Abstract:

Sarcocysts found in the musculature of necropsied mammals were dried with hexamethyldisilazane and examined by scanning electron microscopy. The object of research in this morphological study was the outer surface configuration of the cysts wall. A smooth cysts wall without villar protrusions (Sarcocystis ef. sebeki European badger, Meles meles) was compared with 10 others each with its distinctly characterized villar protrusions. In scanning electron microcopy these resemble stumpy nails with angular heads (Sarcocystis sp. serow, Capricurnis crispus), tongues (S. sp. sambar, Cervus unicolor), ears (S. sp. wapiti, Cervus elaphus canadensis), elongated cones or clubs. (S. sp. domestic horse, Equus caballus), hairs (S. sp. Mongolian gazelle, Procapra gutturosa), and molar teeth (another S. sp. Mongolian gazelle). This study revealed that what appeared in light microscopy to be finger-like protrusions of Sarcocystis Hofmanni in roe dee (Capreolus capreolus), of Sarcocystis hominis in bison (Bison bison), of Sarcocystis hirsula in cattle (Boss taurus), and of Sarcocystis tenella in sheep (Ovis aries) were more similar to columns (S. hofmanni), straps (S. hominsi), stalked polyhedrons (S. Hirsuta), or cylinders (S. tenella).
