tox·in

(tŏk′sĭn)
A poisonous substance produced by a living organism. Toxins can be products of ordinary metabolism (such as lactic acid), can be produced to kill or immobilize prey (such as the toxins in snake venom), or can be produced for self-defense (such as the cyanide produced by several plants). Toxins produced by bacteria cause disease.
