Globidian parasites infecting the abomasum of sheep in Germany were investigated by means of electron microscopy. The frequency of infection was found to be 93 % The globidian cyst-like bodies contained multinucleate schizonts, developing merozoites or fully developed merozoites. Among the latter there were two different types, namely short and long forms. The process of merozoite formation was described in detail. The giant schizonts were subdivided into multinucleate cell portions of irregular size and shape. Their nuclei were then arranged at the periphery of the cell portions and underwent their last division which was combined with the differentiation of merozoites. The long form merozoites were elongated cylindrical in shape with terminal nucleus. They measured 7.7 μm in length and 1.0 μm in width. The merozoites of the short type were spindle-shaped with a central nucleus. They were 5.0 μm long and 1.0 μm wide. The globidian parasites were located in a parasitophorous vacuole of an intact host cell.
利用电子显微镜对德国感染绵羊皱胃的球虫寄生虫进行了研究。发现感染率为93%。球虫样囊肿体包含多核裂殖体、正在发育的裂殖子或完全发育的裂殖子。在后者中存在两种不同类型，即短型和长型。详细描述了裂殖子的形成过程。巨大裂殖体被细分为大小和形状不规则的多核细胞部分。然后它们的细胞核排列在细胞部分的周边，并进行最后一次分裂，这与裂殖子的分化相结合。长型裂殖子呈细长圆柱形，有末端细胞核。它们长7.7μm，宽1.0μm。短型裂殖子呈纺锤形，有一个中央细胞核。它们长5.0μm，宽1.0μm。球虫寄生虫位于完整宿主细胞的寄生泡中。
