In the simplest terms, mcr-9 is a gene. It belongs to the mobilized colistin resistance (mcr) family. Like other members of this family (mcr-1 through mcr-8), its primary job is to protect bacteria from colistin.
Further studies are needed to elucidate the biochemical pathways involved in MCR-9-mediated colistin resistance and to explore potential synergies with other resistance mechanisms. In the simplest terms, mcr-9 is a gene
Furthermore, the presence of MCR-9 in CRE isolates highlights the need for enhanced infection control practices in healthcare settings. The spread of resistant bacteria within hospitals and communities can be prevented through strict adherence to hygiene protocols, improved antibiotic stewardship, and the implementation of robust surveillance systems. Further studies are needed to elucidate the biochemical
, one of the world's most critical "last-resort" antibiotics. First identified in 2019 by Cornell University researchers, it belongs to the mobile colistin resistance (MCR) family, which allows resistance to spread rapidly between different types of bacteria via jumping DNA molecules called Key Characteristics of MCR-9 , one of the world's most critical "last-resort" antibiotics
