The occurrence of ectoparasites in wild nutria is poorly understood. Fifty-five livetrapped wild nutria (Myocastor coypus) from its indigenous region were examined for ectoparasites after capture from December 2013 to December 2014. The captures came from the Buenos Aires Province, by far the area of the country most densely populated by nutria, characterized as a temperate grassland, which are prime areas for sustained agriculture. Only one species of chewing lice (Pitrufquenia coypus, Marelli, 1932), one flea (Nosopsyllus fasciatus, Bosc, 1800) and one tick (Rhipicephalus sanguineus, Latreille, 1806) were collected. Fourteen percent of the animals were infested and P.coypus, an obligate parasite of the nutria, which was the most prevalent ectoparasite. N. fasciatus and R. sanguineus occurrence remains controversial as they may or may not be some accidental host species. To our knowledge, this is the first comprehensive and systematic survey of ectoparasites in wild nutria from the southern hemisphere, the indigenous region of this species.
人们对野生海狸鼠体外寄生虫的发生情况了解甚少。2013年12月至2014年12月期间，从其原生地区捕获了55只野生海狸鼠（Myocastor coypus），并在捕获后对其进行了体外寄生虫检查。捕获地点来自布宜诺斯艾利斯省，该省是该国海狸鼠种群最为密集的地区，属于温带草原，是持续农业的主要区域。仅采集到一种嚼虱（Pitrufquenia coypus，Marelli，1932年）、一种跳蚤（Nosopsyllus fasciatus，Bosc，1800年）和一种蜱虫（Rhipicephalus sanguineus，Latreille，1806年）。14%的动物受到感染，其中海狸鼠专性寄生虫P.coypus是最常见的体外寄生虫。N. fasciatus和R. sanguineus的出现仍存在争议，因为它们可能是也可能不是偶然的宿主物种。据我们所知，这是对来自南半球该物种原生地区的野生海狸鼠体外寄生虫进行的首次全面系统调查。
