An outbreak of extended-spectrum β-lactamase–producing Enterobacter cloacae (ESBL-ECL) occurred in our intensive care unit (ICU) and involved 18 patients (8 infected and 10 colonized). The mean age of patients was 69 years, and all infected patients had underlying medical conditions. Within hours' recognition of the spread of ESBL-ECL, the infection control team requested for staff education, reinforcement of infection control measures, and environmental screening. New transmissions were observed in the institution after weeks of enhanced infection control measures. Microbial swabbing revealed bacterial contamination of some mattresses and syphons with epidemiologic links between environmental, screening, and clinical isolates. This outbreak resulted in the temporary closure of the ICU for complete biocleaning.
