Abstract

Moniezia expansa could be considered as the most important cestode parasites infecting sheep causing monieziasis which constitutes a problem in sheep breeding. The aim of the present study is to investigate on the anatomical cellular and tissue structure and development of the interproglottidal gland and tegument correspondig to the mechanism of its secretion. The detailed structures of the tegument and microtriches could not be seen by light microscoy examination and also the interproglottidal glands appear as interupted non differential cellular chain in between worm proglottides or segments. The ultrastructure study done by transmission electron microscopy (TEM) revealed that the glands develop separately from the tegument and compromising an endocrine character. It was observed that the gland consists of subglobular follicles or vesicles, which are embedded in parenchyma and pushing the tegument at the posterior border of the proglottid, formulated crypt-like structures with central hilum or sinus. The gland secretions were diffused to the tegument and parenchyma of the proglottid through cellular channels (protoplasmic channels) upward to the anucleate syncytial layer of tegument; apical cytoplasm through cytoplasmic channels.
