Abstract
This chapter includes ultrastructural features of eggs and the other stages including miracidia, cercariae, sporocysts, rediae, metacercariae and adults of echinostomes. Most of the ultrastructural studies reported to date are on the genera Echinostoma Rudolphi, 1809 and Echinoparyphium Dietz, 1909, but include some other genera such as Echinochasmus Dietz, 1909, Isthmiophora Luhe, 1909 and Himasthla Dietz, 1909. The ultrastructure of echinostomes from naturally or experimentally infected mammalian or avian hosts can be seen in fixed specimens prepared for scanning (SEM) or transmission electron microscopy (TEM). In some reports, cytochemical, immunocytochemical or freeze fracture methods were used to localize enzymes, antigens or other materials in worm tissues or cells.
