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.
肠杆菌科细菌产extended-spectrum β-lactamase（ESBL-ECL）爆发发生在我们的重症监护病房（ICU），涉及 18 名患者（8 名感染，10 名定植）。患者的平均年龄为 69 岁，所有感染患者均有基础疾病。在发现 ESBL-ECL 传播的几个小时内，感染控制团队要求进行员工教育、加强感染控制措施和环境筛查。在强化感染控制措施数周后，该机构出现了新的传播。微生物拭子检测显示一些床垫和虹吸管存在细菌污染，且环境、筛查和临床分离株之间存在流行病学联系。此次爆发导致 ICU 暂时关闭，进行全面的生物清洁。
