Diversity of endohelminths parasitizing bred Muscovy ducks (Anseriformes: Anatidae) from the eastern Brazilian Amazon.

Raising of Muscovy ducks for subsistence of human populations is common in northern Brazil, although their helminth infections have been poorly investigated, despite the possible presence of helminths with zoonotic potential. The aim of this study was to investigate the diversity of parasite endohelminths in raised in the Marajó Island region, state of Pará, Brazilian Amazon region. Of 33 specimens examined, 90.9% were parasitized by one or more parasite species, for a total of 926 parasites recorded. The species mean richness of endohelminths varied from 0 to 6, and there was a predominance of hosts with 1 to 2 species of parasite endohelminths and low prevalence and low abundance of parasites. This was the first report of larvae of sp., sp., sp., sp., sp., sp., sp. and for . The parasitic community of was composed of 11 species, with a high species richness for nematode species and a small number of digeneans.
