Summary

A stereological study was undertaken on the length, diameter and numbers of microtriches and on the structural and functional amplification factors of the adult cestodes, Hymenolepis diminuta, Hymenolepis nana, Eubothrium crassium, Proteocephalus pollanicoli, the plerocercoid of Schistocephalus solidus and the cysticercus of Taenia crassiceps. The study showed wide variations in these stereological parameters between species, stages and regionally in the same species. A comparison of the present results with previous studies has shown a large measure of agreement but some differences are evident and possible explanations of these differences are proposed.
