中文摘要：

从新疆昌吉、伊犁、石河子3个地区奶牛养殖场乳腺炎奶样中共分离134株金黄色葡萄球菌，对其中mecA基因阳性的30株进行了8种不同抗菌素敏感性检测。结果显示，分离自同一地区牛乳源耐甲氧西林金黄色葡萄球菌（MRSA）对不同药物的耐药性不同，不同地区牛源MRSA对同一药物的耐药性也存在差别。3个地区分离的牛源MRSA均对青霉素、氨苄西林表现为耐药。此外还发现，伊犁地区的所有菌株均对四环素敏感。该调查显示，新疆奶牛乳腺炎金黄色葡萄球菌中MRSA普遍存在，MRSA的分离率可达22．3％，且对当前常用的抗菌素呈现多重耐药现象。

英文摘要：

The mecA gene of 134 Staphyloccus aureus strains isolated from dairy cow ent regions of Xinjiang.Shihhotze, Yili and Changji was detected and susceptivity of 30 staphyloecus aureus strains to 8 different antibiotics were investigated in this study. Ou MRSA isolated from the same area has different antibiotic resistant profile, and MRSA ent area has different antibiotic resistance for the same antibiotics. The MRSA from all ant to penicillin and Ampicillin. All strains isolated from Yili area are sensitive to tetr mastitis in 3 differ- methicillin-resistant r result showed that isolated from differ- 3 areas were resist- indicated that MRSA is widely distributed in Xinjiang dairy cow mastitis and isolation rate is 22.3 %. The antibiotic resistance of MRSA in the three regions of Xinjiang is multidrug resistant.
