The anterior tail chamber and survival of Gorgoderina vitelliloba

Mitchell J. B., Mason A. R. and Whalley A. J. S. 1980. The anterior tail chamber and survival of Gorgoderina vitelliloba. International Journal for Parasitology10: 181–182. Survival in pond water of intact cystocercous cercariae of Gorgoderina vitelliloba was significantly better than that of isolated cercarial bodies, although the latter were able to survive in Ringer's Solution. Survival of cercarial bodies in water was improved somewhat when sterility was maintained. It is suggested that the wall of the anterior tail chamber protects the body from the osmotic stress imposed by life in fresh water.
