exotoxin[¦ek·sə¦täk·sən] (microbiology) A toxin that is excreted by a microorganism. exotoxin
exotoxin [ek´so-tok″sin] a potent toxin formed and excreted by the bacterial cell and found free in the surrounding medium; exotoxins are the most poisonous substances known. They are protein in nature and heat labile, and are detoxified with retention of antigenicity by treatment with formaldehyde. Bacteria of the genus Clostridium are the most frequent producers of exotoxins; diphtheria, botulism, and tetanus are all caused by such toxins. adj., adj ex´otoxic.ex·o·tox·in (ek'sō-tok'sin), A specific, soluble, antigenic, usually heat labile, injurious substance elaborated by certain gram-positive or gram-negative bacteria; it is formed within the cell, but is released into the environment where it is rapidly active in extremely small amounts; most exotoxins are proteinaceous (MW 70,000-900,000) and can have the toxic portion of the molecule destroyed by heat, prolonged storage, or chemicals; the nontoxic but antigenic form is a toxoid.
