Baylisascaris procyonis is a zoonotic nematode whose main definitive host is the raccoon, an invasive carnivore in Europe introduced from the United States. B. procyonis causes larva migrans with poor prognosis in humans. This parasite was unexpectedly detected in France for the first time upon molecular screening of wolf faecal samples. Because no patent infection was found, the wolf cannot be considered as a definitive host. This discovery of B. procyonis in France nonetheless raises questions about the parasite status of the expanding raccoon populations in the country, which will be investigated in the future.

从法国狼中的人畜共患的round虫Baylisascaris procyonis中检测DNA。

Baylisascaris procyonis是一种人畜共患线虫，其主要寄主是浣熊，这是一种从美国引进的欧洲侵入性食肉动物。B. procyonis导致幼虫移行，人类预后不良。在对狼粪样进行分子筛查后，法国首次意外地发现了这种寄生虫。由于未发现专利感染，因此不能将狼视为确定的宿主。尽管如此，在法国的procyonis B. procyonis的发现仍然引起了人们对该国不断增长的浣熊种群寄生虫状况的质疑，并将在以后进行调查。
