Carnivore parasites such as Hepatozoon spp., Babesia spp., Leishmania spp., Trypanosoma cruzi,
and Spirocerca spp. affect both domestic and wild carnivores, and some of them are zoonotic. In Chile,
there is limited or null information about their presence, although these parasites have been reported in
neighboring countries. The aim of our work was to determine its presence and importance for dogs and
wild foxes. Blood from 1139 dogs, 131 culpeo foxes (Lycalopex culpaeus) and 79 chilla foxes (L. griseus)
were obtained in six bioclimatic regions of Chile, and necropsies of 66 roadkill foxes were performed. The
presence of Hepatozoon spp. was found in 0.5% of dogs and 59% of foxes. Babesia vogeli was confirmed
in three dogs (4%) and in no fox. Leishmania spp., DNA was found in 4% of dogs and 5% of
foxes Trypanosoma cruzi in 17% and 10%, respectively. At necropsy, two foxes were found parasitized
with a Spirocerca sp. showing only about 94% identity with S. lupi. This study confirmed for the first time
the presence of Hepatozoon, Babesia, Leishmania, Trypanosoma and Spirocerca in dogs and/or foxes
from Chile. At the light of the results, risk factors analysis for these pathogens will provide tools for better
understanding the dynamic of parasitization in carnivores. These parasites should be taking into account
by Chilean veterinarians, physicians and wildlife managers.
