|---|---|
| Clostridium haemolyticum | A species found in cattle dying of icterohemoglobinuria; it is pathogenic and toxic for guinea pigs and rabbits and produces an unstable, haemolytic toxin. (05 Mar 2000) |
| Clostridium histolyticum | A species found in war wounds, where it induces necrosis of tissue; it produces a cytolytic exotoxin that causes local necrosis and sloughing on injection; it is not toxic on feeding; it is pathogenic for small laboratory animals. (05 Mar 2000) |
| Clostridium histolyticum collagenase | <enzyme> An enzyme that catalyses the hydrolysis of collagen, preferentially at peptide bonds on the amino side of a glycylprolyl sequence. Synonym: clostridiopeptidase A, collagenase A, collagenase I. (05 Mar 2000) |
| Clostridium histolyticum proteinase B | A cysteine proteinase cleaving preferentially at the carboxyl side of arginyl and lysyl residues. It also has an esterase activity. Synonym: clostridiopeptidase B, Clostridium histolyticum proteinase B. (05 Mar 2000) |

| Clostridium novyi | A species consisting of three types, A, B, and C; type A, from a case of gaseous gangrene and from human necrotic hepatitis, produces gamma-toxin (a haemolytic lecithinase); B, from black disease (infectious necrotic hepatitis) of sheep, produces beta-toxin (a haemolytic lecithinase); and C, found in bacillary osteomyelitis of water buffaloes, does not produce toxin. Synonym: Clostridium oedematiens. (05 Mar 2000) |

Synonym: Clostridium oedematiens. (05 Mar 2000) |
| Clostridium parabotulinum | A species containing organisms formerly referred to as Clostridium botulinum types A and B; the types are identified by protection tests with known type antitoxin; it produces a powerful exotoxin and is pathogenic for man and other animals. (05 Mar 2000) |
| Clostridium paraputrificum | A species found in faeces, especially those of infants, gaseous gangrene, and postmortem fluid and tissue cultures; it is not pathogenic for rabbits or guinea pigs. (05 Mar 2000) |
| clostridium perfringens | The most common aetiologic agent of gas gangrene. It is differentiable into several distinct types based on the distribution of twelve different toxins. (12 Dec 1998) |
