Light and electron microscope investigations were carried out on the infection with Trypanosoma (Nannomonas) congolense of laboratory-reared tsetse flies Glossina pallidipes. Trypanosomes became entombed in the peritrophic membrane (PM) to form intraperitrophic cavities which were more electron-translucent than the amorphous layer of the PM. A hypothesis is suggested that after migration anteriorly in the ectoperitrophic space, the trypanosomes become enmeshed in the PM during its formation in the proventriculus, and that the trypanosomes are extricated in the midgut as the PM advances towards the posterior end of the gut.
对实验室饲养的淡足舌蝇（Glossina pallidipes）感染刚果锥虫（Trypanosoma (Nannomonas) congolense）进行了光学显微镜和电子显微镜研究。锥虫被困在围食膜（PM）中形成围食膜内的腔，这些腔比围食膜的无定形层电子透明度更高。提出了一个假说，即锥虫在外围食膜空间向前迁移后，在嗉囊形成围食膜的过程中被围食膜缠住，并且随着围食膜向肠道后端推进，锥虫在中肠被释放出来。
