In Thailand, many species of freshwater snails
were reported to be intermediate hosts. For example, M. tuberculata, Melanoides jujicostis and Neoradina
prasongi are the intermediate hosts of Haplorchis
taichui and Haplorchis pumilio[8]. Other snail species, Filopaludina spp. and Lymnaea spp. were reported to
act as the first and second most common intermediate
hosts of trematodes in the family Echinostomatidae[9].
Furthermore, the planorbis snails are intermediate
hosts of blood fluke in family Schistosomatidae[10,11].
