Cell Structure, Metabolism and Life Cycle

Interesting features of cell structure; how it gains energy; what important molecules it produces.

Physiology and Pathogenesis

The pathogenicity of B. cereus, whether intestinal or non-intestinal, is intimately associated with the production of tissue-destructive exoenzymes.Among these secreted toxins are four hemolysins, three distinct phospholipases, an emesis-inducing toxin, and proteases. (1)

B. Cereus has been known to cause food-borne illness as well as skin infections in humans.
