Sarcocystosis
Sarcocystis spp.
Sarcosystis spp. - Hosts and distribution
Carnivore with herbivore or rodent IH
Sarcosystis spp. - Taxonomy
Subphylum: Apicomplexa
Sarcosystis spp. - Life cycle
Gametogony in small intestine of host
Oocysts sporulate in intestine and host sheds infective sporocysts
Schizogony occurs in herbivores or rodents (vascular endothelium)
Formation of bradyzoites in muscle
Host infected when they eat bradyzoites in tissue
Sarcocystis spp. - Pathology
Not in host
Seen in IH
