Extract

Two major cytoplasmic inclusions, multilaminate vesicles and discoid granules, are present in the tegument of Schistosoma mansoni. These are produced at separate Golgi apparatuses in the tegument cell bodies and move up to the surface by a combination of diffusion and fluid flow. The discoid granules contain neutral mucopolysaccharide and are believed to break down to form the ground substance of the tegument. The multilaminate vesicles are rich in phospholipid and the contents, at least superficially, resemble unit membranes. The multilaminate vesicles are believed to contribute their contents to the multilaminate surface of the worm which appears to be continually replaced. These observations are related to current ideas on membrane turnover and the ability of the worm to acquire a disguise of host erythrocyte glycolipid.
