Abstract

Kamegainema cingula (Linstow, 1902) (Nematoda: Dracunculidae) parasitizes subcutis of cryptobranchid salamanders in Japan and the U.S.A. Kamegainema is a monotypic genus including only K. cingula. Here, we analyzed the phylogenetic relationship of K. cingula in other dracunculid and micropleurid species. We also reported the seasonal change of the present species in the infection rate in the skin of Andrias species in Kyoto and Hyogo prefectures, Japan. We collected this species from the skin of Andrias japonicus and hybrids (A. japonicus × Andrias davidianus) from spring to early summer. Female K. cingula likely mature and release larvae during this season in Japan. In addition, K. cingula formed a sister clade to Micropleura as well as Dracunculus in our phylogenetic analysis.

日本大鲵寄生Kamegainema cingula（线虫纲：龙线虫科）的季节变化及系统发育地位

Kamegainema cingula (Linstow, 1902)（线虫纲：龙线虫科）寄生于日本和美国隐鳃蝾螈的皮下，Kamegainema是一个单型属，仅包括K. cingula。在此基础上，我们分析了金缕兰与其他龙尾科和微胸膜科物种的系统发育关系。我们还报道了本种在日本京都和兵库县的皮肤感染率的季节变化。本种采集于春季至初夏期间，采集于日本褐家蝇及其杂交品种（A. japonicus × Andrias davidianus）的皮肤。在这个季节，日本的雌性环带库蚊很可能成熟并释放幼虫。此外，在我们的系统发育分析中，K. cingula与Micropleura和Dracunculus形成了一个姐妹分支。

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.
