Abstract

This study traces the growth rate of Hymenolepis citelli and correlates such growth to the relative frequency of the only mitotically active cell found in the germinative and immature regions of the cestode. The abundance of this cell, termed the germinative cell, was very high during the early logarithmic growth phase of the cestode and decreased just prior to patency to a level that was maintained until day 90 postinfection. An increase in germinative cell frequency was observed at day 90. It is postulated that this increase may reflect a developmental change which has occurred in the cestode following patency.

摘要

本研究追踪了柠檬膜壳绦虫的生长速率,并将这种生长与在该绦虫生发区和未成熟区发现的唯一有丝分裂活跃细胞的相对频率相关联。这种细胞被称为生发细胞,在绦虫早期对数生长期丰度很高,在成熟前下降至一个在感染后90天一直维持的水平。在感染后90天观察到生发细胞频率增加。据推测,这种增加可能反映了绦虫在成熟后发生的发育变化。
