Clostridium botulinum

Clos·trid·i·um bot·u·li·'num

a bacterial species that occurs widely in nature and is a frequent cause of food poisoning (botulism) from preserved meats, fruits, or vegetables that have not been properly sterilized before canning. The main types, A-F, are characterized by antigenically distinct, but pharmacologically similar, very potent neurotoxins, each of which can be neutralized only by the specific antitoxin; group C toxin contains at least two components; the recorded cases of human botulism have been due mainly to types A, B, E, and F; infant botulism occurs when colonization of the gastrointestinal tract with Clostridium botulinum results in absorption of the toxin through the gastrointestinal wall; type Cα causes botulism in domestic and wild water fowl; Cβ and D are associated with intoxications in cattle. Type E is usually associated with improperly processed fish products.

Clostridium botulinum

Microbiology A gram-positive, spore-forming anaerobe which produces a potent neurotoxin. See Botulism.

Botulism is a serious, paralytic illness caused by the action of neurotoxins, usually produced by Clostridium botulinum. These toxins block the release of the neurotransmitter acetylcholine at the neuromuscular junction, preventing muscle contraction and resulting in a characteristic floppy paralysis.
