Scanning electron microscopy was used to study the surface characteristics of the oocyst, sporoblast and sporozoite of Plasmodium yoelii yoelii. Observations were made of the sporogonic stages of 6-12 day infections of the malaria parasite in Anopheles stephensi. Oocyst and sporoblast development were not synchronous. The surface of the undifferentiated (early stage) oocyst appeared smooth, whereas that of differentiated (late stage) oocysts were rough or wrinkled. The wall of the differentiated oocysts showed numerous micropores at higher magnification (x15,000-20,000) the biological significance of which is not known. Small, bud-like satellite bodies were seen attached to some oocysts. Various forms of different stages of the sporoblast were described. Sporozoite budding took place on the surface of the sporoblast body. The sporozoite was elongate, curved and with a blunt anterior end.
利用扫描电子显微镜研究约氏疟原虫约氏亚种卵囊、子孢子母细胞和子孢子的表面特征。对斯氏按蚊体内感染6 - 12天的疟原虫孢子生殖阶段进行了观察。卵囊和子孢子母细胞的发育不同步。未分化（早期）卵囊的表面看起来光滑，而分化（晚期）卵囊的表面粗糙或有皱纹。在高倍放大（15000 - 20000倍）下，分化卵囊的壁显示出许多微孔，其生物学意义尚不清楚。可见一些卵囊附着有小的芽状卫星体。描述了子孢子母细胞不同阶段的各种形态。子孢子在子孢子母细胞体表面出芽。子孢子呈细长形，弯曲，前端钝圆。
