The identification of the first mobile colistin resistance (MCR) gene, mcr-1, in 2015 triggered
a rash of mcr screening reports. Subsequently, nine MCR-family genes and their variants …

Multiresistant Escherichia coli has been disseminated worldwide, and it is one of the major
causative agents of nosocomial infections. E. coli has a remarkable and complex genomic …

Mobile colistin resistance (mcr) genes (mcr-1 to mcr-10) are plasmid-encoded genes that
threaten the clinical utility of colistin (COL), one of the highest-priority critically important …

Multidrug-resistant (MDR) Escherichia coli strains have rapidly increased worldwide, and
effective antibiotic therapeutic options are becoming more restricted. As a polymyxin …

The worldwide spread of carbapenem-and polymyxin-resistant Enterobacterales represents
