Tetanus antitoxin is prepared from the blood of healthy horses that have been specifically hyperimmunized. It is recommended for use when a non-immunized animal suffers a deep wound that may have been contaminated with soil, following castration or docking, and other situations where tetanus infection has been a problem.

Tetanus is caused by a neurotoxin (Poison) produced by growth of Clostridium tetani, an anaerobic microorganism, in necrotic tissue.
