Mieloencefalite Protozoária Equina é considerada uma doença neurológia de importância onde o protozoário causador da doença é o Sarcocystis neurona e é transmitido aos equinos pela via oro-fecal por dejetos dos hospedeiros definitivos, os gambás (Didelphis virginiana e Didelphis albiventris). A doença causa quadro neurológico nos equinos devido à ação direta do parasita no tecido nervoso, causando resposta inflamatória secundária e sinais clínicos como atrofia muscular assimétrica, fraqueza muscular, incoordenação motora decorrente da diminuição da propriocepção. Os sinais da doença podem variar, pois vai depender da localização da lesão (cérebro, cerebelo ou ainda medula espinhal). Foram atendidos pelo Hospital Veterinário da Universidade de Mato Grosso, dois equinos portadores da doença. O tratamento de escolha foi realizado por meio de toltrazuril, sulfa/trimetoprim, anti-inflamatórios não esteroidais, tiocolchicosido e vitamina E e selênio. Contudo, a melhor forma de prevenção é evitar a contaminação do alimento pelo hospedeiro definitivo.

Sarcocystis neurona are parasitic protozoa responsible for the neurologic disease that can be fatal in wild and domestic animals, Equine Protozoal Myeloncephalitis (EPM). Recognized by its asymmetrical progressive and acute stages of ataxia of the limbs, loss of coordination, muscle atropy and declined response to sensory stimuli from the resulting spinal cord and brain damage. S. neurona is often the cause of EPM and similar signs in other animals that become infected by ingesting the sporocysts shed by the North America opossum (Didelphis virginiana) or related species. Unlike the other members of the apicomplexans, there is limited information about the composition of S. neurona antigens and life cycle. Developing diagnostic tools permit greater understanding of the exceptional disease. Collections of research data have cataloged information, to be summarized in this paper include the findings of tested sensitivity to S. neuron antibodies for serologic diagnostic assays; Enzyme-linked immunosorbent assays (ELISAs), Immunofluorescent staining Polymerase Chain Reactions (PCR), and Phylogenetic analysis. The research surrounding S. neurona include studies that analyze the pathology of this organism, to catalog the characteristics of this individual species, for the treatment of the disease and control of the pathogen. The purpose of this research paper is to inform readers about the nature of the disease-causing agent, Sarcocystis neurona.

Toxoplasma gondii, Neospora caninum and Sarcocystis neurona are related apicomplexan parasites that cause reproductive and neurological disorders in a wide range of domestic and wild animals. In the present study, the immunofluorescence antibody test (IFAT) was used to investigate the presence of antibodies against T. gondii, N. caninum and S. neurona in the sera of 11 free-living jaguars (Panthera onca) in two protected areas in the Pantanal region of Mato Grosso state, Brazil. Ten jaguars (90.9%) showed seropositivity for T. gondii, eight (72.7%) for S. neurona, and seven (63.6%) for N. caninum antigens. Our findings reveal exposure of jaguars to these related coccidian parasites and circulation of these pathogens in this wild ecosystem. To the best of our knowledge, this is the first serological detection of N. caninum and S. neurona in free-living jaguars.
