Schistosoma haematobium (Egyptian strain) transmission microscopy of normal and praziquantel treated worms.
The ultrastructure of the tegument and subtegumental structures of S. haematobium worms was examined by TEM. The effect of praziquantel on residual worms which remained after a curative dose was also studied. The male S. haematobium worms were characterized by deep tortuous pits and sharp apically directed spines. Spherical and elliptical bodies were also observed. The esophageal tegument was described. The effect of praziquantel on the male worms revealed flattening of spines and their disappearance in some regions as well as disruption and vacuolization of the tegument in others.
