Morphologic and molecular identification of three macroscopic Sarcocystis species infecting domestic sheep (Ovis aries) and cattle (Bos taurus) in Egypt.

In a survey study on the macroscopic species of Sarcocystis infecting domestic sheep (Ovis aries) and cattle (Bos taurus) in Egypt, the macrosarcocysts of Sarcocystis gigantea and Sarcocystis medusiformis were detected in the carcasses of 33 domestic sheep out of a total of 250 (13.20%), whereas Sarcocystis hirsuta macrosarcocysts were found in 17 out of 150 cattle (11.33%) slaughtered at the municipal abattoirs of two different provinces in Egypt.
