摘要
目的:研究不同配比的头孢噻肟/舒巴坦及头孢噻肟单剂对临床分离菌体外抗菌作用。方法:采用平皿二倍稀释法测定头孢噻肟/舒巴坦对180株临床分离菌的最低抑菌浓度(MIC)、最低杀菌浓度(MBC)。结果:头孢噻肟/舒巴坦(1∶1,2∶1)对180株临床分离菌具有广谱抗菌作用,对革兰阴性杆菌MIC90为0.25～32 mg.L-1,是头孢噻肟单剂的1/4～1/8,明显强于头孢噻肟单方使用效果,同时也强于头孢噻肟/舒巴坦(4∶1,8∶1)。结论:1∶1及2∶1配比的头孢噻肟/舒巴坦对绝大多数临床感染细菌有很强的抗菌活性,明显优于头孢噻肟单剂和头孢噻肟/舒巴坦其他配比。
Objective： To study the in vitro antibacterial activities of cefotaxime and cefotaxime/sulbactam （CTX/SBT） with different proportions. Method ： The minimal inhibitory concentrations （MIC） and the minimal bactericidal concentrations （MBC） were measured in 180 clinical isolates. Result： CTX/SBT with proportion of 1：1 and 2：1 both displayed potent and broad - spectrum antibacterial activities against 180 clinical isolates irt vitro, which were better than CTX and CTX/SBT with proportion of 4：1 and 8： 1. MIC90 of CTX/SBT （ 1 ： 1 and 2：1 ） against gram-negative bacteria was 0.25 - 32 mg · L- 1, which was 1/4 - 1/8 of that of cefotaxime. Conclusion： CTX/SBT with proportion of 1：1 and 2：1 shows promising antibacterial activities against the major clinical isolates with better effect when compared with cefotaxime and cefotaxime/sulbactam with the other proportions.
