Botulinum toxin

Protein and neurotoxin produced by the bacterium Clostridium botulinum.

It is the most acutely lethal toxin known, with an estimated human median lethal dose (LD-50) of 1.3–2.1 ng/kg intravenously or intramuscularly and 10–13 ng/kg when inhaled.

Botulinum toxin (BTX) can cause botulism, a serious and life-threatening illness in humans and animals. Three forms of botulinum toxin type A (Botox, Dysport and Xeomin) and one form of botulinum toxin type B (MyoBloc) are available commercially for various cosmetic and medical procedures.
