The minimal inhibitory concentrations of piperacillin and seven other betalactam antibiotics were determined against 407 bacterial isolates. Piperacillin was found to be more active than ampicillin against susceptible gram-negative bacilli and more active than either carbenicillin or ticarcillin against Pseudomonas aeruginosa and streptococci. Although piperacillin was active against Klebsiella pneumoniae, this activity was less than that of the cephalosporins. Piperacillin was not active against penicillin-resistant Staphylococcus aureus and Enterobacteriaceae that were resistant to the other test antibiotics.
测定了哌拉西林和其他七种β-内酰胺类抗生素对407株细菌分离株的最低抑菌浓度。结果发现,哌拉西林对敏感革兰氏阴性杆菌的活性比氨苄西林更强,对铜绿假单胞菌和链球菌的活性比羧苄西林或替卡西林更强。尽管哌拉西林对肺炎克雷伯菌有活性,但其活性低于头孢菌素。哌拉西林对耐青霉素金黄色葡萄球菌和对其他受试抗生素耐药的肠杆菌科细菌无活性。
