A multidrug resistance regulatory chromosomal locus is widespread among enteric bacteria.

The Journal of infectious diseases - 1 Aug 1993

Cohen S P, Yan W, Levy S B

Abstract excerpt

Constitutive expression of the mar operon (marRAB) in Escherichia coli produces a multiple antibiotic resistance phenotype mediated by the expression of multiple genetic loci in response to regulatory proteins in the operon. A mar-specific DNA probe was used to search for the operon in bacterial strains representing 53 species and 27 genera. Among these, 6 other Enterobacteriaceae, Salmonella, Shigella,...
