The ultrastructure is described of the meronts, microgamonts and young oocyst stages of Isospora hemidactyli of the gecko Hemidactylus mabouia from Belém, PA, north Brazil. The endogenous stages all develop in the nucleus of the gut epithelial cells. The nucleus remains intact up to the latest stages of the parasite's development, but degenerates by the time the oocyst appears. Merogonic division appears to be asynchronous, and some of the differentiated merozoites contained more than one nucleus. Microgamonts conform in structure with those of other eimeriids. Some of the type 2 wall-forming bodies disintegrate into smaller globules and ground substance of lower density.
描述了来自巴西北部帕拉州贝伦的半叶趾虎（Hemidactylus mabouia）的半叶等孢球虫（Isospora hemidactyli）的裂殖体、小配子体和年轻卵囊阶段的超微结构。内源性阶段均在肠道上皮细胞核内发育。直至寄生虫发育的最晚阶段，细胞核仍保持完整，但在卵囊出现时会退化。裂体生殖分裂似乎是异步的，一些分化的裂殖子含有不止一个细胞核。小配子体在结构上与其他艾美耳科原虫的小配子体一致。一些2型成壁体解体成较小的球状体和密度较低的基质。
