The fine structure of Sarcocystis spp. from donkeys (Equus asinus) in Egypt is described. Sarcocysts were found in the oesophagus, diaphragm and heart of 18 of 20 donkeys. Only one type of mature muscle cyst was found. Sarcocysts were 120-410.6 X 48.4-50.2 microns. The primary cyst wall had numerous 3.3-3.7 microns villi. Each villus contained 20-60 fibrillar elements which extended from the ends and sides of the villi throughout the ground substance, where they became tightly packed. The bundles of fibrillar elements formed junctions with the pellicles of the metrocytes. Ultrastructurally, Sarcocystis spp. of the donkey was similar to sarcocysts previously described from the horse.
描述了来自埃及驴（Equus asinus）的肉孢子虫属（Sarcocystis spp.）的精细结构。在20头驴中的18头的食管、膈肌和心脏中发现了肉孢子囊。仅发现了一种类型的成熟肌囊。肉孢子囊大小为120 - 410.6×48.4 - 50.2微米。初级囊壁有许多3.3 - 3.7微米的绒毛。每个绒毛含有20 - 60个纤维状成分，这些成分从绒毛的末端和侧面延伸到整个基质中，并在那里紧密排列。纤维状成分束与滋养母细胞的表膜形成连接。在超微结构上，驴的肉孢子虫属与先前从马中描述的肉孢子囊相似。
