What is EPM?
EPM is a common neurological disease seen in horses throughout the United States. Distinct lesions in the central nervous system were first identified in the early 1960s by Dr. J. R. Rooney. In the early 1970s, Dr. J. P. Dubey identified a protozoal parasite associated with these lesions. The protozoa was ultimately determined to be a species of Sarcocystis and was named Sarcocystis neurona in the early 1990s.
