This study investigated the effects of artificial spring water (ASW), conditioned tap water (CTW), and deionized (DI) water on Biomphalaria glabrata snails infected with the trematode parasite Schistosoma mansoni. Biomphalaria glabrata snails infected with S. mansoni were placed in cultures containing ASW, CTW, or DI for 3 wk during which snail survival and the number of egg masses were recorded. Snails in ASW and DI showed similar survival, whereas all snails in CTW cultures died within 2 d. However, snails in ASW showed better fecundity then did those in DI and had a significantly greater number of egg masses. Despite decreased fecundity, we noted that DI may serve as an adequate cost- and labor-effective replacement for ASW in the laboratory maintenance of B. glabrata infected with S. mansoni.
