Abstract

The Ryukyu long-furred rat, Diplothrix legata (Rodentia: Muridae), is an endangered species endemic to the Tokunoshima, Amami-Oshima, and Okinawajima Islands, which are part of Japan's southwestern islands. During the pathological examination of a deceased wild individual from Tokunoshima Island, lymphoma and infection with three nonnative parasites, Angiostrongylus cantonensis (Nematoda: Angiostrongylidae), Trichosomoides crassicauda (Nematoda: Trichosomoididae), and Hydatigera taeniaeformis (Cestoda: Taeniidae), were identified. Among these, A. cantonensis is a zoonotic species, with invasive rats as the final hosts and mollusks as intermediate hosts. Although the presence of A. cantonensis has been widely reported across the southwestern islands of Japan, this is the first record of this species on the Tokunoshima Island. With this study, A. cantonensis infection in wild D. legata is now confirmed in populations from all three islands where this species is found.

期刊介绍： The International Journal for Parasitology: Parasites and Wildlife (IJP-PAW) publishes the results of original research on parasites of all wildlife, invertebrate and vertebrate. This includes free-ranging, wild populations, as well as captive wildlife, semi-domesticated species (e.g. reindeer) and farmed populations of recently domesticated or wild-captured species (e.g. cultured fishes). Articles on all aspects of wildlife parasitology are welcomed including taxonomy, biodiversity and distribution, ecology and epidemiology, population biology and host-parasite relationships. The impact of parasites on the health and conservation of wildlife is seen as an important area covered by the journal especially the potential role of environmental factors, for example climate. Also important to the journal is ''one health'' and the nature of interactions between wildlife, people and domestic animals, including disease emergence and zoonoses.
