Morphological and Histochemical Adaptations of Trematode Digestion, with Particular Emphasis on Schistosoma mansoni

  • Burton J. Bogitsh
Part of the Comparative Pathobiology book series (CPATH, volume 8)


The morphology of the digestive system of digenetic trematodes has been reviewed by Bogitsh (1975) and Erasmus (1977). In general, the digestive system is divisible into two regions, the foregut and the caecum. The function of the former region appears to be the ingestion and assimilation of exogenous foodstuffs. In this capacity, it is a highly adaptable area, often displaying myriad specializations that increase efficiency. These specializations may include secretory cells such as is observed in Brachycoelium salamandrae (see Bogitsh and Ryckman, 1982), sensory structures as are present in Megalodiscus temperatus (see Bogitsh, 1972), etc. The lining of the foregut is a continuation of the general tegumental surface of the adult worm with an abrupt and sharp demarcation, a septate desmosome, between it and the gastrodermis.
