This cross section of B. cereus (pronounced B. serious) shows a central dark endospore. Endospores in Bacillus species are produced when the organism slows down in stationary phase of growth. This microbe produces and enterotoxin which causes the intestine to secrete fluid into them. This can then lead to diarrhea. B. cereus grows on rice.
