Sarcocystis neurona is the most important cause of a neurologic disease of horses, equine protozoal myeloencephalitis (EPM). Cats and other carnivores can act as its intermediate hosts and horses are aberrant hosts. Little is known of the sero-epidemiology of S. neurona infections in cats. In the present study, antibodies to S. neurona were evaluated by the S. neurona agglutination test (SAT). ...

Sarcocystis neurona is an important cause of equine protozoal myeloencephalitis (EPM) in horses in the Americas. An EPM-like neurological disease also has been reported from other mammals but it is difficult to induce this disease in the laboratory. A 4-month-old male domestic cat developed neurological signs 3 days following castration. The cat was euthanized 12 days later because of paralysis...

Sheep is the intermediate host of the protozoan parasite Sarcocystis tenella, while the dog is its definitive host. This study was conducted to determine the prevalence of natural infection with S. tenella in slaughtered Korean native goat, Capra hircus coreanae, in the Republic of Korea. H-E stained heart tissues were investigated for the presence of sarcocysts. Of the 103 goats, three (2.91%)...

Diclazuril is a benzeneacetonitril anticoccidial that has excellent activity against the extraintestinal stages of Toxoplasma gondii and Neospora caninum. It also is highly active against intestinal coccidia of poultry. The present study examined the efficacy of diclazuril in inhibiting merozoite production of Sarcocystis neurona and Sarcocystis falcatula in bovine turbinate cell cultures. Dicl...

Sarcocystis infection was detected in 93% of horses in Mongolia. Using the compress method, sarcocysts were found in the muscles of the diaphragm, heart and tongue in 40 of the 43 horses that were slaughtered at the Makh Impex Meat Company in Ulaan Baatar in July 1998. The muscle of the tongue showed the highest rate (97.5%) of infection. The distribution of sarcocysts in the muscles was positi...

Sarcocystosis, in recent times has been recognized as a disease in animals and man. With the attention of scientists on this problem all over the world, work on prevalence, morphology, life cycle, transmission, pathogenesis, immunology, biochemistry and prophylaxis of this parasite has been initiated in domestic animals in India.

There is currently no information regarding Sarcocystis neurona and Neospora hughesi infections in donkeys in Mexico. Here, we determined the presence of antibodies against S. neurona and N. hughesi in donkeys in the northern Mexican state of Durango. Serum samples of 239 domestic donkeys (Equus asinus) were assayed for S. neurona and N. hughesi antibodies using home-made enzyme-linked immunoas...
