Clos·trid·i·um dif·fi·cileAvoid the mispronunciation dĭf-ĭ-sēl' of this Latin word, which is correctly pronounced dĭ-fĭs'ĭ-lē.
a bacterial species found in feces of humans and animals. It colonizes newborn infants, who are spared from toxin-induced diarrheal disease. Pathogenic for human beings, guinea pigs, and rabbits; frequent cause of colitis and diarrhea following antibiotic use. Found to be a cause of pseudomembranous colitis and associated with a number of intestinal diseases that are linked to antibiotic therapy; also the chief cause of nosocomial diarrhea.
Clostridium difficile(dĭf′ĭ-sēl′, dĭf′ĭ-sēl′, dĭf′ĭ-kē′lā)
A bacterium that causes an infectious form of severe diarrhea especially in elderly people on antibiotic therapy and in hospitalized patients. Also called C. diff..
A common inhabitant of the colon flora in human infants and sometimes in adults. It produces a toxin that causes pseudomembranous enterocolitis in persons receiving antibiotic therapy causing watery diarrhea. The species affects guinea pigs and rabbits as well as humans.
Clostridium difficileA common cause of bacterial colitis; it is the causative agent in 99% of pseudomembranous colitis, and 20-30% of antibiotic-associated diarrhea
Clos·trid·i·um dif·fi·ci·le(klos-trid'ē-ŭm di-fis'i-lē)
Gram-positive obligate anaerobic or microaerophilic, rod-shaped bacterium; causes sometimes severe antibiotic-associated colitis.

Clostridium difficileA fecal organism endemic in hospitals and responsible for the majority of hospital-acquired cases of diarrhoea in elderly patients. Its prevalence in hospital is largely due to the high levels of antibiotic usage. Bowel infection can be cleared by oral treatment with the antibiotic vancomycin which is not appreciably absorbed into the bloodstream. Up to 40 percent of hospitalized patients are colonized with this organism. Only about 3 percent of healthy adults carry it. A previously uncommon strain with variations in toxin genes has emerged as a cause of C. difficile -associated disease.
a genus of anaerobic spore-forming bacteria of the family Bacillaceae. Most are gram-positive rods.

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.
involved in the spoilage of meat.
may be associated with colitis X in horses.
formerly called C. feseri. See blackleg.
cause of ulcerative enteritis and liver necrosis in quail, turkeys, grouse, partridge and chickens. Not an accredited species.

now called C. chauvoei (above).
formerly called C. novyi type D. See bacillary hemoglobinuria.
a species found in feces, soil and sometimes wound infections. An important cause of meat spoilage.
a thermophilic spoiler of canned meat producing hydrogen sulfide gas and causing purple staining of the inside of the can. Now called Desulfotomaculum nigrificans.
see bacterial overgrowth.
a proteolytic subgroup of C. botulinum; not a valid species.
causes deep bone taint in hams. See also C. putrificum (below).
a cause of bone taint in cured hams. There is no detectable abnormality on the surface of the ham.
cause of a small proportion of cases of gas gangrene in ruminants. See also abomasitis.
associated with enteritis and enterocolitis in rabbits, guinea pigs and foals.
an apathogenic clostridium often found in lesions of gas gangrene.
a common inhabitant of soil and human and horse intestines, and the cause of tetanus in humans and domestic animals.
found in fight abscesses and pleurisy in cats.
