What disease do possums give 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..

Can a horse fully recover from EPM?

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 horses get EPM from hay?

A: The main protozoan that causes EPM, Sarcocystis neurona, is found in the scat of some opossums. The horse eats feed (hay or grain/concentrates) that is contaminated with S. neurona from opossum feces, and the protozoa gains entrance into the horse’s blood through the intestinal tract.
