摘要 引起牛病毒性腹泻/黏膜病(bovine viral diarrhea—mucosal disease,BVD—MD)的病原为牛病毒性腹泻病毒(Bovine viral diarrhea virus,BVDV),牛感染后会出现与其他腹泻病相似的症状,仅通过临床表现和病理观察很难做出准确鉴别;其次持续感染(PI)牛是该病主要传染源,如何鉴别、净化牛场中PI牛十分重要。为了检测BVDV病原和净化PI牛,选择一种最佳的检测方法非常重要。文章对目前常用的不同BVDV检测方法进行了比较分析。不同检测方法在敏感性、特异性等方面均存在差异。实际应用时应根据检测目的综合考虑,选择适宜的检测方法。 The pathogen that causes bovine viral diarrhea-mucosal disease(BVD-MD)is Bovine viral diarrhea virus(BVDV),and the infected cattle will have symptoms similar to other diarrhea diseases It is difficult to make accurate identification only through clinical manifestations and pathological observations;secondly,persistently infected cattle(PI)cattle are the main source of infection of the disease,and how to identify and purify PI cattle in cattle farms is very important.In order to detect BVDV pathogens and purify PI cattle,it is very important to choose an optimal detection method.The article compares and analyzes the different BVDV detection methods commonly used at present.Different detection methods have differences in sensitivity and specificity.In actual application,the appropriate detection method should be selected according to the comprehensive consideration of the detection purpose.
