EURYTREMA-COELOMATICUM (DIGENEA, DICROCOELIIDAE) - THE EFFECT OF INFECTION ON CARBOHYDRATE CONTENTS OF ITS INTERMEDIATE SNAIL HOST, BRADYBAENA-SIMILARIS (GASTROPODA, XANTHONYCHIDAE)

The interface Eurytrema coelomaticum/Bradybaena similaris was studied by quantifying the amount of glucose on the hemolymph and the content of glycogen in the cells of the digestive gland and the cephalopedal m ass of infected and uninfected snail Samples were analyzed on days 0, 30 90 and 150 post-infection The infected snail had less glucose in th e hemolymph: with a reduction of 67.05% at 30 days, and 62.09% at 90 d ays post-infection. The reduction in glycogen content was 86.41% in th e digestive gland and 79.1% in the cephalopedal mass at 30 days, and 9 2.71% and 90.89% in these organs respectively at 90 days post-infectio n It is proposed that the sporocysts absorb glucose directly from the hemolymph.
