Emergence of mcr-1 gene and carbapenemase-encoding genes among colistin-resistant Klebsiella pneumoniae clinical isolates in Jordan.

Background: Antimicrobial resistance (AMR) is a global threat that requires serious attention, particularly when it is developed against colistin, which is considered one of the 'last-resort' antibiotics for curing an infection. This study aimed to investigate the AMR profile of the Klebsiella (K.) pneumoniae clinical isolates and to obtain the comprehensive characteristics of the carbapenemases among the carbapenem-resistant K.
