One known Sarcocystis species and two found for the first time in red deer and wapiti (Cervus elaphus) in Europe.

Three species of sarcocysts from indigenous red deer and captive wapiti (Cervus elaphus, Cervidae) were characterized by means of light and electron microscopy. Two of them were found in this intermediate host species for the first time. Comparison of the literature and our results led to the conclusion that the three Sarcocystis species (Sporozoa, Sarcocystidae) should be provisionally designated as S. cf. grueneri, S. cf. capreolicanis and S. cf. hofmanni.
