EXPERIMENTAL INFECTION OF PONIES WITH SARCOCYSTIS FAYERI AND DIFFERENTIATION FROM SARCOCYSTIS NEURONA INFECTIONS IN HORSES [PDF]
Journal of Parasitology, 2004 Sarcocystis neurona and Sarcocystis fayeri infections are common in horses in the Americas. Their antemortem diagnosis is important because the former causes a neurological disorder in horses, whereas the latter is considered nonpathogenic. There is a concern that equine antibodies to S. fayeri might react with S.

Sarcocystis neurona-associated ataxia in horses in Brazil
Veterinary Parasitology, 1992 Sarcocystis neurona-like schizonts were found in sections of brain and spinal cord of two ataxic horses from Brazil. The diagnosis was supported by staining with anti-Sarcocystis serum in an immunohistochemical test. One of the affected horses was born in Argentina and raised in Brazil, and the other horse was born and raised in Brazil.

Sarcocystis neurona-Induced Myeloencephalitis Relapse Following Anticoccidial Treatment. [PDF]
The Journal of parasitology, 2019 Sarcocystis neurona is a ubiquitous parasite in the eastern United States, which is the principal causative agent in the neurologic disorder equine protozoal myeloencephalitis (EPM). While much is known about this protozoa's life cycle in its natural host, the opossum (Didelphis virginiana), little is known of how it acts in the aberrant equine host ...
