Description

General description

ReadyPlate^™ CT VRBG Agar contact plates provide a ready-to-use method for environmental monitoring of surfaces in critical clean rooms and isolators.
Crystal violet and bile salts in the medium inhibit the accompanying bacterial flora. Degradation of glucose is accompanied by production of acid, which is indicated by a color change to red and by zones of precipitated bile acids surrounding the colonies. All Enterobacteriaceae are detected as they all degrade glucose to acid. The culture medium is not, however, specific for these organisms as some other accompanying bacteria (e.g. Aeromonas) also show these reactions.

Application

ReadyPlate^™ CT VRBG Agar contact plates are suitable for the selective isolation of Enterobacteriaceae or bile tolerant Gram-negative bacteria from non-sterile pharmaceutical products, foodstuffs, and other sample material.
