title: Schistosoma mansoni: the presence and ultrastructure of vitelline cells in adult males.
abstract: The presence of vitelline cells in male Schistosoma mansoni from both mixed ans single sex infections in mice is described. Ultrastructurally these vitelline cells resemble the mature, Stage 4 cells from normal female worms. As yet no developing vitelline cells (Stages 1 to 3) have been found. The cells do not appear to form complete lobules as in the female.
