With all the recent focus on equine flu I thought I should add some information on tetanus.
Equine tetanus is considered much more important to vaccinate against and is a protection we would strongly advise all horses to have. Tetanus is frequently a fatal disease of horses that they do not catch from another horse, but get can get from contaminated wounds - including surgical wounds like castration, nail punctures of the hoof or tooth removal.
Here are some of the facts we know about equine tetanus:
- it is caused by a bacterium called Clostridium tetani which is found in the intestinal tract of horses and other animals
- the bacteria can survive for years in the environment in faeces and soil
- the bacteria multiplies rapidly and produces toxins which damage the horses nervous system (nerves damage)
- the majority of cases are fatal
- treatment (penecillin, tetanus antitoxin and supportive care) is expensive, intensive and horses are still often euthanased
Symptoms
- Protruding third eyelid (membrane at the inner corner of the eye)
- Extension and stiffness of the limb (a rocking horse stance)
- Spasm of jaw muscles (lock jaw) getting a common expression called sardonic smile
- Seizures
- These symptoms usually progress quickly and are often fatal
- A video showing a horse with milder symptoms of tetanus is below, more severe cases can be seen by searching youtube for equine tetanus.
Prevention
Tetanus is a preventable disease and causes fatalities every year.
Prevention is a simple one - vaccination! This has been shown to be safe and effective at preventing tetanus. We strongly recommend, along with welfare organisations including the RSPCA, that tetanus vaccines should be a minimum all horses should receive.
The course involves:
- For adult horses: a first vaccination followed by a second vaccine 4 to 6 weeks later, the first booster 12 months later, then a booster every 2 years to maintain immunity.
- For foals: the same but the first vaccine should be given at 4 to 6 months of age.
- For foals from unvaccinated mares: tetanus antitoxin - a product that can provide some immunity to infection - can be given at birth (there is a risk from infection via the umbilicus) and repeated if any injuries, followed by the same vaccination protocol as above.
- Remember all horses vaccinated for equine flu will also receive the tetanus vaccination every other year.
