Multiple exposures with cefotaxime in either Mueller-Hinton broth or cerebrospinal fluid had no effect on killing or the duration of postantibiotic effect (PAE) in Escherichia coli strains tested. However, upon multiple exposures in Mueller-Hinton broth, ciprofloxacin and gentamicin PAEs significantly decreased with a concomitant reduction in bacterial killing. A reduction in bacterial killing following multiple ciprofloxacin and gentamicin exposures was also seen with cerebrospinal fluid; however, the PAE was maintained.
在穆勒-欣顿肉汤或脑脊液中多次使用头孢噻肟对所测试的大肠杆菌菌株的杀菌效果或抗生素后效应(PAE)持续时间均无影响。然而,在穆勒-欣顿肉汤中多次使用后,环丙沙星和庆大霉素的PAE显著降低,同时细菌杀灭率也随之下降。在脑脊液中多次使用环丙沙星和庆大霉素后,细菌杀灭率也出现下降;不过,PAE得以维持。
