Botulinum toxin, or botulinum neurotoxin (commonly called botox), is a neurotoxic protein produced by the bacterium Clostridium botulinum and related species.[24] It prevents the release of the neurotransmitter acetylcholine from axon endings at the neuromuscular junction, thus causing flaccid paralysis.[25] The toxin causes the disease botulism.[26] The toxin is also used commercially for medical and cosmetic purposes.[27][28] Botulinum toxin is an acetylcholine release inhibitor and a neuromuscular blocking agent.[1][23]

The seven main types of botulinum toxin are named types A to G (A, B, C1, C2, D, E, F and G).[27][29] New types are occasionally found.[30][31] Types A and B are capable of causing disease in humans, and are also used commercially and medically.[32][33][34] Types C–G are less common; types E and F can cause disease in humans, while the other types cause disease in other animals.[35]

Botulinum toxins are among the most potent toxins known to science.[36][37] Intoxication can occur naturally as a result of either wound or intestinal infection or by ingesting formed toxin in food. The estimated human median lethal dose of type A toxin is 1.3–2.1 ng/kg intravenously or intramuscularly, 10–13 ng/kg when inhaled, or 1000 ng/kg when taken by mouth.[38]
