[Detection of intestinal parasites from main-land raccoon dogs, Nyctereutes procyonoides viverrinus, in southeastern Kanagawa Prefecture].
ABSTRACT To obtain the basic data on the route of infection of intestinal parasites as zoonosis, we examined the feces from 87 main-land raccoon dogs, all of which were kept in the Yokohama Kanazawa Zoo (Kanagawa) between 1994-1996, for detection of intestinal parasites and evaluated the detection rates. Intestinal parasites were detected from 72 of the 87 raccoon dogs (82.8%). Among the parasites, Ancylostoma spp., Trichuris vulpis, Ascaridoidea and Isospora spp. were most commonly detected. Of the 72 raccoon dogs with parasites, 43 (59.7%) had mixed infection of more than two species of parasites. Since Ancylostoma spp., Ascaridoidea and Isospora spp., which are important causes of human diseases, were detected at relatively high rates, it was suggested that the raccoon dog could be a source of human infection of intestinal parasites.
