Carbapenem-resistant Enterobacteriaceae: frequency of hospital room contamination and survival on various inoculated surfaces

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.
