The First Survey for Helminths Parasitic in Hybrid and Introduced Giant Salamanders, Genus Andrias (Amphibia: Caudata: Cryptobranchidae) in Kyoto, Japan

The first survey was conducted for helminth fauna of hybrid giant salamanders (hybrids between Andrias japonicus and other congeneric species), introduced A. davidianus in Kyoto Prefecture, Japan. Three nematode species, Spiroxys hanzaki, Amphibiocapillaria tritonispunctati Falcaustra sp., one trematode Liolope copulans, were recovered from their alimentary canals. These results show that species are commonly infected with similar to those previously reported infect japonicus. We conclude the spillback native parasites has occurred Prefecture. This study is also record parasitizing
