Neospora hughesi

Species of bacterium

Neospora hughesi is an obligate protozoan apicomplexan parasite that causes myelitis and equine protozoal myeloencephalitis (EPM) in horses, and has only been documented in North America. EPM is a neurological disease from lesions in the spinal cord, brain stem, or brain from parasites such as N. hughesi or Sarcocystis neurona. Signs that a horse may have EPM include ataxia, muscle atrophy, difficulty swallowing, and head tilt. There are antiprotozoal drugs, such as the 28-day course of ponazuril, to treat the disease, as well as anti-inflammatories to alleviate neurologic symptoms
