Abstract:
Freshwater snails (family Paludomidae, genus Paludomus) were collected from streams in Hedeniya and Peradeniya (the campus of Peradeniya University), Kandy district, Central Province, Sri Lanka, and found to harbor rediae and cercariae of a Paragonimus sp. These larvae were identified as Paragonimus westermani by using ITS2 DNA sequences. The infection rates of P. westermani in Paludomus sp. in Hedeniya and Peradeniya were 0.1% (one of 1014) and 0.2% (two of 1006), respectively. The snail has not been identified to species in the present study. This is the first report of the snail host of Paragonimus in Sri Lanka.
