摘要

琉球长毛鼠，长毛鼠（啮齿目：鼠科），是一种濒临灭绝的物种，是日本西南岛屿的一部分——德岛、奄美大岛和冲绳岛的特有物种。在对福岛野生死亡个体的病理检查中，发现广州管圆线虫（线虫：管圆线虫科）、粗棘毛线虫（线虫：毛线虫科）和带绦虫（绦虫科）3种非本地寄生虫的淋巴瘤和感染。其中，广东棘球绦虫为人畜共患种，以入侵大鼠为最终宿主，软体动物为中间宿主。尽管在日本西南部岛屿上广泛报道了广东古猿的存在，但这是该物种在德野岛的首次记录。通过本研究，现已在发现该物种的所有三个岛屿的种群中证实了野生长尾田鼠的广州蠓感染。

First record of Angiostrongylus cantonensis infection in Diplothrix legata (Rodentia: Muridae) in Tokunoshima Island, Japan

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.
