Summary
The effects of praziquantel, a novel antischistosomal compound, on the activity of adultSchistosoma mansoni (Liverpool strain) in vitro were investigated.
Worm activity was modified at all concentrations of praziquantel. High concentrations (above 0.5 μg/ml) produced rapid paralysis, whilst low concentrations of praziquantel stimulated worm activity. It is concluded that such activity modification could lead to worm displacement in vivo.
