AAEP Publishes Equine Protozoal Myeloencephalitis Guidelines

The American Association of Equine Practitioners (AAEP) has published on its website 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 once 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, DACVIM. “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.

Besides EPM, AAEP guidelines for 20 other equine infectious diseases are available at https://aaep.org/guidelines/infectious-disease-control/using-guidelines. In addition, two foreign animal disease guidelines—for African horse sickness and Glanders—can be found at https://aaep.org/infectious-disease-control/foreign-animal-disease-guidelines.
