Abstract: AIM:To observe the lesion of tegument of Oncomelania snails treated with seed of
Camellia Sinensis(SCS) .METHODS:Using scanning electron microscopy for observation of damage in
the tegument of normal and infected Oncomelania snails treated with SCS.RESULTS:Tegument of
head in drug treated snail showed serious damage and deformity.Part of snail foot was thickened
and wrinkled,infiltrated with numerous cells.Fine and soft microfilament tissue in the lateral
border of mantle in normal Oncomelania snails were demonstrated. After exposure to the drug, normal tissue of mantle was destroyed. The visceral sac at liver site in infected snail showed severe damage (Figs. 1- 14). CONCLUSION: The tegument of soft tissues of Oncomelania hupensis would be damaged by SCS.
