乳房炎是奶牛最常见的疾病之一,金黄色葡萄球菌是导致奶牛乳房炎的重要细菌之一。为了调查宁夏地区规模牧场金黄色葡萄球菌在奶牛中的流行情况和耐药特点。本研究通过流行病学调查、常规微生物学及PCR鉴定方法,对宁夏地区6 个规模牧场中的856 份奶样中的病原微生物进行分离鉴定和耐药性分析。结果表明,856 份奶样中,共获得467 株金黄色葡萄球菌,阳性率为55%;分离株对头孢噻肟、丁胺卡那霉素、阿莫西林、庆大霉素、万古霉素、环丙沙星、链霉素高度敏感。
Mastitis is one of the most common diseases in dairy cows,and Staphylococcus aureus is one of the important bacteria which can cause mastitis.To investigate the prevalence and drug resistance characteristics of Staphylococcus aureus in dairy cows in large-scale pastures in Ningxia. In this study,the pathogenic microorganisms in 856 milk samples from 6 large-scale ranches in Ningxia were isolated, identified and analyzed for drug resistance through epidemiological investigation,routine microbiology and PCR identification methods. The results showed that in 856 milk samples,a total of 467 strains of Staphylococcus aureus were obtained with a positive rate of 55%;the drug susceptibility results showed that the isolates were highly sensitive to cefotaxime,amikacin,amoxicillin,gentamicin,Vancomycin,ciprofloxacin and streptomycin.
