virus（BVDV） leads to BVD-MD,which prevails worldwide. BVDV has two genotypes BVDV1 and BVDV2 for its great variation based on the virus gene,and each type includes many subtypes and two biotypes, CP and NCP. The characteristics lead to great different antigenecity and serology among viruses. The review discussed the traits of virus and several clinical phenomena, which made more difficulity to prevent and control the disease,and advanced diagnostic methods and prevent and control measures.
