Characterization of antimicrobial resistance mechanisms in carbapenem-resistant <em>Pseudomonas aeruginosa</em> carrying IMP variants recovered from a Mexican Hospital

Abstract

This study shows the participation of different resistance mechanisms, which are reflected in the levels of MIC to carbapenems. This is the first report of the presence of three new variants of β-lactamases inside of new arrangements of class 1 integrons, as well as the presence of two plasmids carrying <i>bla</i> _IMP in the same <i>P. aeruginosa</i> strain isolated in a Mexican hospital.
