What is the treatment for EPM?
Three FDA-approved anti-protozoal drugs are now available to treat EPM: Ponazuril (tradename Marquis; generic name toltrazuril sulfone), an oral paste administered once daily for 28 days. Pyrimethamine and sulfadiazine (tradename Rebalance), an oral suspension administered once daily for as long as 120 days.

Regarding this, can EPM be cured?
“That's because EPM is a progressive disease, although the progression can be halted and the horse can be cured. Protozoan parasites infect the inside of the nerve cells, and can actually kill the nerve cells as the parasite bursts open the cell and infects other cells.”
Furthermore, can a horse die from EPM? Without treatment, the progression of EPM is somewhat unpredictable, as the neurologic signs in untreated horses usually get worse—from the more mild signs to ataxia, recumbency or death in hours to years, with periods of severe exacerbations possible after prolonged periods of quiescence.
Subsequently, question is, what does EPM do to horses?
Equine Protozoal Myeloencephalitis (EPM) is a neurologic disease in horses caused by infection with the protozoan Sarcocystis neurona (SN). SN infects horses when they ingest the organism in contaminated feed or water. The definitive host of this organism is the opossum, which passes the organism in its feces.
How is EPM diagnosed?
Testing for EPM in horses: Testing both the cerebrospinal fluid (CSF) along with a blood serum sample is best. However, spinal taps can be risky and expensive so in many cases a positive serum IgG test combined with neurological signs and a history consistent with exposure to EPM will serve as a positive diagnosis.
Related Question AnswersCan you vaccinate for EPM?
“Because there is no cure for EPM, disease prevention plays a prominent role in protecting horses,” said Laura Petroski, B.V.M.S., a veterinarian for Kentucky Equine Research (KER). “To help protect horses against EPM caused by S. neurona, a vaccine was developed and conditionally licensed.Can humans get EPM?
Unlike Chagas, which affects humans and some other mammals, EPM only affects horses.How common is EPM?
The disease is widespread throughout North and South America. EPM is seen any time of year, with an estimated 50 percent of horses exposed to S. neurona, though less than 1 percent develop clinical EPM.How many horses die from EPM?
The original question was “How many horses die from EPM”? Retrospective analysis of our database indicated death in suspect EPM (seropositive for S. neurona) horses is 1.3% of cases. These horses have a history of multiple antiprotozoal treatments with diminishing returns.How is EPM spread?
Horses may develop EPM after ingesting feed or water contaminated with Sarcocystis neurona, a one-celled organism called a protozoan, that is spread by opossums and carried by other animals. Most horses who encounter the organisms that cause EPM put up an immune response that fights off the infection.Can you cure EPM in horses?
