EPM can cause nerve damage, so a reader wonders if an affected horse can be rehabilitated. … For horses that do recover, the improvement is based on the initial severity of the clinical signs (see box). However, not all horses that “improve” according to the clinical scale are able to be safely ridden again.

What is the treatment for EPM in horses?

How is EPM treated? Treatment to control infection should include an FDA-approved anticoccidial drug (Ponazuril, Diclazuril, Sulfadiazine/Pyrimethamine). Additional treatments should be provided as needed based on the severity of the clinical signs and any associated complications.

How quickly does EPM progress?

Our results indicate that EPM can manifest as long as 90 days after the parasite has crossed the blood-brain barrier (data not shown), but in most of the challenged horses evidence of infection occurred within 30 days and ataxia was present by 60 days.

Can EPM come on suddenly?

“EPM can evolve slowly or present suddenly with varied signs from mild to severe,” Reuss says. There are several factors that can determine its progression and severity, including: How long the horse has been infected; The points in the brain or spinal cord where the sporocysts have infected; and.

Is there a test for EPM?

EPM is a neurological disease of the Americas. It is most commonly caused by the parasite Sarcocystis neurona and more rarely by Neospora hughesi. The standard of practice for diagnosis is to perform a complete neurological exam, accompanied by laboratory tests that detect an immunological response to infection.

Can you cure EPM?

Equine protozoal myeloencephalitis (EPM) is a parasitic infection of horses caused by Sarcocystis neurona that can result in devastating neurologic disease. Infection with S. neurona can also cause a neuromuscular disease that doesn’t result in destruction of neurological tissues, and this is treatable.

Can a human get EPM?
