Multiplex Polymerase Chain Reaction Detection of vanA, vanB, vanC-1, and vanC-2/3 Genes in Enterococ

Resistance to the glycopeptide antibiotic vancomycin in enterococci, is phenotypically and genotypically heterogeneous. Three glycopeptide resistance phenotypes, VanA, VanB, and VanC, account for most glycopeptide resistance in enterococci; they can be distinguished on the basis of the level and inducibility of resistance to vancomycin and teicoplanin.
