Abstract Background: The emergence of antibiotic resistance, particularly plasmid-mediated colistin poses a critical threat to global public health, given colistin’s role as last-resort for treating multidrug-resistant (MDR) bacterial infections. Despite its significance, data on resistance and the prevalence mobile ( mcr ) genes in Nepal are scarce. This study aims investigate occurrence mobilized mcr-1 mcr-2 MDR Escherichia coli isolates from clinical specimens, highlighting burden...
