Clostridium botulinum

Species of endospore forming bacterium

Clostridium botulinum is a gram-positive, rod-shaped, anaerobic, spore-forming, motile bacterium that has the ability to produce botulinum toxin, which is a highly potent neurotoxin. C. botulinum is a diverse group of pathogenic bacteria. Initially, they were grouped together by their ability to produce botulinum toxin and are now known as four distinct groups, C. botulinum groups I–IV. Along with some strains of Clostridium butyricum and Clostridium baratii, these bacteria all produce the toxin.
