The American Association of Equine Practitioners (AAEP) has published comprehensive guidelines to assist practitioners with identification, diagnosis, and control of equine protozoal myeloencephalitis (EPM), a progressively debilitating disease of the central nervous system that affects horses that reside or have spent time in North or South America.

“EPM is widely considered the most important infectious neurologic disease of horses in North America,” said guidelines author Amy Johnson, DVM, Dipl. ACVIM. “The variable clinical signs and widespread seroprevalence pose challenges to diagnosis. These guidelines aim to summarize essential information regarding this disease process, as well as highlight the three criteria for highest diagnostic accuracy in potentially affected horses.”

The EPM Guidelines, available as a PDF file, were reviewed and approved by the AAEP’s infectious disease committee and board of directors. View the guidelines or save them to your mobile device for future reference.

Besides EPM, AAEP guidelines for 20 other equine infectious diseases found in North American are available online, as well foreign animal disease guidelines for African horse sickness and glanders.
