Clostridium bifermen´tans  a species common in feces, sewage, and soil and associated with gas gangrene.

Clostridium botuli´num  the causative agent of botulism, divided into six types (A through F) which elaborate immunologically distinct toxins.

Clostridium diffi´cile  a species often occurring transiently in the gut of infants, but whose toxin causes pseudomembranous enterocolitis in those receiving prolonged antibiotic therapy.

Clos·trid·i·um (kl-strd-m)

n.

A genus of rod-shaped, spore-forming, chiefly anaerobic bacteria including the nitrogen-fixing bacteria found in soil and those causing botulism and tetanus.

Clostridium

A genus of deadly bacteria that are responsible for tetanus and other serious diseases, including botulism and gangrene from war wounds. Clostridia thrives without oxygen.

Mentioned in: Tetanus

Clostridium

[-ē·əm]

Etymology: Gk, kloster, spindle

a genus of spore-forming anaerobic bacteria of the Bacillaceae family: Clostridium novyi, C. septicum, and C. bifermentans are involved in gas gangrene; C. botulinum causes botulism and produces the toxin Botox used in some cosmetic procedures; C. perfringens causes food poisoning, cellulitis, and wound infections; C. tetani is the cause of tetanus.

closed reduction, for jaw fracture,

n a process by which the broken portions of the jaw are approximated and stabilized without surgically opening the mucosal covering. The fixation of the reestablished approximation of the parts is accomplished with preformed bars attached to the teeth with ligatures or elastic bands.

Clostridium bifermentans, Clostridium sordelli

see malignant edema.

Clostridium botulinum

causes botulism from neurotoxin produced during vegetative growth. C. botulinum types B, C and D are associated with disease in animals but the type prevalence varies geographically. See botulism.

Clostridium butyricum

involved in the spoilage of meat.

Clostridium cadaveris

may be associated with colitis X in horses.

Clostridium chauvoei

formerly called C. feseri. See blackleg.

Clostridium colinum

cause of ulcerative enteritis and liver necrosis in quail, turkeys, grouse, partridge and chickens. Not an accredited species.

Clostridium difficile

see antibiotic-associated colitis.

Clostridium feseri

now called C. chauvoei (above).

Clostridium haemolyticum

formerly called C. novyi type D. See bacillary hemoglobinuria.

Clostridium histolyticum

a species found in feces, soil and sometimes wound infections. An important cause of meat spoilage.

Clostridium nigrificans

a thermophilic spoiler of canned meat producing hydrogen sulfide gas and causing purple staining of the inside of the can. Now called Desulfotomaculum nigrificans.

Clostridium novyi

see infectious necrotic hepatitis. See also C. haemolyticum (above). Previously called C. oedematiens. Type A causes malignant edema in cattle and sheep, and big head in rams, type B causes infectious necrotic hepatitis (black disease), and type C has been associated with osteomyelitis in buffalo.

Clostridium overgrowth

see bacterial overgrowth.

Clostridium parabotulinum

a proteolytic subgroup of C. botulinum; not a valid species.

Clostridium perfringens

cause of enterotoxemia. Type A causes malignant edema, type B causes dysentery in lambs and enterotoxemia, type C causes struck in sheep and necrotic enteritis in piglets, type D causes enterotoxemia and type E causes necrotic enteritis. Previously called C. welchii.
