用K -B纸片扩散法测定金黄色葡萄球菌对常用抗生素的体外敏感性。结果 6 36株金黄色葡萄球菌对青霉素G和氨苄青霉素的耐药率最高 ,分别为 93.4%和 90 % ;甲氧西林、复达欣、氧氟沙星、氟哌酸、复方新诺明的耐药率分别在 70 .2 %～ 79% ;氯霉素、庆大霉素、舒普深、阿米卡星的耐药率依次为 6 8.2 %、6 6 .4%、6 6 %和5 5 .4% ,耐药率较低的是利福平 (11.8% ) ,仅万古霉素无 1株耐药。提示金黄色葡萄球菌的耐药性日益严重 ,应在不同地区开展细菌耐药性监测 ,强调合理应用抗生素
In vitro susceptibility of Staphylococcus aureus to commonly used antibiotics by K-B disk diffusion method. Results The resistant rates of 6 strains of Staphylococcus aureus to penicillin G and ampicillin were the highest (93.4% and 90%, respectively). The methicillin, diphenxin, ofloxacin, norfloxacin and cotrimoxazole The resistance rates of chloramphenicol, gentamicin, shuopunshen and amikacin were in the order of 62.2%, 66.4% and 66%, respectively 5.54%. Rifampicin (11.8%) with lower resistance rate and no drug resistance with vancomycin alone. Suggesting that the drug resistance of Staphylococcus aureus is increasingly serious, should be carried out in different areas of bacterial drug resistance monitoring, emphasizing the rational use of antibiotics
