The importance of the bladder for the development of the cysticercus

Abstract

The bladder of the cysticerci, the larvae of cestodes, is a transitory embryonic organ; its morphology is related to its mode of development and the localization of the parasite in its intermediate host. The bladder makes possible the adaptation of the cysticercus to unusual conditions of its development. A certain degree of analogy between the trophoblast of the mammalian embryo and the bladder of the cysticerci adapted to the development in the tissues of mammals can be drawn.
