Abstract

In a mouse model, ertapenem inhibited the anaerobic intestinal microflora and promoted overgrowth of enterococci, whereas imipenem-cilastatin had no effect on the indigenous microflora. Ertapenem, but not imipenem-cilastatin, promoted modest overgrowth of vancomycin-resistant enterococci when exposure occurred during treatment. Neither agent promoted colonization with extended-spectrum beta-lactamase-producing Klebsiella pneumoniae.

摘要

在小鼠模型中,厄他培南抑制肠道厌氧微生物群并促进肠球菌过度生长,而亚胺培南 - 西司他丁对原生微生物群无影响。在治疗期间暴露时,厄他培南而非亚胺培南 - 西司他丁会促进耐万古霉素肠球菌适度过度生长。两种药物均未促进产超广谱β-内酰胺酶的肺炎克雷伯菌的定植。
