从宁夏地区部分奶牛场采集164份患有乳房炎奶牛的乳样，采用 VITEK-2全自动微生物鉴定系统进行病原菌的分离鉴定，共分离鉴定出放射根瘤菌30株，分离率高于奶牛乳房炎常见的病原菌溶血葡萄球菌、巴氏杆菌、金黄色葡萄球菌等；15种抗菌药物的药敏试验结果表明，放射根瘤菌对阿莫西林、林可霉素、先锋霉素Ⅴ、头孢曲松已产生不同程度的耐药性，而其他磺胺类、氨基糖苷类、喹诺酮类、头孢类中的11种药物则表现出较好的抑菌效果。

164 milk samples were collected from cow mastitis cases which broke out in Ningxia area.Then i-solated pathogenic bacteria were identified by VITEK-2 automatic microbial identification system.The de-tection results showed that 30 strains of Rhizobium radiobacter were isolated and identified,and the isola-tion rate was higher than that of usual pathogenic bacteria which led to cow mastitis,such as Staphylococ-cus haemolyticus ,Pasteurella and Staphylococcus aureus .The results of drug sensitivity test to 15 kinds of antibacterial drugs showed that the isolated Rhizobium radiobacter already had different resistance de-gree to amoxicillin,lincomycin,cephalosporin V and ceftriaxone.Meanwhile,we also found that other 11 drugs which belong to sulfanilamide groups,aminoglycosides,quinolones and cephalosporins displayed good antibacterial effects.
