The aim of our study was the determination of prevalence of the sarcosporidiosis in the bovine carcasses in the slaughterhouses of El Harrach and the identification of involved species of Sarcocystis. Samples of oesophagi and diaphragms of 200 cattles brought down in the slaughterhouse of El Harrach were analyzed by the histo-pathological technique and the technique of digestion pepsique. We did not note macroscopic cyst in the carcasses inspection. The enzymatic digestion and the histo-pathological analysis revealed high rates of infestations (95%) and (80%) respectively. Cysts with thin wall of S. cruzi were dominant in diaphragms (94.2%) and in oesophagi (100%). A low rate of cysts with thick wall was detected in diaphragms (4.4%) and a rate of 0% in oesophagi. A single cyst of S. hominis was able to be diagnosed by photonique microscope in a diaphragm.
