Excretory-secretory proteins released by Schistosoma mansoni-resistant, susceptible and naïve Biomphalaria glabrata

Schistosomiasis is one of the most socioeconomically harmful neglected tropical diseases in the world. It occurs following infection from parasites of the Schistosoma genus, such as Schistosoma mansoni, which must transition within a molluscan and mammalian host to survive. Previous chemical analyses of schistosome-molluscan interactions indicate that schistosomes orientate towards potential hosts partially through chemosensation, displaying a preference for naïve (uninfected) hosts. Recent advances in proteomic techniques enable sophisticated comparative analyses between infected and naïve snail host proteins. This study aimed to compare the snail-conditioned water (SCW) released by F1 resistant, infected and naïve Biomphalaria glabrata to identify potential attractants and deterrents.
