Prevalence and ultrastructure of Sarcocystis sp. from the red deer (Cervus elaphus L.) in Hungary Dr. Rolf ENTZEROTH — Dr. László NEMESÉRI — Dr. Erich SCHOLTYSECK Zoological Institute, University of Bonn, Federal Republic of Germany "Prevalence and ultrastructure of Sarcocystis sp. from the red deer (Cervus elaphus L. ) in Hungary" - Entzeroth, R. - Nemeséri, L. - Scholtyseck, E. Parasit. Hung. , 16: 47-52. 1983. ABSTRACT. Fifty specimens of Cervus elaphus from 4 geographical regions of Hungary were examined for Sarcocystis infections. The heart muscles of 15(30%) animals were found to be infected with Sarcocystis. The cysts were studied by means of electron microscopy. The discussion of the literature of Sarcocystis of Cervus elaphus led to the conclusion that the three species names, S. grüneri, S. cervicanis and S. wapiti are synonyms and that S. grüneri has priority. KEY WORDS: Sarcocystis grüneri, S. cervicanis, S. wapiti, red deer, Cervus elaphus, Hungary, heart muscle, electron microscopy, ultrastructure. INTRODUCTION Several reports of Sarcocystis infections of Cervus elaphus (Red Deer, Elk, Wapiti, Rothirsch, Maral) in Europe, Asia, North America and New Zealand have been published by YAKIMOFF and SOKOLOFF, 1934; KRYLOV and SAPOZHNIKOV, 1965; DROST and GRAUBMANN, 1975; KÁVAI and SUGÁR, 1976; DROST, 1977; MARGOLIN and JOLLEY, 1979; COLLINS and CHARLESTON, 1979; HIEPE et al., 1980; DUBEY, 1980; HERNANDEZ RODRIGUEZ et al., 1981a; LITVINOV, 1982; POLOMOSHNOV, 1982; SPEER and DUBEY, 1982. Three species names have been given so far for Sarcocystis in Cervus elaphus: Sarcocystis grüneri, YAKIMOFF and SOKOLOFF (1934) found this species in a Sibirian red deer (Cervus canadensis asiaticus Erxleb. = Cervus elaphus according to HONACKI, KINMAN and KOEPPL, 1982). The second species name, Sarcocystis cervicanis , was given for a Sarcocystis species of C. elaphus in Spain by HERNANDEZ RODRIGUEZ et al. (1981a). The third species name, Sar cocystis wapiti, was given by SPEER and DUBEY (1982). In the first case the morphology of the merozoite (cystozoite) in the cysts, in the second and third case cysts morphology and life cycle studies were the base of the description. The present report deals with the prevalence of Sarcocystis and the ultrastructure of the Sar cocystis cyst of infected heart muscle of C. elaphus in Hungary. MATERIAL AND METHODS Samples of esophagus and heart muscle were collected from recently shot red deer from 4 different geographical regions of Hungary. The tissue was fixed in 2. 5% glutaraldehyde in cacodylate buffer pH 7.4. Histological sections were made on a REICHERT-JUNG Frigocut
