Abstract
- Laboratory rats fed sporocysts of Sarcocystis singaporensis (Zaman & Colley, 1975) Zaman & Colley, 1976 originating from Singapore were euthanized 22, 23, 33 and 80 days later. Sporocysts were extracted from feces of either naturally or laboratory-infected Python reticulatus. Electron microscopically examined tongue and esophageal muscles yielded images of successive developing stages of sarcocysts. The primary wall evolved from a continuous thin layer into folds and later, into villar protrusions. At all stages the wall was interrupted by pinocytotic-like indentations. Young sarcocysts contained only metrocytes, they divided by endodyogeny into daughter metrocytes. The first bradyzoites appeared only 33 d.p.i. Sarcocysts by 80 d.p.i. were enclosed in a fully differentiated primary wall and contained almost entirely bradyzoites.
