In this study, New Delhi metallo-beta-lactamase (NDM)-producing Enterobacteriaceae were identified in Irish recreational waters and sewage. Indistinguishable NDM-producing Escherichia coli by pulsed-field gel electrophoresis were isolated from sewage, a fresh water stream and a human source. NDM-producing Klebsiella pneumoniae isolated from sewage and seawater in the same area were closely related to each other and to a human isolate. This raises concerns regarding the potential for sewage discharges to contribute to the spread of carbapenemase-producing Enterobacteriaceae.
在本研究中，在爱尔兰的休闲水域和污水中鉴定出了产新德里金属β-内酰胺酶（NDM）的肠杆菌科细菌。通过脉冲场凝胶电泳鉴定出的难以区分的产NDM大肠杆菌，分别从污水、一条淡水溪流和一个人类源中分离得到。在同一区域从污水和海水中分离出的产NDM肺炎克雷伯菌彼此密切相关，且与一株人类分离株也密切相关。这引发了人们对污水排放可能导致产碳青霉烯酶肠杆菌科细菌传播的担忧。
