Restoration of vancomycin susceptibility in Enterococcus faecalis by antiresistance determinant gene transfer

Antimicrob Agents Chemother. 2001 Mar;45(3):973-5. doi: 10.1128/AAC.45.3.973-975.2001.

Abstract

We assessed the ability of gene transfer to reverse vancomycin resistance in class A (VanA) glycopeptide-resistant Enterococcus faecalis. Recombinant shuttle vectors containing a vanH promoter-vanA antisense gene cassette fully restored vancomycin susceptibility through a combined transcriptional activator binding domain decoy and inducible vanA antisense RNA effect.
