Ultrastructure of the Cysts of Sarcocystis Tarandivulpes from Skeletal Muscle of Reindeer (Rangifer Tarandus Tarandus)
The cysts of S. tarandivulpes were found to be limited by a unit membrane which has been called the cyst membrane. The surface of the cysts was covered by closely packed and hexagonally arranged knob-like protrusions. The protrusions were 0.6–1.2 μm long and had an elliptical cross section. At the b...
