HardyCHROM™ VRE Agar is a selective and differential chromogenic medium, containing vancomycin, intended for use as a plating technique to obtain a pure culture of vancomycin-resistant Enterococcus faecium and Enterococcus faecalis (VRE).
The selective components in HardyCHROM™ VRE Agar are agents that inhibit the growth of yeast, gram-negative bacteria, non-Enterococcus gram-positive bacteria, and Enterococcus vancomycin-sensitive bacteria (e.g., vancomycin). The presence of chromogens allows the differentiation of VRE. The colonies of those bacteria that release products when they use the chromogens as a substrate source appear colored.
HardyCHROM™ VRE Agar is available in a monoplate for plating of laboratory samples (G333) and a contact plate for environmental monitoring (P19).
E. faecalis produces colonies that are dark red in color, and may have a golden sheen. E. faecium produces colonies that are dark blue in color.
See the Instructions for Use (IFU) below (under Technical Information) for the complete procedure with color photos.
Hardy Diagnostics was the first company to introduce chromogenic prepared media to the United States in 1996. You can expect Hardy Diagnostics to be the leading innovator in chromogenic plating methods.
This media is to be stored and incubated in the dark. If you have a light in your refrigerator, incubator, or you leave the media exposed to light on the bench top, Hardy Diagnostics offers free Blok-Boxes. Blok-Box is a reusable cardboard box that holds one sleeve of ten petri plates.
Please ask Customer Service if you would like a free Blok-Box sent with your order. Customer Service – (800) 266-2222.
