摘要
本研究评估了青霉素 MIC 是否能预测粪肠球菌对哌拉西林的敏感性。在 427 株菌株中,有 10 株对哌拉西林产生耐药性。即使青霉素 MIC 值为 4-8 µg/mL 的菌株也可能表现出耐药性。这些研究结果表明,即使青霉素 MIC 值在易感范围内,也可能显示出对哌拉西林的耐药性,这对 CLSI 的指导方针提出了挑战。
Minimum inhibitory concentration of penicillin as a surrogate for in vitro piperacillin susceptibility of ampicillin-susceptible Enterococcus faecalis
This study evaluated whether penicillin MICs can predict piperacillin susceptibility in Enterococcus faecalis. Among 427 strains, 10 were resistant to piperacillin. Even strains with penicillin MICs of 4-8 µg/mL may exhibit resistance. These findings suggest that even penicillin MICs within the susceptible range may indicate piperacillin resistance, challenging CLSI guidelines.
