MexEF-OprN with MexS mutations conferring resistance to chloramphenicol, ciprofloxacin, and trimethoprim

Accession ARO:3004068
DefinitionThe MexEF–OprN efflux pump with MexS mutations conferring resistance to chloramphenicol and ciprofloxacin. The model includes the MexT regulator, as MexS is suggested to inactivate MexT.
AMR Gene Familyresistance-nodulation-cell division (RND) antibiotic efflux pump
Drug Classphenicol antibiotic, diaminopyrimidine antibiotic, fluoroquinolone antibiotic
Resistance Mechanismantibiotic efflux

Resistomes

Prevalence of MexEF-OprN with MexS mutations conferring resistance to chloramphenicol, ciprofloxacin, and trimethoprim among the sequenced genomes, plasmids, and whole-genome shotgun assemblies available at NCBI for 82 important pathogens (see methodological details and complete list of analyzed pathogens). Values reflect percentage of genomes, plasmids, or whole-genome shotgun assemblies that have at least one hit to the AMR detection model. Default view includes percentages calculated based on Perfect plus Strict RGI hits. Select the checkbox to view percentages based on only Perfect matches to AMR reference sequences curated in CARD (note: this excludes resistance via mutation as references in protein variant models are often wild-type, sensitive sequences).
