The vancomycin agar screen is used to detect vancomycin-resistant enterococcal colonies that have been isolated from clinical or surveillance cultures. A standard number of bacteria is inoculated onto BHI agar containing 6 µg of vancomycin per ml. Following incubation, the appearance of growth indicates that the enterococcal isolate is likely to be resistant to vancomycin. MIC and species identification tests are subsequently required to determine if the isolate is a true vancomycin-resistant enterococcus (VRE) ( 1 , 2 ).
