Diphtheria antitoxin is a treatment used to neutralize the toxin produced by the bacterium Corynebacterium diphtheriae. This toxin can cause severe damage to tissues and organs, leading to serious complications, especially in children. The antitoxin is derived from the serum of horses immunized against the diphtheria toxin and is administered to patients diagnosed with diphtheria to prevent the progression of the disease.
