Ultrastructure of the cysts of Sarcocystis rangiferi from skeletal muscle of reindeer ( Rangifer tarandus tarandus )
Cysts of Sarcocystis rangiferi from reindeer (Rangifer tarandus tarandus) were examined by transmission electron microscopy. The cysts were located within skeletal muscle cells which were encapsulated by a thick layer of connective tissue. The connective tissue capsule consisted of numerous fibrobla...
