One of the methods to identify species that infect humans morphologically is microscopic examination of the gravid proglottid and the scolex. By counting the number of uterine branches in a gravid proglottid, the species of can be identified. According to literatures, the number of uterine branches of proglottid varies between 11 - 31 and the scolex has a rostelum and apical pit without hooklet.
The aim of this study was to identify the morphology of scolex, to see the presence of rostelum, hooklet, oral sucker, and apical pit using SEM.
We investigated 19 gravid proglottids of from Simalungun District, North Sumatra Province using dissecting microscope examination and one scolex using light microscope and scanning electron microscope (SEM).
The findings showed that the number of uterine branches of the gravid proglottid was 16, and neither rostelum nor apical pit in the scolex was found. However, a curved shape at the apex of the scolex was identified and named as snout.
The number of uterine branches of that was found in Simalungun District, North Sumatra Province was 16 and the morphology of the scolex was slightly different from that was reported previously. We suggest that the morphology of should be further reviewed, probably of the differences in morphology of according to its endemic area.
鉴定感染人类的物种的方法之一是对孕节和头节进行微观检查。通过计算孕节中的子宫分支数，可以鉴定 的种类。根据文献记载，孕节子宫分支的数量在 11-31 之间，头节具有无小钩的吻突和顶凹。
本研究的目的是通过扫描电镜观察头节的形态，观察吻突、小钩、口吸盘和顶凹的存在。
我们使用解剖显微镜检查了来自北苏门答腊省锡马伦巩区的 19 个孕节，并使用光学显微镜和扫描电子显微镜（SEM）检查了一个头节。
结果显示，孕节的子宫分支数为 16，头节既没有吻突也没有顶凹。然而，在头节的顶端发现了一个弯曲的形状，我们将其命名为吻突。
在北苏门答腊省锡马伦巩区发现的 的子宫分支数为 16，头节的形态与之前报道的略有不同。我们建议进一步审查 的形态，可能是由于其流行地区的形态差异。
