Abstract

Carbapenem-resistant Enterobacteriaceae (CRE) only contaminated the environmental surfaces of rooms housing CRE colonized/infected patients infrequently (8.4%) and at low levels (average, 5.1 colony-forming units [CFU]/120 cm² per contaminated surface). Three species of CRE (Klebsiella, Enterobacter, and Escherichia) survived poorly (>85% die-off in 24 hours) when ~2 log10 CFU were inoculated onto 5 different environmental surfaces.

摘要

耐碳青霉烯类肠杆菌科细菌(CRE)仅偶尔(8.4%)且低水平(每个污染表面平均5.1个菌落形成单位[CFU]/120 cm²)污染CRE定植/感染患者病房的环境表面。当将约2 log10 CFU接种到5种不同环境表面时,三种CRE(克雷伯菌属、肠杆菌属和大肠埃希菌)存活能力较差(24小时内>85%死亡)。
