Effect of schistosoma mansoni infection, starvation and molluscacides on acid phosphate, transminases and total protein in tissues and hemolymph of biomphalaria Alexandrina

The activities of GOT and GPT in the hemolymph of B. alexandrina were significantly decreased by S. mansoni infection. However, the total protein concentration and AcP activity were increased. Although the snail starvation decreased AcP activity in the ovotestis, it increased GOT activity in the other organs of the snails. On the other hand, the snail feeding after starvation increased significantly AcP activity in ovotestis. Natural and synthetic molluscicides inhibited the activities of GOT and GPT, however, they increased the total protein concentrations and AcP activities in the examined organs
