Fatal Perinatal Sarcocystosis in a Lamb
The Journal of Parasitology, 1989A 3-wk-old lamb died because of neurological disease. The predominant microscopic lesions were in the brain and spinal cord and consisted of nonsuppurative encephalomyelitis with severe gliosis throughout the gray and white matter. Immature and mature schizonts, 15.7 x 10.6 microns (8-30 x 6-18 microns), occurred in capillaries and were structurally ...

Sarcocystosis in an aborted bovine fetus
Journal of the American Veterinary Medical Association, 1982SUMMARY Sarcocystosis was diagnosed in an aborted bovine fetus. Immature and mature schizonts of Sarcocystis were disseminated in the vascular endothelium of all organs, but especially the brain. Microscopic granulomas, focal gliosis, and petechial hemorrhages in the neuropil were scattered in the brain. Multifocal collections of mononuclear cells were

Livestock, 2014
Most Sarcocystis spp. infestations are asymptomatic and the cysts in various muscles are only discovered at slaughter. Sheep of all ages may be affected by sarcocysts but neurological signs originating from spinal cord disease are believed to be the most common disease presentation and are reported in 6 to 12-month-old lambs.

Encephalitic sarcocystosis in a newborn calf
American Journal of Veterinary Research, 1983SUMMARY Sporozoan schizonts were seen in histologic sections of cerebrum from a Hereford calf that died immediately after birth. Schizonts appeared in endothelial cells of small vessels in the gray and white matter. Rosette and palisade configurations of merozoites in schizonts, as well as the size of schizonts (15 to 40 × 21 µm) and merozoites (8 µm),

Clinical Muscular Sarcocystosis in a Dog
Journal of Parasitology, 2005Muscular sarcocystosis is a rare infection in dogs. Clinical myositis associated with an unidentified species of Sarcocystis was diagnosed in an adult dog from Canada. There was granulomatous myositis associated with numerous immature sarcocysts in a muscle biopsy obtained from the dog. The sarcocysts were up to 550 microm long and up to 45 microm wide.

Sarcocystosis (sarcosporidiosis)
2010Abstract Sarcocystosis is characterized by the invasion of various tissues by protozoa of the genus Sarcocystis. S. hominis (intermediate host domestic cattle) and S. suihominis (domestic pig) are the most significant to humans, to whom they are transmitted by ingestion of uncooked beef or pork.
