During an 8-month period, 858 gram-negative aerobic rods resistant to carbenicillin (minimum inhibitory concentration, >/=128 mug/ml) were isolated. Susceptibility testing of 233 of these suggested that piperacillin might be active against more of these organisms than would carbenicillin or ticarcillin.
在8个月的时间里,分离出了858株对羧苄西林耐药(最低抑菌浓度≥128μg/ml)的革兰氏阴性需氧杆菌。对其中233株进行的药敏试验表明,哌拉西林对这些菌株的抗菌活性可能比羧苄西林或替卡西林更强。
