摘要:牛病毒性腹泻(BVD)是以发热、腹泻、黏膜糜烂或溃疡为主要特征的一种接触性传染病,牛传染性鼻气管炎(IBR)是一种急性、热性、接触性传染病。这两种病均为OIE规定的应通报疫病,均呈世界性分布,对全球范围内的畜牧业危害极大,造成了严重的经济损失,对其进行及时准确的检测诊断至关重要。根据规模化养殖场的疫病防控需求,对来源于不同地区的送检样品分别用ELISA和荧光PCR方法进行牛病毒性腹泻和牛传染性鼻气管炎的检测。结果发现牛病毒性腹泻的阳性率为2.43%(n=494),牛传染性鼻气管炎的阳性率为3.68%(n=598)。为养殖场了解疫病的流行情况以及这两种疫病的防控提供参考。38793 毕业论文关键词:牛病毒性腹泻;牛传染性鼻气管炎;ELISA;荧光RT-PCR
Detection of Bovine Viral Diarrhea and Infectious Bovine Rhinotracheitis
Abstract: Bovine viral diarrhea (BVD) is a contact infectious disease characterized by fever, diarrhea and mucosal erosion, infectious bovine rhinotracheitis (IBR) is a kind of highly fatal and contagious disease. These two diseases are required to be informed by OIE regulations, they are distributed worldwide, having great harm on global animal husbandry, and result in serious economic losses, so rapid and accurate detection and diagnosis are essential. According to the needs of large-scale farms, bovine viral diarrhea and bovine infectious rhinotracheitis are tested by ELISA and fluorescence PCR methods for samples from different regions. The positive rate of bovine viral diarrhea is 2.43% (n=494), and the positive rate of bovine infectious rhinotracheitis is 3.68% (n=598). These results may provide a reference for the farms to know the epidemic situation and the prevention and control of these two diseases.
