INTENDED USE

BacterChrom^TM VRE Agar is a selective and differential chromogenic medium, containing 6 mg/L of vancomycin, intended for use in the qualitative direct detection of vanA/vanB transmissible VRE-type gastrointestinal colonization with vancomycin-resistant Enterococcus faecium and Enterococcus faecalis (VRE) to aid in the prevention and control of VRE in healthcare settings.
The medium can also be used as an early warning indicator for diagnostic tests of infections to signal the possible presence of multi drug-resistant bacteria.
BacterChrom^TMVRE Agar is not intended to diagnose VRE infection nor to guide nor monitor treatment for infections.
The packaging with semi-permeable Cellophane film helps balance the humidity of the environment during storage.

PRINCIPLES

BacterChrom^TM VRE Agar contains selective agents, including vancomycin, to inhibit the growth of vancomycin-susceptible organisms. Chromogenic substrates in the medium differentiate vancomycin-resistant Enterococcus species:
- Pink colonies: Presumptive vancomycin-resistant Enterococcus faecium or Enterococcus faecalis.
- No growth or other colors: Non-VRE organisms or susceptible strains.

BacterChrom^TM VRE Agar can be used with the following specimens: Rectal swab and stools.
Allow plates to reach room temperature before inoculation
Streak the specimen directly onto the agar surface for isolation
Incubate in aerobic conditions at 35 – 37 °C for 24 hours.

RESULTS

Microoragnism	Typical colony appearance
VRE. faecium; VRE. faecalis	pink to mauve
VRE. gallinarum; VRE. casseliflavus	blue or inhibited
Other Gram (+) bacteria	inhibited
Gram (-) bacteria	inhibited
Yeasts and mould	mostly inhibited

BacterLab ensures the quality of each product batch by testing with ATCC reference strains.
