Complement activation did not substantially affect the tegument integrity after 18 h of complement exposure. Cercaria and 18 h-cultured schistosomula were exposed to normal human serum for 18 h. Cercariae (a) and schistosomula (c) were stained with anti-neoC9 antibody. Cercariae (b) were labeled with Hoechst dye. Note that the tegument of both cercarial bodies and schistosomula is fluorescent after labeling with anti-neoC9. Tails but not bodies of cercariae show fluorescent labeling with Hoechst dye. Scale bars are 50 μm in a 10× magnification field
