Abstract:
The red-eared slider turtle (Trachemys scripta elegans) was intentionally introduced from the United States to Japan as a pet in the 1950s and has become established throughout much of the country. We examined red-eared slider turtles from two localities in Japan for foreign parasitic helminths. Consequently, a total of seven species of helminths were found: two monogeneans (Neopolystoma exhamatum and Polystomoides japonicum), three digeneans (Spirorchisartericola, Spi.elegans and Telorchis clemmydis) and two nematodes (Serpinema microcephalum and Falcaustra wardi). Of these, three helminths are alien to Japan-Spi.artericola, Spi. elegans and F. wardi-which represent the first report of their presence in the red-eared slider turtle from Japan.
