Abstract：
Originally from Asia, the raccoon dog Nyctereutes procyonoides is an invasive alien species in Europe, listed since 2019 on the List of invasive alien species of Union concern. The raccoon dog is considered to have negative impact on native biodiversity, as well as a crucial role in hosting and transmitting diverse parasites and pathogens of human and veterinary importance. In the present study, stomach content analyses and parasitological examinations were performed on 73 raccoon dogs from Germany. In addition, fecal samples were analyzed. The results of the study confirm the assumption that the examined raccoon dogs were infested with a various ecto- and endoparasite fauna. A total of 9 ecto- and 11 endoparasites were detected, with 6 of the endoparasites having human pathogenic potential. Trichodectes canis (P = 53.42%), Toxocara canis (P = 50.68%) and Uncinaria stenocephala (P = 68.49%) were the most abundant parasite species. The stomach contents consisted of approximately one-third vegetable and two-thirds animal components, composed of various species of amphibians, fish, insects, mammals and birds. Among them were specially protected or endangered species such as the grass frog Rana temporaria. The study shows that the raccoon dog exerts predation pressure on native species due to its omnivorous diet and, as a carrier of various parasites, poses a potential risk of infection to wild, domestic and farm animals and humans.
摘要：
最初来自亚洲，浣熊犬是欧洲的外来入侵物种，自2019年以来被列入联盟关注的外来入侵物种名单。浣熊狗被认为对本地生物多样性有负面影响，以及在托管和传播人类和兽医重要的各种寄生虫和病原体方面的关键作用。在本研究中,对来自德国的73只浣熊犬进行了胃内容物分析和寄生虫学检查。此外,分析粪便样本。研究结果证实了以下假设：所检查的浣熊犬感染了各种外来和内寄生虫动物。共检测到9个体外寄生虫和11个体内寄生虫，其中6种具有人类致病潜力的内寄生虫。犬毛织物(P=53.42%),犬弓形虫（P=50.68％）和钩虫（P=68.49％）是最丰富的寄生虫。胃内容物由大约三分之一的蔬菜和三分之二的动物成分组成，由各种两栖动物组成，鱼,昆虫,哺乳动物和鸟类其中有特殊保护或濒危物种，例如草蛙Ranatemporaria。研究表明，浣熊犬由于其杂食性饮食而对本地物种施加捕食压力，作为各种寄生虫的载体，有感染野生生物的潜在风险,家畜和农场动物和人类。
