Impact of S. mansoni infection on laccase activity in the hemolymph of B. glabrata, across the infection (9 weeks). PO activity was measured as the amount of dopachrome formed from the oxidation of PPD substrate (50 mM), with and without trypsin as protease activator, 2 h after the substrate addition. Total (with trypsin activation) and intrinsic (without trypsin activation) laccase activity are shown in solid and dotted lines respectively. Grey lines refer to uninfected control snails and black lines to infected snails. S. mansoni has a strong impact on snail laccase activity (both total and intrinsic). This effect was not immediate but appeared after 6 weeks of infection
