Abstract：
:Discoid granules were isolated from the tegument of adult Schistosoma mansoni by differential centrifugation of freeze-thaw extracts. Comparison of proteins and glycoproteins from discoid granules, surface membranes and the soluble fraction implied that discoid granules and the surface membrane were functionally linked. The results are discussed in terms of discoid granule function and surface membrane organisation.
