摘要：
Nosocomial infections caused by extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli are a major concern worldwide. There is an urgent need to identify bacterial factors promoting survival and persistence of these organisms in the nosocomial environment. Here, we describe the presence of a gene cluster, containing the Clp ATPase ClpK, within a collection of Danish ESBL-producing E. coli isolates. The cluster conferred thermoprotection upon the isolates, and thus might facilitate survival on medical devices exposed to semi-high temperatures in a hospital setting. (C) 2016 Institut Pasteur.
