Abstract
The snail intermediate hosts of Fasciola gigantica include Radix (Lymnaea)
auricularia and Radix (Lymnaea) luteola are widely distributed in various regions
of Tamil Nadu. These snails were found to be susceptible to experimental infection
with Fasciola gigantica miracidium. A colony of adult R.auricularia and R.luteola
was reared. Various developmental stages of lymnaeid snails from eggs to adult were
studied under laboratory condition. The miracidia were developed from the eggs of
the Fasciola gigantica flukes. The snails were exposed to the miracidia for infection
for 30 days. It was found that snails were negative for any developmental stages
after infection. The miracidium did not infect the snails. It showed that unsuccessful
infection might be due to the variation between strains of F.gigantica and snails.
