About the kaa & violet red bile glucose (vrbg) dipslide (box of 10)

This dipslide tests for enterococci on one side and enterobacteriaceae on the other side.

The KAA agar is selective for the isolation of enterococci in food. The VRBG agar detects enterobacteriaceae in food and environmental samples.

Enterococci will present as white or grey colonies with black areas surrounding them.

Enterobacteriaceae will present as pink / purple colonies.

Any colonies present indicate infection / contamination of some sort.

Industry sectors include

  • Food
  • Animal Feed
  • Environmental

Please note that dipslides should not come into contact with the body and that samples should be taken via swab or cup / tube before streaking on to the slide.
