The MICs of imipenem and piperacillin, alone and in combination, against Pseudomonas aeruginosa were determined in a checkerboard titration microdilution assay. A dramatic, one-way antagonism of imipenem for piperacillin was demonstrated in 28 of the 35 strains examined; antagonism was associated with the induction of a beta-lactamase.
在棋盘滴定微量稀释试验中测定了亚胺培南和哌拉西林单独及联合使用时对铜绿假单胞菌的最低抑菌浓度(MIC)。在所检测的35株菌株中,有28株显示出亚胺培南对哌拉西林具有显著的单向拮抗作用;这种拮抗作用与β-内酰胺酶的诱导有关。
