| R plasmids | Plasmid's carrying genes responsible for antibiotic (or antibacterial drug) resistance among bacteria (notably Enterobacteriaceae); they may be conjugative or nonconjugative plasmid's, the former possessing transfer genes (resistance transfer factor) lacking in the latter. Synonym: R factors, R plasmids, resistance factors, resistance-transferring episomes. (05 Mar 2000) |
