Abstract: In the present study, the heteroxeneous life cycle of Sarcocystis sp. infecting camels were studied. A total of 180 slaughtered camels collected from different localities in Egypt were investigated for sarcocysts. Only 116 animals were found to be infected (the infection rate was 64%). Muscle samples of esophagus, diaphragm, tongue, skeletal, and heart muscles were examined. Exclusively, microscopic sarcocysts were detected in all examined organs. The infection rates of the esophagus, diaphragm, tongue, skeletal, and heart muscles were 60%, 50%, 40%, 40%, and 10%, respectively. By means of transmission electron microscopy, details of the ultrastructure of the sarcocysts were studied. The specific architecture and ornaments of the cyst wall, its protrusions, and the cyst interior were recorded. Unique features of protrusions of the primary cyst wall, the knob-like structures, arise around each protrusion. Experimental infection of carnivores by feeding heavily infected camel muscles revealed that the dog, Canis familiaris, is the only final host of the present Sarcocystis species. Gamogony, sporogonic stages, and characteristics of sporulated oocysts were also investigated.
