Extract

Morphological features of the bladder wall of Cysticercus fasciolaris and carbohydrate analysis of the contained fluid are described. The bladder fluid was found to have a higher concentration of glucose than the plasma of the respective host animal. The bladder wall has a prominent duct system with numerous cytoplasmic extensions and interconnections. It is suggested that the bladder may function in the nutrition of the developing cysticercus by providing a reservoir of raw material which may be utilized by the growing strobila.

The authors wish to thank Dr Theodor von Brand for many helpful discussions, and Dr Harley G. Sheffield and Mr Ned M. Etherington for their advice and technical assistance in the preparation of the electron micrographs.
