How the Anaerobic Enteropathogen Tolerates Low O Tensions.

is a major cause of diarrhea associated with antibiotherapy. After germination of spores in the small intestine, vegetative cells are exposed to low oxygen (O) tensions. While considered strictly anaerobic, is able to grow in nonstrict anaerobic conditions (1 to 3% O) and tolerates brief air exposure indicating that this bacterium harbors an arsenal of proteins involved in O detoxification and/or protection.
