Genomic features of a carbapenem-resistant K. oxytoca strain

Introduction Antimicrobial resistance is a global issue associated with an increased and often unrestricted antibiotic use in clinical settings, which leads to the dissemination of carbapenem-resistant Enterobacterales (CRE) in healthcare facilities (World Health Organization, 2017).1 CRE constitutes a large group of bacteria with different mechanisms for drug resistance. Among them,…
