Sarcocystis Species

Infection with the coccidium Sarcocystis hominis, formerly known as Isospora hominis, is uncommon. Sarcocystis parasites are similar to I. belli in their biology,[51] but their life cycle requires the alternating infection of intermediate hosts, such as cattle and pigs, and definitive hosts, such as humans.

Specific therapy is ineffective and unnecessary, as the intracellular bradyzoites of Sarcocystis spp. are incapable of infecting new human cells and, therefore, there is no risk of recrudescence. Corticosteroids can be useful in the treatment of a hypersensitivity reaction following cyst rupture.
