The completed life-cycle of Cyclospora talpae, an extra-intestinal coccidian (Apicomplexa) of the liver of the mole (Talpa europaea), is reported. Oocysts sporulated within 12-14 days at room temperature (20-22 degrees C). Both macro- and microgametocytes developed independently within the nucleus of epithelial cells lining the bile duct as demonstrated by both light and electron microscopy. Merogony was seen in the mononuclear cells in the capillary sinusoids of the liver. Merozoites showed the typical ultrastructural features of the Apicomplexa. The life-cycle of C. talpae and the ultrastructure of the gametogonic and merogonic stages are reported; the ultrastructure of the merozoites is reported as the first description of this stage for the genus Cyclospora.
报道了鼹鼠（欧洲鼹鼠）肝脏内一种肠道外球虫（顶复门）——塔尔帕环孢子虫完整的生命周期。卵囊在室温（20 - 22摄氏度）下12 - 14天内孢子化。光学显微镜和电子显微镜均显示，大配子母细胞和小配子母细胞均在胆管内衬上皮细胞核内独立发育。在肝脏毛细血管窦的单核细胞中可见裂体增殖。裂殖子表现出顶复门典型的超微结构特征。报道了塔尔帕环孢子虫的生命周期以及配子生殖和裂体生殖阶段的超微结构；裂殖子的超微结构报道为环孢子虫属该阶段的首次描述。
