Clostridium botulinum is an obligatory anaerobic rod bacterium that posesses peritrichous flagella and can form spores.
Special significance has the toxin that is produces:
18-36 hours after ingestion different poisoning symptoms appear, that together, are called botulism. They mostly affect the musculature and autonomous nervous system.
The A and B subtypes of the toxin are used in injections to treat different neuromuscular disorders, for example blepharospasm, oromandibular dystonia and Torticollis spasticus.
Another indication is hyperhidrosis.
The most widely know use is the injection into the facial skin to paralyse the facial muscles and prevent wrinkles.
