First report of the digenetic trematode Psilochasmus oxyurus (Creplin) in the domestic goose, Anser anser (Linnaeus) in South America

Abstract

The digenetic trematode Psilochasmus oxyurus (Creplin, 1835) Lühe, 1909, although with a large geographical distribution, is referred in geese (Anser anser Linnaeus, 1758) for the first time in South America, on the basis of specimens parasitizing Brazilian domestic geese, with a prevalence of 20%. Brief morphometric data on the parasites are included. Clinical signs, gross and microscopic lesions were not observed in the birds.
