CHROMOGENIC BACILLUS AGAR 

Majority of Bacillus species apparently have little or no pathogenic potential and are rarely associated with disease in humans or lower animals. The principal exception to this are Bacillus anthracis, the agent of anthrax, and Bacillus cereus , but a number of other species, particularly those of the B.subtilis group, have been implicated in food poisoning and other human and animal infections. Bacillus cereus causes food poisoning due to consumption of contaminated rice, other starchy foods such as potato, pasta and cheese have also been implicated, eye infections and a wide range of other clinical conditions like abscess formation, meningitis, septicemia and wound infection. Chromogenic Bacillus Agar is based on the formulation of MYP Agar formulated by Mossel et al and is used for enumeration of Bacillus cereus and Bacillus thuringiensis when present in large number in certain foodstuffs.
