Until recently, Angiostrongylus vasorum was not considered to be an endogenous Danish parasite, since demonstration of this worm had been confined to necropsy findings in 2 dogs, both of which had visited France. During the last 2 years, however, clinical cases have been diagnosed among a considerable number of Danish dogs, none of which had ever been outside Denmark. All these cases have occurred north of Copenhagen, where an endemic focus seems to exist. In this field survey A. vasorum was found for the first time in wild Danish red foxes. Furthermore, experimental infections showed that the parasite can be transferred between foxes and dogs. Consequently, the wild fox population must be considered a potential reservoir for transfer of A. vasorum to domestic dogs.
直到最近，管圆线虫还未被视为丹麦本土寄生虫，因为此前仅在两只去过法国的犬尸检中发现过这种线虫。然而，在过去两年里，丹麦有相当数量的犬被诊断出患有临床病例，这些犬都未曾离开过丹麦。所有这些病例都发生在哥本哈根以北地区，这里似乎存在一个地方性疫源地。在此次实地调查中，首次在丹麦野生赤狐体内发现了管圆线虫。此外，实验感染表明该寄生虫可在狐狸和犬之间传播。因此，野生狐狸种群必须被视为管圆线虫向家犬传播的潜在宿主。
