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.
