ABSTRACT:
Fascioliasis vaccine, especially for bovine administration, can be prepared by gamma irradiation of Fasciola gigantica metacercariae which can be obtained by infecting Lymnaea natalensis snails with Fasciola gigantica miracidia and growing the snails until they shed cercariae which encyst to become metacercariae.
