摘要
透射电镜观察虫体纵切面呈圆形或卵圆形。体前1/3有一椭圆形细胞核,在核与副基纤维的背侧有高尔基复合体。体前的毛基体复合体由鞭毛周管、管壁内“C”形盾结构及5个毛基体三部分组成。由毛基体分别发出4根前鞭毛及1根后鞭毛,同时还发出1根肋和2根副基纤维。轴柱分头、干、尾三部分,匙形轴头来自盾-轴连合处,围绕细胞核一侧向虫体后端延伸,至核末端扭转成筒状轴干,最后成针状伸出体外。
In longitudinal sections, T. vaginalis visualized by TEM was round or ovoid with an ovoid nucleus situated close to the anterior one-third of the body. There was an independent and well-developed Golgi complex dorsal to the nuleus and parabasal filaments. The anterior end of the cell had a blepharoplast complex which consisted of three parts, i.e., periflagellar canal, C-shap&d structure of the pelta in the wall of periflagellar canal and five blepharoplasts. Four anterior flagella and one posterior flagellum were extended respectively from each of the blepharoplasts, simultaneously with one costa and two parabasal filaments. The axostyle was divided into three parts, i.e., capitulum, trunk and caudal. The spoon-shaped axostylar capitulum originated from the peltar-axostylar junction was composed of many microtubules and extended around the side of the nucleus posteriorly and turned itself at the end of the nucleus forming an axostylar trunk which projected externally in the form of a spicule (Figs.1-9).
