Kang Y.B.
For the comparison of surface fine structures in the proliferative forms of two major protozoan parasites, Toxoplasma gondii and Sarcocystis species in mammalian hosts, isolated from the artificially infected mice and from the naturally infected cattle, respectively, an SEM(Hitachi S-570) was applied to the fixed, dried and coated with gold ion on the microslide glasses. The tachyzoites of T. gondii from the peritoneal cavity of the mouse showed the crescent-like feature and measured as 5.57 micro m in length and 2.33 micro m in width, while the bradyzoites of Sarcocystis species from the heart muscle of slaughtered cattle was banana-shaped and measured 14.18 micro m in length and 2.85 micro m in width. On the surface of Sarcocystis species bradyzoite, a distinct elliptical micropore was identified in the high magnification observation of 60,000X, and it measured as 0.35 micro m in length and 0.18 micro m in width.
