Tetanus is caused by the bacterium Clostridium tetani, which produces a toxin affecting the nervous system. This disease can be particularly dangerous for sheep and goats, especially if they suffer wounds, such as cuts or abrasions, where the bacteria can enter the body. The anaerobic environment often found in deep wounds provides ideal conditions for the growth of these bacteria.

When an animal is wounded, the risk of tetanus infection increases, as the bacteria thrive in low-oxygen environments typical of some types of injuries. The symptoms of tetanus in goats and sheep include stiffness, muscle spasms, and, in severe cases, death if left untreated. Recognizing the symptoms early and providing the necessary veterinary treatment is crucial for affected animals.

In the context of other diseases listed, while they affect livestock, they are not primarily linked to wound infections in the same way that tetanus is. Foot rot is a bacterial infection affecting the hooves, pinkeye is an eye condition caused by bacteria or environmental factors, and listeriosis is associated with poor feed quality and can affect the nervous system and other organs rather than being directly related to wounds.
