About the baird parker + violet red bile glucose (vrbg) dipslides (box of 10)

This dipslide features two different agars (prepared culture medium). Baird Parker Agar is on one side and VRBG Agar is on the other side. Baird Parker Agar detects / grows Staphylococci and VRBG Agar detects / grows Enterobacteriaceae.

VRBG - Detects Enterobacteriaceae and is often used to test food samples as well as animal feed. Testing for total enterobacteriaceae as an indicator of hygiene levels is part of many food safety programs. Produces purple / pink colonies.

Baird Parker - This agar is selective for Staphylococci and is often used to test food samples.
