Twenty strains of Staphylococcus aureus isolated from patients with endocarditis were examined in vitro for susceptibility to rifampin, nafcillin, and vancomycin and to combinations of rifampin with nafcillin or vancomycin. Minimum bactericidal concentrations of rifampin ranged from 0.0031 to 0.0125 mug/ml, of nafcillin ranged from 0.078 to 0.312 mug/ml, and of vancomycin ranged from 0.312 to 1.25 mug/ml. The combination of rifampin with nafcillin was synergistic for 12 strains; the combination of rifampin plus vancomycin was synergistic for 5 of the isolates.
对从心内膜炎患者中分离出的20株金黄色葡萄球菌进行了体外试验,检测其对利福平、萘夫西林和万古霉素以及利福平与萘夫西林或万古霉素联合用药的敏感性。利福平的最低杀菌浓度范围为0.0031至0.0125微克/毫升,萘夫西林的最低杀菌浓度范围为0.078至0.312微克/毫升,万古霉素的最低杀菌浓度范围为0.312至1.25微克/毫升。利福平与萘夫西林联合用药对12株菌株具有协同作用;利福平加万古霉素联合用药对5株分离株具有协同作用。
