Abstract

The MICs of penicillin and cefotaxime for a range of penicillin-susceptible and penicillin-resistant isolates of Streptococcus pneumoniae were unchanged by the addition of gentamicin. In time-kill studies the rate of killing was greater for 18 of 20 isolates in the presence of gentamicin. However, mean differences in killing after 6 h of incubation were modest, not exceeding 1 log10 unit.

摘要

对于一系列对青霉素敏感和耐药的肺炎链球菌分离株,加入庆大霉素后青霉素和头孢噻肟的最低抑菌浓度(MIC)没有变化。在时间-杀菌研究中,20株分离株中有18株在庆大霉素存在时的杀菌速率更高。然而,孵育6小时后的平均杀菌差异不大,不超过1个对数10单位。
