The development of the macrogamete of Eimeria mivati Edgar and Seibold 1964 was studied with the electron microscope. Development of the young gamont was characterized by a loss of organelles such as the apical complex, subpellicular microtubules, rhoptries and micronemes, followed by an increase in micropores, mitochondria, rough endoplasmic reticulum (rER), and Golgi complexes. Nuclear detachment bodies and canaliculi were present in maturing macrogamonts. Amylopectin was first observed as small electron-dense rod-like bodies that eventually became large electron-transparent bodies. Type II wall-forming bodies developed in the cisternae of the rER. Type I wall-forming bodies appeared shortly thereafter in close association with numerous Golgi complexes. Many small vesicles located between the cisternae of the rER and the Golgi complexes formed what appeared to be a secretory pathway whereby protein formed in the cisternae and, modified by the Golgi complex, may produce the type I wall body material. The outer wall of the oocyst developed between two distal membranes on the surface of the macrogamete. Although the actual mechanism of deposition of the wall material was not seen, it was probably by some secretory process. Wall-forming bodies did not fuse.
利用电子显微镜对1964年埃德加和赛博尔德发现的米氏艾美耳球虫大配子的发育过程进行了研究。幼配子体的发育特征为细胞器丢失，如顶复合器、表膜下微管、棒状体和微线体，随后微孔、线粒体、粗面内质网（rER）和高尔基体数量增加。成熟大配子体中存在核脱离体和小管。支链淀粉最初表现为小的电子致密棒状体，最终变成大的电子透明体。II型壁形成体在rER的潴泡中发育。I型壁形成体随后不久出现，与众多高尔基体紧密相连。许多位于rER潴泡和高尔基体之间的小泡形成了一条看似分泌途径，在潴泡中形成并经高尔基体修饰的蛋白质可能在此产生I型壁体物质。卵囊外壁在大配子体表面的两个远端膜之间发育。虽然未观察到壁物质沉积的实际机制，但可能是通过某种分泌过程。壁形成体不融合。
