Sarcocysts morphologically not distinguishable from Sarcocystis gracilis of roe deer (Capreolus capreolus, Cervidae) were found in the skeletal musculature of dwarf zebu and humpless cattle (Bos taurus, Bovidae). We contribute to the identification of this species by means of scanning electron microscopy. Special attention is paid to the species-specific cyst wall structure. Our findings confirm previous descriptions by light and transmission electron microscopy and support the peculiarity and uniqueness of the cyst wall type ‘gracilis’.
