Abstract : 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.
