The cardiopulmonary nematodes and , are a cause of concern in the scientific and veterinary community, potentially causing significant disease in domestic animals. To investigate the potential of wild carnivores as reservoir hosts to these parasites, a total of 1041 animals from seven regions of Denmark were sampled: 476 raccoon dogs (), 367 red foxes (), 123 American mink (), 31 beech martens (), 30 Eurasian otters () and 14 polecats (). Hearts and lungs were collected and examined for cardiopulmonary parasites. was identified using morphology, whereas and were identified by a duplex real-time PCR, and by conventional PCR. This is the first Danish report of and infections in raccoon dogs, mink and polecats, and of in raccoon dogs and beech martens. In addition, this is the first time and have been identified in wild animals from the island of Bornholm, just as it is the first report of in American mink, and and in polecats in Europe. The prevalence of appears to have increased in red foxes in Denmark compared to previous studies, while and prevalences are lower. Our data show that several wild carnivores can serve as reservoir hosts for and in Denmark, and that appears more abundant than previously reported. It is speculated that the increase might relate to increased snail abundance, which may be due to a rise in mean yearly temperatures in Denmark.
心肺线虫 和 是科学界和兽医界关注的对象，可能会在家畜中引发严重疾病。为了调查野生食肉动物作为这些寄生虫储存宿主的可能性，从丹麦七个地区共采集了1041只动物样本：476只貉、367只赤狐、123只美洲水貂、31只石貂、30只欧亚水獭和14只艾鼬。采集心脏和肺脏并检查其中的心肺寄生虫。通过形态学鉴定 ，而 和 通过双重实时PCR鉴定， 通过常规PCR鉴定。这是丹麦首次报道貉、水貂和艾鼬感染 和 ，以及貉和石貂感染 。此外，这是首次在博恩霍尔姆岛的野生动物中鉴定出 和 ，也是欧洲首次报道美洲水貂感染 以及艾鼬感染 和 。与之前的研究相比，丹麦赤狐中 的感染率似乎有所上升，而 和 的感染率较低。我们的数据表明，在丹麦，几种野生食肉动物可以作为 和 的储存宿主，而且 似乎比之前报道的更为常见。据推测， 的增加可能与蜗牛数量的增加有关，这可能是由于丹麦年平均气温上升所致。
