Tóm tắt
Colistin is a last-resort antibiotic that is used to treat severe infections caused by MDR and extensively drug-resistant (XDR) bacteria. The World Health Organization (WHO) has designated colistin as a “highest priority critically important antimicrobial for human medicine” (WHO,
Critically Important Antimicrobials for Human Medicine
,
5th revision

), as it is often one of the only therapies available for treating serious bacterial infections in critically ill patients. Plasmid-borne
mcr
genes that confer resistance to colistin pose a threat to public health at an international scale, as they can be transmitted via horizontal gene transfer and have the potential to spread globally. Therefore, the establishment of a complete reference of
mcr
genes that can be used to screen for plasmid-mediated colistin resistance is essential for developing effective control strategies.
