What is the primary cause of tetanus?

Tetanus is an infection caused by a bacterium called Clostridium tetani. Spores of tetanus bacteria are everywhere in the environment, including soil, dust, and manure. The spores develop into bacteria when they enter the body. Unlike other vaccine-preventable diseases, tetanus is not spread from person to person.

Why is tetanus associated with horses?

Tetanus is caused by the anaerobic bacterium Clostridium tetani. The bacterium lives in the gut of horses and many other animals, and is passed in the manure so the organism is abundant and ubiquitous in soil. Spores of C. tetani can live in the environment for many years.

• Seizures.
• Horses with a tetanus infection become seriously ill very quickly and in many cases the disease is fatal despite all attempts at treatment.

Do horses need tetanus every year?

Tetanus is caused by production of endotoxins by the bacteria, Clostridium tetani. Vaccination is often given as a combination vaccine with equine influenza.
