the parasites of genus sarcocystis are among the most commonly found parasites in domestic ruminants and some species of sarcocystis can generate important economic loss when causing clinical and subclinical diseases. sarcocystis hominis, one of the three species of sarcocystis that cause muscular cysts in cattle, can infect the human intestinal tract. there is high infection rate of sarcocyst ...

Abstract Background Cattle are intermediate hosts of six Sarcocystis species, among which hominis and heydorni can infect humans through the consumption raw or undercooked meat. In addition to zoonotic potential, there is increasing interest in these protozoa because evidence supporting role spp. occurrence bovine eosinophilic myositis (BEM), a specific inflammatory myopathy leads carcass conde...

Sheep (Ovis aries) are intermediate hosts for at least six named species of Sarcocystis: S. tenella, S. arieticanis, S. gigantea, S. medusiformis, S. mihoensis, and S. microps. Here, only two species, S. tenella and S. arieticanis, were found in 79 of 86 sheep (91.9%) in Kunming, China, based on their morphological characteristics. Four genetic markers, i.e., 18S rRNA gene, 28S rRNA gene, mitoc...

Prevalence of species of Sarcocystis in muscle of 36 caribou, Rangifer tarandus terraenorae, shot in Newfoundland, Canada, was 53%. A greater percentage of infected animals were obtained from the central part of the island. The highest concentration of microscopic sarcocysts, 1/mm2 of tissue, was observed in a 5-year old animal. Although widely distributed throughout the body, cysts were more p...

Sarcocystis sporocysts from the intestines of 2 opossums (Didelphis albiventris) from Argentina were fed to gamma-interferon knockout (KO) and nude mice. Protozoal schizonts were seen in brain, liver, spleen, and adrenal glands of mice examined 33-64 days after feeding sporocysts. Sarcocysts were seen in skeletal muscles of KO mice 34-71 days after feeding sporocysts. Schizonts and sarcocysts w...

Abstract Apicomplexan parasites are responsible for important livestock diseases that affect the production of much needed protein resources, and those transmissible to humans pose a public health risk. Vaccines, recognized as cost-effective environmentally friendly method prevention infectious in livestock, can avert losses food decrease exposure zoonotic pathogens. This review focuses on need...

The current study was conducted in Misan Governorate to detect the parasite Sarcocystis spp. by both conventional and molecular methods identify species of this genus goats as intermediate hosts for multiple parasite. Regarding traditional study, rates infection with macroscopic type were low recorded 2% esophageal samples only goats. sizes cysts ranged between 1-10 mm length 2-6 width. Infecti...
