First Report of Extended-Spectrum β-Lactamase () and Colistin Resistance Gene in E. coli of Lineage ST648 from Cockroaches in Tunisia.

The emergence of multidrug-resistant bacteria has become a major problem. Cockroaches may play an important role in the spread of those bacteria between the environment and humans. This study was designed to screen extended-spectrum β-lactamase (ESBL)-producing and colistin-resistant strains and to investigate the molecular support of multidrug-resistant in the external surface and gut homogenates of cockroaches collected from different locations in Tunisia.
