Oocysts and sporocysts of T. gondii were examined with the scanning electron microscope. The oocysts were slightly ellipsoidal in shape with a smooth outline. The sporocysts were also ellipsoidal with a smooth surface on which there were a number of raised ridges. The ridges represent the junctions between the four plates comprising the sporocyst wall. From the distribution of the ridges it was concluded that the wall consisted of two upper and two lower plates which were at an angle to each other and which interlocked along the mid-line suture. The specific orientation of the plates would provide a structure extremely resistant to mechanical disruption. During excystation, an infolding of the surface was observed along the suture lines between the plates of the sporocyst wall.
用扫描电子显微镜对刚地弓形虫的卵囊和子孢子囊进行了检查。卵囊形状略呈椭圆形，轮廓光滑。子孢子囊也是椭圆形，表面光滑，有许多凸起的脊。这些脊代表构成子孢子囊壁的四块板之间的连接处。从脊的分布可以得出结论，壁由两块上板和两块下板组成，它们相互成一定角度，并沿中线缝合处相互嵌合。板的特定取向将提供一种极具抗机械破坏能力的结构。在脱囊过程中，观察到子孢子囊壁板之间的缝合线处表面有内褶。
