Schematic representation of Schistosoma intramolluscan larval stages; miracidia, primary (mother) sporocysts, secondary (daughter) sporocysts and cercariae. For each larval stage, specific biological functions corresponding to predominant up-regulated transcripts (black lettering) or proteins (red lettering) are described. Functional categories of differentially-expressed excretory-secretory proteins/products (ESPs) and larval transformation proteins (LTPs) released inside the molluscan intermediate host during miracidium-to-sporocysts transformation, and cercarial ESPs release during and following emergence from the snail host are also listed (red lettering).
