Abstract

MICs and MBCs of five beta-lactams , i.e. ticarcillin, azlocillin, piperacillin, cefsulodin and ceftazidime for 20 strains of Pseudomonas aeruginosa were studied with inocula ranging from 10(3) to 10(9) CFU/ml. Each antibiotic exhibited an inoculum effect at 10(5)-10(7) CFU/ml. However, ticarcillin had smaller MIC and MBC increments than the four other drugs, making it more suitable in certain cases.

摘要

研究了替卡西林、阿洛西林、哌拉西林、头孢磺啶和头孢他啶这五种β-内酰胺类抗生素对20株铜绿假单胞菌的最低抑菌浓度(MIC)和最低杀菌浓度(MBC),接种菌量范围为10³至10⁹CFU/ml。每种抗生素在10⁵ - 10⁷CFU/ml时均表现出接种量效应。然而,替卡西林的MIC和MBC增量比其他四种药物小,在某些情况下更适用。
