Description Background: Colistin resistance among carbapenem-resistant Klebsiella pneumoniae (CRKp) strains at an accelerated rate poses a serious global threat which limits therapeutic options. Objective: In this study, 203 laboratory-archived uropathogenic K. pneumoniae isolates were screened for carbapenem and colistin resistance. Methods: Carbapenam resistance screening was performed using combined disc test. Colistin resistance was determined for CRKp isolates, according to clinical and laboratory standards institute- European Committee on Antimicrobial Susceptibility Testing guidelines. Polymerase Chain Reaction for carbapenamase genes (blaNDM-1, blaKPC-2 and blaOXA-1) and plasmid-mediated colistin resistance genes (mcr-1-2) were performed for the resistant isolates. Results: About 30% of the CRKp isolates were resistant to colistin; 57.1% and 35.7% of the isolates carried blaNDM-1 and blaOXA-1 gene, respectively. None of the isolates showed positive for blaKPC-2 and mcr (1-2) genes. Conclusion: Colistin resistance in the absence of a plasmid borne transfer mechanism was observed among our CRKp strains. Escalating colistin resistance is a crucial obstacle in treatment of K. pneumoniae infections and repurposing their usage is important to combat and control the resistance.
