title: [The cytochemical study of polysaccharides in coccidia of the genus Sarcocystis. I. Sulfated glycosaminoglycans in Sarcocystis muris sarcocysts].
abstract: An electron microscope study of sulfatized glycosaminoglycans (SG) was made for cyst stages of S. muris. The polysaccharides were detected in the submembranous and subwall layers of the sarcocysts, in addition to the ground substance and septae. Moreover SG were discovered in the cyst stages themselves--metrocytes, intermediate cells and merozoites (gamonts). SG were discernible as electron dark spots in vacuoles of the metrocytes. SG shaped as granules were scattered in the cytoplasm of both intermediate cells and merozoites. More granules of SG were seen in the cytoplasm of the merozoites compared to the intermediate cells. Thus, the quantity, localization and structure of SG are seen to follow the process of differentiation in muscle cysts of S. muris.
