Carbohydrate metabolism in uninfected and trematode-infected snails Biomphalaria alexandrina and Bulinus truncatus



Carbohydrate metabolism in uninfected and trematode-infected snails Biomphalaria alexandrina and Bulinus truncatus



Comparative Biochemistry and Physiology 51B(4): 499-505



The rate of gluconeogenesis was decreased to 62% in Bulinus truncatus infected with Schistosoma haematobium and to 45% in Biomphalaria alexandrina infected with S. mansoni. Lactic acid production was increased in schistosome-infected snails by 52 and 73% of that of uninfected B. alexandrina and Bulinus truncatus, respectively. Infection caused a marked decrease in glycogen content of the tissues of both snail species (75% in B. truncatus and 64% in Biomphalaria alexandrina). The snails' citric acid cycle pathways were affected by infection, especially those concerned with succinic and cytochrome oxidases.
