Light micrograph of a colony of Bacillus cereus,a species of Gram-positive,aerobic,spore-forming bacteria. The Bacillus genus includes B. anthracis,the causative agent of anthrax. B. cereus is an important cause of food poisoning,occurring in soil & therefore on vegetables eaten by humans,notably rice. In recent times a special association with Chinese-style fried rice has been observed. Boiling rice does not destroy B. cereus,and if the rice is allowed to remain warm before being fried (at 30-37 degrees C.),the organism multiplies & secretes exotoxins that are not destroyed in the final frying.
