Abstract
Summary
Details of a technic are presented by means of which newly-hatched, bacteriologically sterile snails (Australorbis glabratus) can be secured for study. Snail eggs containing mature embryos are separated manually from the egg-mass, disinfected externally with dilute sodium hypochlorite, and isolated in sealed tubes containing a suitable salt solution and antibiotics. Using this procedure, 90–100% hatch occurs within 3–4 days of treatment, and tests have shown that only a negligible proportion are bacteriologically contaminated. Details of maintenance, behavior, and longevity of these snails are discussed.
