Genetic characterization of Vga ABC proteins conferring reduced susceptibility to pleuromutilins in Staphylococcus aureus

Antimicrob Agents Chemother. 2008 Dec;52(12):4507-9. doi: 10.1128/AAC.00915-08. Epub 2008 Oct 6.

Abstract

Retapamulin MICs of > or =2 microg/ml were noted for 6 of 5,676 S. aureus recent clinical isolates evaluated. The ABC proteins VgaAv and VgaA were found to be responsible for the reduced susceptibility to pleuromutilins exhibited by these six isolates.
