Abstract
The morphology and ultrastructure alterations
of the digestive gland, as well as biochemical
changes of Pirenella conica infected with
Heterophyes larvae were investigated in
snails collected from irrigation canals in Port-
Said Province during the spring-summer
periods of 2012-2013. The results showed
great histological damages in the digestive
gland of infected snails. Meanwhile, a
significant decrease (P ≤ 0.05) i n total protein
and total lipid contents was detected while the
glucose concentrations exihibited a small
range of variation. Uric acid was significantly
increased in both the digestive gland and the
cephalopedal mass. Infected snails showed
elevated levels (P 0.05) of nitric oxide and
the antioxidant enzymes; superoxide
dismutase (SOD) and glutathione Stransferase
(GST).
