广东一奶牛场临床乳房炎致病菌分离及其药敏试验

Pathogen Isolation and Drug Sensitive Test from Cows with Clinical Mastitis in one Dairy Farm in Guangdong

为了解广东某牛场奶牛乳房炎的细菌感染情况及其对常用药物的敏感性,本试验对从8头临床乳房炎患牛采集的8份奶样中分离细菌,纯化、鉴定后再进行药敏试验。结果表明,8份奶样中分离出3株大肠杆菌、5株金黄色葡萄球菌和3株链球菌。其中分离得到的大肠杆菌和链球菌对硫酸头孢喹肟最敏感,金黄色葡萄球菌对复方氨苄西林和阿莫西林同样敏感。本试验可为临床乳房炎治疗用药提供参考。

In order to observe the prevalence of cattle mastitis pathogens and sensitivity to commonly used drugs8 clinical mastitis milk samples were purified, pathogen isolated, identified and drug sensitivity tested. The results indicated that three strains of Escherichia coli, 5 strains of Staphylococcus aureus and 3 strains of Streptococcus were isolated. Escherichia coli and Streptococcus were the most sensitive to cefquinome sulfate, Staphylococcus aureus was equally sensitive to Compound Ampicillin and amoxicillin. This study can provide the theory basis for clinical mastitis treatment.
