Vancomycin-resistant enterococci were first recognized in Europe and the United States in the late 1980s. Since then they are now being recovered with increasing frequency3. Various phenotypes responsible for acquired resistance in enterococci have been described with high to low vancomycin resistance and cross-resistance to teicoplanin4. Detection has been difficult due to failure of commonly used susceptibility methods to identify those isolates with low-level resistance5.
An Agar screen test with BHI Agar supplemented with 6µg/ml of vancomycin has been recommended by the Clinical and Laboratory Standards Institute (CLSI) as a reliable method for the detection of all phenotypes of vancomycin-resistant enterococci1,2.
