General description

Envirocheck Contact Enterobacteriaceae, a semi-quantitative detection of microorganisms on surfaces and in liquids, are flexible paddles that are coated with Tryptic soy agar to detect the bacteria belonging to the family Enterobacteriaceae from the samples. Slide A is coated with Plate Count Agar to obtain the total viable (aerobic) count. Slide B is coated with Violet Red Bile Dextrose (VRBD) Agar, recommended for the isolation and enumeration of all Enterobacteriaceae species in foodstuffs.

Application

This medium is recommended for the selective isolation and enumeration of all Enterobacteriaceae species in foodstuffs. Envirocheck contact slides can be used for both surface and liquid testing in industrial and environmental monitoring.

Analysis Note

Count the number of colonies on both sides of the paddle. Plate Count Agar: Count the number of colonies for obtaining the total aerobic bacterial count (TVC). Violet Red Bile Dextrose (VRBD) Agar: Degradation of dextrose is accompanied by production of acid which is indicated by a colour change to red and by zones of precipitated bile acids surrounding the colonies.
