New Websites Offer Latest Information on Equine Protozoal Myeloencephalitis and West Nile Virus

Protazil.com – EPM resource center

EPM is a progressive and potentially fatal infection of the central nervous system, which is caused by the single-celled protozoal microorganism,Sarcocystis neurona (S. neurona). Because the disease is progressive, early detection and veterinary intervention are critical to the horse’s chance of recovery. Protazil.com offers a centralized location for horse owners to research EPM and learn to recognize the early onset of the disease.

The website provides owners with:

• Up-to-date disease information and research through webinars, videos, fact sheets, educational brochures, etc.
• News and events surrounding EPM
• Management strategies to aid in prevention of EPM
• Treatment options to discuss with their veterinarian

The website also offers information on Merck Animal Health’s new EPM treatment product, PROTAZIL® (diclazuril) 1.56%. PROTAZIL is the only FDA-approved, alfalfa-based, pelleted EPM treatment product on the market.

“EPM can cause irreversible damage to the horse’s brain or spinal cord and is more likely to cause permanent damage if the disease is not detected early,” said Wendy Vaala, V.M.D., Dipl. ACVIM, senior equine technical services veterinarian for Merck Animal Health. “Although EPM only affects less than 1 percent of horses, it is critical that owners know what to do, just in case. Owners can increase their horse’s chance of a full recovery by talking to their veterinarian and educating themselves through websites like Protazil.com.”
