Equine Protozoal Myelitis (EPM)

Unfortunately, I have heard of a case of this in the lot and Garrone, I have only heard of it before because my massage tutor an American has worked/ rehabilitated on horses with it and she has seen quite a few cases in the USA.

EPM is a complex disease, inflammation of the central nervous system and even more complex neurological symptoms.

It is caused by invasion and damage of the brain and or spinal cord by a Protozoal orgainism, Sacocysitis neurona. It is not spead from horse to horse, but by faeceal contamination of food and water by birds and of a rat type creature.
The symptoms can vary depending on the location of protozoal in the central nervous system and which nerves they affect. Symptoms may include lameness, muscle atrophy, loss of balance, stiffness, seizures and choking.
Blood and cerebrospinal fluid test are the only diagnosis.
Rapid diagnosis and aggressive drug treatment for several months are the only hope for recovery, young and old horses rarely make it.

The case I heard of was a extremely well breed foal, he was under 6 months. The owners decided to call it a day after 6 weeks of treatment as the foal had too many side affects of the aggressive treatment, a rectal prolapse being just one, they felt it wasn't fair to continue.
