Characterization of class 1 integron associated with the formation of quadruple blaGES-5 cassettes from an IncP-1 β group plasmid in Pseudomonas aeruginosa
Nosocomial infections caused by carbapenems-resistant Pseudomonas aeruginosa are one of the most common challenges for antimicrobial therapy. Resistance to carbapenems in P. aeruginosa can be attributed to a multitude of intrinsic mechanisms, including various efflux pumps, the loss of OprD and elevated AmpC expression [1,2]. In addition to the intrinsic mechanisms, acquired mechanisms of resistance, such as the production of metallo-beta-lactamase (MBLs) and extended-spectrum beta-lactamases (ESBLs), have facilitated the emergence of carbapenems resistance, which has resulted in limited treatment options during recent decades [3].
