湖南省部分地区奶牛源金黄色葡萄球菌分离鉴定与耐药性分析

Isolation,Identification and Drug Resistance Analysis of Staphylococcus aureus in Some Area of Hunan Province Dairy Cattle

[目的]为了解湖南省部分地区奶牛场金黄色葡萄球菌耐药情况,制定合理的用药方案,对来自湖南省不同地区的牛奶样品进行细菌分离与鉴定。[方法]得到19株金黄色葡萄球菌,分别进行药敏试验和耐药基因检测。[结果]试验结果显示,19株金黄色葡萄球菌均呈现多重耐药,其中对青霉素的耐药率较高,对万古霉素和利福平的耐药率极低,耐药基因的结果与耐药表现基本相同。[结论]试验结果可以为作为治疗湖南省奶牛场金黄色葡萄球菌感染提供依据。

[Objective] In order to find out the drug resistance of Staphylococcus aureus in dairy farms in Hunan province, a reasonable medication plan was developed to isolate and identify the bacteria in milk samples from different areas of Hunan province. [Method] Drug susceptibility test and drug resistance gene test were conducted on 19 strains of Staphylococcus aureus. [Result] The results show that: All 19 strains of Staphylococcus aureus showed multiple drug resistance. The drug resistance rate to penicillin was high, while the drug resistance rate to vancomycin and rifampicin was very low. [Conclusion] The results of drug resistance genes were basically the same as the resistance performance, which could provide a basis for the treatment of Staphylococcus aureus infection in dairy farms in Hunan province.
