Developmental expression of SmATPDase1 (a) and SmATPDase2 (b) as determined by qRT-PCR (mean ± SD, n = 3) in the following life cycle stages: egg, cercaria, schistosomulum, and adult male and female. Data are expressed relative to adult males, set at 1. For SmATPDase1, all stages are significantly different from all other stages (P < 0.05) except egg versus cercariae and schistosomulum versus female. For SmATPDase2, all stages are significantly different from all other stages (P < 0.05) with the exception of schistosomulum v male. The data shown are representative of three independent experiments
