What is the common term used for tetanus in equines?

The common term used for tetanus in equines is "lockjaw." This term refers to the characteristic stiffness and spasms of the jaw muscles that can occur during an episode of tetanus. Tetanus is caused by the bacterium Clostridium tetani, which produces a toxin affecting the nervous system and leading to severe muscle contractions and rigidity.

In horses, an infection can cause significant muscle stiffness and spasms throughout the body, but the term "lockjaw" specifically highlights the affected ability of the horse to open its mouth due to the tight contraction of the jaw muscles. This condition is critical to recognize, as it can indicate a serious health issue requiring prompt veterinary intervention. Understanding this terminology is essential for anyone studying equine health, as it helps in identifying and communicating about the disease effectively.
