The formation of the hyaline material around the nematodes in the stomach glands was not fully understood. Histopathological findings demonstrated esophagitis with helminthes segments inserted in the epithelium, showing discrete mixed inflammatory infiltrate of heterophils and mononuclear cells.

Further study of Contracaecum pelagicum Nematoda: The necropsies were performed using the technique previously described by Zander et al. Penguins are considered sentinels of the oceans, thus contracaecuk of these birds provide knowledge of the source and intensity of human impacts over marine habitats in the southern hemisphere Boersma Spheniscidae on the coast of Rio de Janeiro State.
In this route, some specimens may deviate from the group, reaching more distant areas of the Brazilian coast, like Rio de Janeiro State and others beaches, where they are rescued. Engrauliidae from the Argentine and Uruguayan Seas. However, these findings are unspecific and thus impossible to be related to gastrointestinal parasitism.
