应用冷冻断裂技术研究了弓形虫和肉孢子虫的感染期。表膜外膜连续，在P破裂面顶端形成8 + 1的颗粒花结。内膜复合体由矩形扁平囊泡组成，排列成纵行，并以拼图般的方式连接。肉孢子虫有11行，而它们的数量在弓形虫中各不相同。存在后部中断。前面，1截锥形板顶部打开的垂直脊。膜的内部复杂的特点是平行排列的颗粒（在P面），其中一些加入连续的双行辐射在顶帽。这些行在数量和排列上与下面的微管相对应。棒状体呈周期性的圆形颗粒阵列。
Infective stages of Toxoplasma and Sarcocystis were studied by the freeze fracture technique. The outer membrane of the pellicle was continuous and showed an apical 8 + 1 particles rosette in the P fracture face. The inner membrane complex was made of rectangular flattened vesicles aligned in longitudinal rows and joined in a puzzle like fashion. Sarcocystis had 11 of these rows whereas their number varied in Toxoplasma. A posterior interruption was present. Anteriorly, 1 truncated conical plate apically opened by a vertical ridge. The membranes of the inner complex were characterized by parallel alignment of particles (in P faces) some of which were joined continuous with double rows radiating in the apical cap. Those rows corresponded in number and arrangement with the underlying microtubules. The rhoptries showed periodic circular particle arrays.
