title: Myocardial sarcocystosis in a grand eclectus parrot (Eclectus roratus) and a Moluccan cockatoo (Cacatua moluccensis).
abstract: Cardiac sarcocystosis is described in a grand eclectus parrot and a Moluccan cockatoo. Many cysts containing metrocytes were observed within cardiac muscle fibers on tissue sections stained with hematoxylin and eosin. Characteristic ultrastructural features of the cyst walls included the presence of villous projections containing microtubules. Compartmentalization of the cysts resulted from inward extensions of the cyst wall. The differential diagnosis of sarcocystosis, the life cycle of the parasite, and control measures are discussed.
