Effect of schistosome infection on protein, glycogen and glucose contents in biomphalaria arabica and bulinus truncatus

ABSTRACT

B. arabica and B. truncatus the snail intermediate hosts of intestinal and urinary schistosomiasis in Yemen Arab Republic, were bred in the laboratory and infected with S. mansoni and S. haematobium, respectively. Schistosome infection caused a marked decrease in the glycogen and protein contents in the tissue of B. arabica and B. truncatus. The glucose content in the hemolymph of both infected snails was lower than that in the normal snails
