Characterization of the earliest known Staphylococcus aureus plasmid encoding a multidrug efflux system.
The staphylococcal qacB-encoding multidrug resistance plasmid pSK156, isolated from a clinical strain dating from 1951, was characterized. Comparison of the regions flanking qacB with other qacA- and qacB-encoding plasmids provided insights into the evolution and dissemination of these multidrug efflux genes and led to the detection of the earliest known copy of the insertion sequence IS257.
