摘要
通过对奶牛子宫内膜炎主要致病菌的分离鉴定,揭示了大庆地区该病的主要致病菌并为临床上治疗奶牛子宫内膜炎提供依据。以大庆地区周边6个奶牛场56头子宫内膜炎患牛为研究对象,对子宫内容物进行细菌的分离鉴定,分离到细菌共计142株,其中30.25%的菌种具有溶血性,52.6%的菌种对实验动物具有致病性。该病84%为细菌的混合感染,主要由大肠杆菌、葡萄球菌、链球菌组成。结果表明大庆地区奶牛子宫内膜炎的主要致病菌为大肠杆菌、葡萄球菌、链球菌,且多为混合感染。
The composition of pathogenic bacteria endometritis was studied in dairy cows to find the main pathogen and prudence for the clinical treatment. 56 dairy cows affected endometritis were studied which bacteria were isolated and identified from contents of the uterus.142 bacterial isolates were obtained, 30.25% were hemolytic and 50.8% were pathogenic to experimental animals.84% of the diseases were commixed infected by E.coli, staphylococcus, streptococcus.The results showed that E.coli,staphylococcus, streptococcus were major pathogenic bacteria, and mostly commixed infected.
