【摘要】 [目的]对陕西宝鸡地区的20头健康奶牛和20头患子宫内膜炎奶牛生殖道内微生物区系进行研究。[方法]采用常规的细菌分离鉴定方法。[结果]健康奶牛乳酸杆菌、产乳酸球菌和表皮葡萄球菌的分离率明显高于患病奶牛的分离率,差异显著(P<0.05);大肠埃希菌、金黄色葡萄球菌、链球菌的分离率分别低于患病奶牛,差异显著(P<0.05).[结论]产乳酸细菌、表皮葡萄球菌是健康奶牛生殖道微生物区系的优势菌群,奶牛子宫内膜炎的致病菌以大肠埃希菌、金黄色葡萄球菌和链球菌为主。由于产乳酸细菌减少导致生殖道的微生物区系紊乱是奶牛子宫内膜炎发病的重要诱因.更多还原

【Abstract】 Objective In order to determine the vaginal microflora,40 postpartum cows were choosed and divided into 2 groups.Methods Take a routine method of classification and determination of bacterium. Results The results of experiment indicated that the most frequently isolated bacteria were Lactobacillus Lactococcus S.epidermidis in heathy cows and the ratio of isolation was obviously higher than that from endometfitis cow(P<0.05).But the ratio of isolation of Staphylococcus,Streptococcus,Escherichia.coli were lower than that from endometritis cows(P<0.05).Conclusions Lactobacillus and S.epidermidis were the predominants in the vagina of heathy cows,but Staphylococcus,Streptococcus and Escherichia.coli were the predominants in endometritis cows.The decrease of lactic acid bacillus and the increase of condition pathogen bacillus are the most important inducement of cows’ endometritis.更多还原
