Life cycles and illustrations of the different developmental stages of S. mansoni, E. paraensei and D. potomaca in iM line B. glabrata. Shown for each parasite species used is an intramolluscan life cycle with different life cycle stages connected by arrows, and the approximate times post-infection indicated (2, 8 and 40 days post-infection). Presence of developing parasites of the expected species was confirmed in all parasite-exposed species (see text)
