In contrast, the mortality rates of snails in the WPN group, WPN + SHAM group, and WPN + SHAM# groups showed highly significant differences ( P < 0.001) at time points from 6 to 48 h (Additional file 9 : Table S4).

In addition, the distribution of the snail in some areas endemic for schistosomiasis has shown an increasing trend as a consequence of ecological and environmental changes [ 6 , 8 ].
