[Detection methods for drug-resistant bacteria in routine examination--VRE].
When testing vancomycin susceptibility against enterococci, plates should be held a full 24 hours then examined using transmitted light. The presence of a haze or any growth within the zone of inhibition indicates resistance. Perform vancomycin MIC and tests for motility and pigment production to distinguish species with acquired resistance(vanA and vanB) from those with intrinsic, intermediate-level resistance to vancomycin(vanC) such as E. gallinarum, E. casseliflavus or E. flavescens.
