摘要: 本文用扫描电镜观察约氏疟原虫动合子形成的过程。首先从合子一端伸出指状或棒状突起,突起顶端呈平截状圆锥形,随着突起伸长、变粗,合子本体逐渐皱缩变小,最终形成残余体。在新形成的动合子和合子本体的残余体之间增厚,并由此断离。在动合子形成期间虫体运动活跃.出现向前伸长和扭曲运动。成熟动合子表面光滑,呈香蕉形或腊肠形.虫体前端为顶端复合体,在前端截状圆锥体后因弯曲、收缩活动而出现多个表膜皱折。动合子本身有扭曲运动,因而虫体表面出现螺旋状皱纹。

Abstract: The ookinete formation and mature ookinete of Plasmodium yoelii yoelii were described. During the development from zygote to ookinete, at first a finger-shaped or a stick-shaped projection protruded from one side of zygote (Fig. l).The anterior end of the projection assumed a truncated cone shape (Figs. 1-5). Following enlargement of the projection, the body of zygote gradually wrinkled and shrank and became smaller (Figs. 2-5). An annular structure developed between the newly formed ookinete and the remaining body of zygote (Figs. 5-6), which ultimately separated from the ookinete.Tile ookinete was banana-shaped. The surface of mature ookinetes was smooth (Fig. 13). On the tip there was an apical complex showing truncated cone shape. Behind the apical end there were a few pellicular folds (Figs. 9-11).Through the course of development of the ookinete the parasite constantly showed obvious movement. As the parasites protruding forward, longitudinal and spiral wrinkles appeared on their body surface (Figs. 2-4, 10-12).
