(Tıp) Toksini bağlayan ve onu nötralize eden cisimler, organizmaya özellikle parenteral yolla bir toksin kosulması sonucu kan selinde ve diğer hücre sıvılarında beliren ve doğmasına sebep olan spesifik toksini tadil edebilen antikor tipi, antitoksin
a medicine or substance produced by your body which stops the effects of a poison. Antibody formed in the body in reaction to a bacterial toxin, which it can neutralize. People who have recovered from bacterial diseases often develop specific antitoxins that give them immunity against recurrence. Injecting an animal (usually a horse) with increasing doses of toxin produces a high concentration of antitoxin in the blood. The resulting highly concentrated preparation of antitoxins is called an antiserum. The first antitoxin developed (1890) was specific to diphtheria; today, antitoxins are also used to treat botulism, dysentery, gas gangrene, and tetanus
A substance (sometimes the product of a specific micro-organism and sometimes naturally present in the blood or tissues of an animal), capable of producing immunity from certain diseases, or of counteracting the poisonous effects of pathogenic bacteria
