Effect of Echinostoma liei infection on alterations of protein content and some enzymes in Biomphalaria alexandrina snails.
The survival rate and fecundity of B. alexandrina were greatly reduced when exposed to E. liei miracidia. Also, exposure of B. alexandrina snails to E. liei miracidia induced a disruption in the snail metabolism and this effect was more pronounced in 20-days post-miracidial exposure group than in 10-days group. Protein content was significantly reduced in all exposed snail groups than in the control group. A significant elevation in the levels of aspartate aminotransferase (AST) and alanine aminotransferase (ALT) enzymes was recorded also in exposed snails than unexposed ones (control snails). The results indicated also that there were significant increases in the levels of acid and alkaline phosphatases enzymes in exposed snails.
