Clostridium botulinum . Clostridium botulinum is a Gram-positive, rod-shaped bacterium that produces several toxins. The best known are its neurotoxins, subdivided in types A-G, that cause the flaccid muscular paralysis seen in botulism. They are also the main paralytic agent in botox. C. botulinum is an anaerobic spore-former, which produces oval, . Botox® is made from Botulinum Toxin Type A, a protein produced by bacterium Clostridium. For the purposes of improving the appearance of wrinkles, small doses of the toxin are injected into the affected muscles blocking the release of a chemical that would otherwise signal the muscle to contract. The toxin thus paralyzes or weakens the injected muscle. The treatment usually begins to work within 24 to 48 hours and can last up to 4 months. The Food and Drug Administration (FDA) approved the cosmetic use of Botulinum Toxin Type A for the temporary relief of moderate to severe frown lines between the brow and recommends that the procedure be preformed no more frequently than once every 3 months. . and Fires.
