Toxoplasma gondii tachyzoite was crescent-shaped. The pellicle of the parasite consisted of two membranes. The anterior end contained the polar ring and conoid, the former being the thickened inner membrane and the latter a cylindrical organelle which was made up of about 10 filaments arranged in an oblique row. The subpellicular microtubules numbering 22 originated at the polar ring and extended to the posterior end. The rhoptries extended from the conoid and terminated anterior to the nucleus with a narrow dense neck and an enlarged posterior portion with a glandular structure. The rhoptries perhaps had a secretory function and the conoid might be related to the invasion of the tachyzoite into the host cell.
刚地弓形虫速殖子呈新月形。寄生虫的表膜由两层膜组成。前端包含极环和类锥体，前者是增厚的内膜，后者是一个圆柱形细胞器，由大约10根呈斜排排列的细丝组成。22根表膜下微管起源于极环并延伸至后端。棒状体从类锥体延伸，在细胞核前方终止，有一个狭窄的致密颈部和一个带有腺状结构的扩大的后部。棒状体可能具有分泌功能，类锥体可能与速殖子侵入宿主细胞有关。
