Transmission electron micrographs of cyst of S. cruzi from the heart of Bos taurus coreanae. (A) A high concentration of bradyzoites is enclosed by a thin cyst wall and septa. (B) The micronemes and septa. (C) The cyst wall. Cyst wall protrusions are adjacent to the sarcoplasm of host cell. (D) The magnified protrusion (circle). Microfilaments are not found in the protrusion. (E) The micronemes and nucleus. (F) The cross sectioned anterior region of bradyzoite containing several rhoptries. In addition to several rhoptries, amylopectin granules are presented in abundance. A, amylopectin granule; CW, cyst wall; GS, ground substance; MN, micronemes; N, nucleus; P, protrusion; R, rhoptry; S, septa; SP, sarcoplasm; HC, host cell.
