Oocysts of Eimeria nieschulzi from the laboratory rat, Rattus norvegicus, were studied by scanning and transmission electron microscopy. Oocysts had a rough outer wall with apparent random depressions. The oocyst wall is composed of 2 layers: an osmiophilic outer layer consisting of a rough external and smooth internal surface, and a relatively thick, electron-lucent inner layer. The outer layer is composed of a dense, coarsely granular matrix. The inner layer consists of homogenous fine granular material interspersed with coarse osmiophilic granules and contains one closely applied membrane on the outermost surface. Several raised lenticular areas are seen on the coarse outer surface of the inner layer. These layers are 102 (75-128) and 176 (135-204) nm thick, respectively. The sporocyst wall is thin, consisting of 3 to 4 unit membranes, and measures (18-34) nm thick.
利用扫描电子显微镜和透射电子显微镜对来源于实验大鼠褐家鼠的尼氏艾美耳球虫卵囊进行了研究。卵囊具有粗糙的外壁，有明显的随机凹陷。卵囊壁由两层组成：一层嗜锇外层，其外表面粗糙，内表面光滑，以及一层相对较厚的、电子透明的内层。外层由致密的、粗颗粒状基质组成。内层由均匀的细颗粒物质组成，其间散布着粗大的嗜锇颗粒，并且在最外表面含有一层紧密贴合的膜。在内层的粗糙外表面上可见几个凸起的透镜状区域。这些层的厚度分别为102（75 - 128）纳米和176（135 - 204）纳米。孢子囊壁薄，由3至4个单位膜组成，厚度为（18 - 34）纳米。
