摘要
大肠杆菌是严重危害牦牛养殖业的重要疾病,由于其血清型复杂和抗生素的大量使用所导致耐药菌株不断增加,对肠道正常菌群造成不良影响,给防制工作带来了巨大的困难和影响。据统计,该病在西藏牦牛中的发病率为10.1%,死亡率为2.5%,致死率为45.0%。西藏农牧学院动物科学学院曾群辉课题组对牦牛大肠杆菌的生物学特性进行了深入研究。所研制出的牦牛大肠埃希氏菌多价油佐剂甲醛灭活疫苗具有良好的免疫原性,对预防该病奠定了基础。
Yaks,Escherichia coli is the serious damage disease to the breeding yak,By the complex serotype andantibiotics were used, drug-resistant strains increase ,also bring the adverse effects for yak intestinal normal bacterium,to control and yaks health brings great difficulties and influence. According to the statistics, this disease incidence rate was 10.1%, mortality rate was 2.5%, death rate was 45.0%.College of Agriculture and Animal Husbandry Zeng Qun Hui Research Group to research the biological characteristics of Yaks, Escherichia coll. Have developed preparation yaks Escherichia coli polyvalent oil - adjuvant inactivated vaccine response a good immunogenieit, The vaccine laid the foundation for the prevention of the disease.
