The occurrence of infections and the disease induced by Contracaecum plagiaticium and Contracaecum pelagicum in Magellanic penguins, Spheniscus magellanicus Foster. 1781 (Sphenisciformes: Spheniscidae) were reported on the coast of Rio de Janeiro. Parasites of the genus Contracaecum were present in all of the 11 studied animals. Co-infections by Csontracaecum pelagicum and C. plagiaticium were observed in three hosts (27.27%). Gross lesions included hyperemia of the esophagus and/or stomach in six animals (54.54%). One of these animals (9.09%), parasitized by C. plagiaticium, presented a hemorrhagic area in the gastric mucosa. Histopathological findings demonstrated esophagitis with helminthes segments inserted in the epithelium, showing discrete mixed inflammatory infiltrate of heterophils and mononuclear cells. These parasites may be associated with other diseases, implicating in death of the penguins.
