Sarcocystis hominis was first isolated from slaughtered cattle raised in Japan. Cysts were 1, 220-4, 460 × 80-384 γm in size and their wall was 3 to 6 γm thick and appeared radially striated in the histopathological sections because of the presence of palisade-like villar protrusions on the surface. The protrusions were 3.1-4.3 × 0.7-1.1 μm in size and had many microtubules in the core. Two cynomolgus monkeys, Macaca fascicularis, fed with the Sarcocystis cysts began to pass sporocysts, which measured a size of 14.3-15 × 9.5-10 γm, in the feces 10 days after ingestion.
