本文研究了卡氏阿米巴Neff株滋养体的微细结构。运动伪足、尖刺状的“刺足”和细胞表面的微突起都是由透明的细胞质形成的，它排除了细胞的有形成分，含有细纤维状物质。描述了高尔基复合体、平滑和粗糙的内质网、消化泡、线粒体和排水囊泡（收缩泡）。一个管状系统开口到水驱逐囊泡包含小管直径约600埃，内衬与丝状材料。小管是连续的，有无衬里的囊泡或直径较大的壶腹。中心粒没有观察到，但细胞质微管辐射从一个致密的材料类似于中心粒卫星，并经常集中在高尔基复合体。细胞质储备物质包括脂质和糖原，每种物质约占干重的10%。
The fine structure of the trophozoite of Acanthamoeba castellanii (Neff strain) has been studied. Locomotor pseudopods, spikelike "acanthopodia," and microprojections from the cell surface are all formed by hyaline cytoplasm, which excludes formed elements of the cell and contains a fine fibrillar material. Golgi complex, smooth and rough forms of endoplasmic reticulum, digestive vacuoles, mitochondria, and the water-expulsion vesicle (contractile vacuole) are described. A canicular system opening into the water-expulsion vesicle contains tubules about 600 A in diameter that are lined with a filamentous material. The tubules are continuous with unlined vesicles or ampullae of larger diameter. Centrioles were not observed, but cytoplasmic microtubules radiate from a dense material similar to centriolar satellites and are frequently centered in the Golgi complex. Cytoplasmic reserve materials include both lipid and glycogen, each of which amounts to about 10% of the dry weight.
