An antitoxin is a type of antibody that neutralizes toxins produced by certain bacteria or other harmful organisms. It is often used in medical treatments to counteract the effects of these toxins, which can cause serious illness or even death. Antitoxins are typically derived from the blood of animals, such as horses, that have been immunized against specific toxins. In medicine, antitoxins are crucial for treating conditions like diphtheria and botulism. They work by binding to the toxins in the body, preventing them from causing further harm. This therapeutic approach helps to reduce symptoms and improve recovery outcomes for affected individuals.
