保定市奶牛子宫内膜炎细菌分离鉴定和药敏试验

Isolation,identification and drug sensitivity test of pathogenic bacteria of dairy cow endometritis in Baoding

为查明保定市奶牛子宫内膜炎主要致病菌,进而筛选敏感性药物,从保定市6个区县14个奶牛场中选取76头子宫内膜炎奶牛,无菌收集子宫分泌物样本,进行细菌分离鉴定和药敏试验。结果表明保定市奶牛子宫内膜炎主要病原菌为金黄色葡萄球菌、链球菌和大肠埃希菌;单一致病菌感染率为18.4%,多致病菌混合感染率为77.6%;诺氟沙星、氟苯尼考、新霉素、头孢西丁、头孢噻肟对主要致病菌高度敏感。

In order to find out the main pathogenic bacteria of endometritis in Baoding dairy cows and screen sensitive drugs,76 dairy cows with endometritis were selected from 14 dairy farms in 6 districts and counties of Baoding.Uterine contents were collected aseptically,and bacterial isolation,identification and drug sensitivity tests were carried out.Results showed that the main pathogenic bacteria of cow endometritis in Baoding were Staphylococcus aureus,Streptococcus and Escherichia coli.The infection rate of single pathogenic bacteria was 18.4%,and the mixed infection rate of multiple pathogenic bacteria was 77.6%.Norfloxacin,florfenicol,neomycin,cefoxitin and cefotaxime are highly sensitive to major pathogenic bacteria.
