Phenotypic and genotypic characterization of clinical plasmid-mediated quinolone resistance (PMQR) and extended-spectrum beta-lactamase (ESBL)-producing Enterobacterales in two healthcare facilities in Douala, Cameroon

The emergence and escalation of antibiotic resistance in community and hospital settings remain a major public health concern worldwide. The co-occurrence of fluoroquinolone resistance in extended-spectrum β-lactamase-producing Enterobacterales (ESBL-E), which are responsible for life-threatening infectious diseases, poses a critical threat, leading to increase therapeutic costs, prolonged hospital stays, and higher mortality rates, particularly in low- and middle-income countries (LMICs) like C
