Abstract

Prevalences and intensity of infection with third stage larvae were examined in mollusks to determine whether they are potential intermediate hosts in eight provinces, northeast Thailand. Mollusk samples were collected from 24 reservoirs (3 reservoirs/province) in close to human cases during the previous year. Six out of 24 localities and 9 (3 new record species) out of 27 species were found with the infection. The highest intensity in infected species was found to be only one or two snails, whereas the majority had very low or no infection. The highest density was found in and the lowest in . The edible snails, and have the potential to transmit to man. The varying density levels of larvae in infected snails may reflect observed variation in symptoms of people who traditionally eat a raw snail dish.
