RESUMO

We identified the genes encoding the AcrA-AcrB-TolC efflux pump in Enterobacter aerogenes and constructed acrAB and tolC mutants from a multidrug-resistant isolate. Both derivatives were more susceptible to antibiotics than the parental strain. Sequence analysis and complementation experiments revealed that the multidrug-resistant isolate is an acrR mutant.
