Abstract: Six weaned puppies 4-weeks-old were fed once a composite of raw cameline meat (oesophagus, diaphragm, heart and skeletal muscles ) collected from camels slaughtered at El Gedarif city-Eastern Sudan. The puppies started to shed two types of Sarcocystis sporocysts 9-13 days after feeding raw meat. One type identified morphologically as Sarcocystis cameli, measured 13.2-13.6x6.5-9.5 �m with a patent period of 55-57 days. The second type had a larger size than the first one (vis Sarcocystis camelocanis), measured 16.0x9.9-11.5 �m and a shorter patent period (37-45 days). The two species which harvested from intestinal mucosae of the infected puppies were orally given to three naïve weand calf-camels (1x104 Sarcocystis sporocysts for each calf). The calves were medicated with amprolium at 100 gm kg-1 body weight to reduce the acute effects of Sarcocystis. Histological findings revealed the presence of two types of Sarcocystis tissue cysts ; one form had a thin cyst wall (0.5-1 �m in width), measured 72.5-264x9.9-29.5 �m, the ground substance extended inwards into the cyst in the form of narrow septae which divided the whole cyst into copartments. The other cyst measured 73-155x23-29.5 �m, had a thick cyst wall ( 2-3 �m in width ) which divided the cyst into compartments.
