Q: "How do you prevent a gelding from
getting Strangles a second time?" ~ Kriste K.
A: This is a great question.
Strangles is a very common respiratory disease of horses. Strangles is caused by the bacteria Streptococcus equi and is extremely contagious. Strangles can rapidly spread from one horse to another from nasal discharge and can easily be carried on hands, clothing or equipment. Horses with Strangles usually develop high fevers, swollen lymph nodes and nasal discharge. In severe cases lymph nodes in the back of the throat may swell so much that breathing may become labored (hence the name Strangles). After a horse has had Strangles they develop antibodies to the bacteria which protects them from getting the disease for several years. In most horses this protection last about five years, however the level and length of protection that horses develop varies from horse to horse. There are several steps that are crucial to preventing the spread of Strangles.
1.) Ideally isolate all new horses coming onto a property
for 3 weeks
2.) Isolate any horses with Strangles from the rest of the
herd. Even after symptoms resolve horses can continue to
shed and spread the bacteria for several weeks to months.
Therefore, it is important to confirm that they are no longer
shedding with laboratory tests prior to reintroducing them
to the herd.
3.) Disinfect!!!! Everything that comes in contact with a
Strangles horse is a potential source of infection to other
horses. This includes your hands, clothing, shoes, tack,
buckets, blankets.....you get the picture. When handling
horses with Strangles I always wear rubber gloves, disposable
plastic gowns and shoe covers. In addition, all equipment
that comes in contact with the horses from stethoscopes to
muck buckets gets disinfected. In Strangles outbreaks bleach
is your best friend.
There is also an available vaccination for Strangles but
unfortunately its effectiveness is questionable. Many
veterinarians including myself do not routinely recommend the
vaccination because it only protects horses for a very short
period of time and it has a higher incidence of side effects
than most vaccinations. For these reasons it is important to
speak with your veterinarian to determine if the Strangles
vaccination is appropriate for your horse. For the most in
depth information of Strangles, its symptoms, treatment,
prevention and possible complications associated with the
disease I recommend looking at the American College of Veterinary
Internal Medicine Consensus Statement on Strangles. This is a
composition of research and options compiled by experts in the
field with years of clinical and research experience.
