Abstract

Synergy time-kill studies against 40 methicillin-resistant Staphylococcus aureus (MRSA) strains of differing resistance phenotypes were conducted. Subinhibitory concentrations of telavancin were combined with sub-MIC concentrations of other antimicrobial agents that might be used in combination with telavancin to provide Gram-negative coverage. The highest incidence of synergy was found after 24 h with gentamicin (90% of strains), followed by ceftriaxone (88%), rifampin and meropenem (each 65%), cefepime (45%), and ciprofloxacin (38%) for combinations tested at or below the intermediate breakpoint for each agent.

摘要

对 40 株不同耐药表型的耐甲氧西林金黄色葡萄球菌(MRSA)菌株进行协同时间杀伤研究。替考拉宁的亚抑菌浓度与其他抗菌药物的亚 MIC 浓度联合使用,这些药物可能与替考拉宁联合使用以提供革兰氏阴性菌覆盖。在 24 小时后,与氨基糖苷类药物(90%的菌株)、头孢曲松(88%)、利福平、美罗培南(各 65%)、头孢吡肟(45%)和环丙沙星(38%)联合使用时,协同作用的发生率最高,这些组合均低于每种药物的中介折点。
