How does the diphtheria antitoxin work?

Why horse is selected for preparation of diphtheria antitoxin?

Initially joined by a few sheep, goats and dogs, the horses prevailed because they were larger and better antitoxin factories: when systematically injected with diphtheria toxin, their immune systems were prompted to develop neutralizing antibodies against the germ’s poison.

Why is an antitoxin required to treat cases of diphtheria?

Antitoxin is most effective in the early stages of the infection because it neutralizes free diphtheria. A 14-day regimen of erythromycin or intramuscular procaine penicillin G also is recommended to treat active cases.

Why is anti diphtheria toxin administered?

Patients with diphtheria are treated with equine diphtheria antitoxin, which neutralizes unbound diphtheria toxin. This treatment can result in serum sickness, an immune complex disease, so a better treatment for diphtheria patients would be desirable.
