Gastrointestinal Helminths of Three Species of Limnonectes Frogs (Anura: Dicroglossidae) from Malaysia

Abstract

Three species of dicroglossid frogs from Malaysia were examined for helminths: Limnonectes ibanorum (n = 5), Limnonectes ingeri (n = 5), and Limnonectes leporinus (n = 6). We found 7 species of Nematoda (Amphibiocapillaria bufonis, Cosmocerca ornata, Falcaustra dubia, Orneoascaris sandoshami, Oswaldocruzia sp., Physaloptera sp., Cosmocercinae gen., sp. 1 of Moravec and Sey 1990); 1 species of Cestoda (pleurocercoid); 1 species of Acanthocephala (Pseudoacanthocephalus bufonis); and 1 species of Digenea (Diplodiscus amphichrus). Cosmocerca ornata was the only helminth infecting the 3 dicroglossid species. The most numerous helminth (n = 36) was Cosmocercinae gen. sp. in L. ibanorum. The 3 species of Limnonectes are parasitized by generalist helminths that also infect other species of frogs. Twelve new host records are reported.
