Ultrastructural studies of the surface of hymenolepis nana by scanning and transmission electron microscopy

ABSTRACT

Scanning electron microscopy of the surface of Hymenolepis nana indicated that dense populations of microtriches occur on scolex proper, suckers and strobila, with an average density of 20/um[2]. The excellent preservation of microtriches proves the efficacy of the critical point drying method for preparing cestodes for study of SEM. The cytological structure of the tegument of H. nana corresponds general to that of other tapeworms
