Rearing of the snail Biomphalaria glabrata under axenic conditions in isolators

Germfree Biomphalaria glabrata were successfully reared through their life cycle in isolators. The snails were fed a diet sterilized either by heat or by irradiation. Snails fed an irradiated diet had a better growth and higher reproduction rate than the ones fed an autoclaved diet. There was no difference in survival between the two groups.
