Botulism is a rare but serious condition caused by toxins from bacteria called Clostridium botulinum.According to mayoclinic.org there are three common forms of botulism:. Found insideThese bacteria and their spores and ubiquitous, and the majority of them do not produce neurotoxins. The selective advantage of producing such potent toxin is still a matter of speculation (see Popoff, this volume). Botulinum neurotoxins are 150-kDa exo-toxins that are produced by Clostridium botulinum, C. butyricum and C. baratii. It produces spores that survive in improperly preserved or canned food, where they produce a toxin. Clostridium perfringens toxins cannot be spread from person to person and they do not grow or increase in number in the body. What does Clostridium botulinum look like?
