is nearly identical with that reported by HERNANDEZ RODRIGUEZ et al. 1981b, SPEER and DUBEY, 1982 but also with one type of cysts reported from the roe deer C. capreolus (SCHRAMLOVA and BLAZEK, 1978; ENTZEROTH, 1982). This finding leads to the conclusion that Capreolus capreolus and Cervus elaphus may have one common species of Sarcocystis. Reports by ERBER(1980) and FAYER (1981) indicate that host specificity of Sarcocystis species for the intermediate host is not always so strict as assumed previously. This leaves the question open whether there are more Sarcocystis species that can be transmitted from wild to domestic animals, as indicated by FAYER (1981). The infection rate determined with the histological method in the present study was 30%. It was rather low, compared with data of the literature (DROST and GRAUBMANN (197 5), 84%; KÁVAI and SUGÁR (197 6), 78%; POLOMOSHNOV (1982), 53%; LITVINOV (1982), 90%; COLLINS and CHARLESTON (1979), 30%; HERNANDEZ RODRIGUEZ et al. (1981a), 76. 3-95. 6%. These results also depend, however, on the methods used (trichinoscope, histological or digesting method). The latter one is considered to be the most sensitive one but may also lead to errors, because merozoites of other cyst-forming Coccidia ( Cystoisospora, Toxoplasma, Hammondia) could be found in the digest which cannot be distinguished from the merozoites of Sarcocystis species. The predominant site of infection with Sarcocystis of Cervus elaphus in our study was the heart muscle. A similar finding was reported by NAVARRETE et al. (1978). DROST and GRAUBMANN (197 5), however, found that abdominal muscle was the most often parasitized. The ultrastructure of the cyst wall and cyst contents in the present study is typical for Sarcocystis species (see CHOBOTAR and SCHOLTYSECK, 1982). It remains unknown, however, what significance the globular structures inside the cysts, resembling degenerating merozoites, may have. They look different from degenerating Sarcocystis cysts infected by bacteria (MEHLHORN and SÉNAUD, 1975). és ultrastruktúrája A szerzők Magyarország 4 megyéjében 50 gímszarvasból gyűjtött izommintát vizsgáltak meg szövettanilag a Sarcosporidium-fertőzöttség kimutatására. 15 állat (30%) szívizomzatában Sarcosporidium-cystákat találtak. A cystákat elektronmikroszkópos vizsgálattal tanulmányozták. À szarvasok sarcosporidiosisára vonatkozó irodalmi adatokból arra következtetnek, hogy az eddig leírt 3 faj, a Sarcocystis grüneri , a Sarcocystis cervicanis és a Sarcocystis wapiti szinonimák és a S. grüneri prioritással rendelkezik.
