Penguins as marine sentinels. The anterior end of adult worms consisted of three round lips Fig. The aim of this paper was to report the occurrence and pathological findings of Contracaecum pelagicum and C. From July to Septembereleven young specimens of Magellanic penguins were investigated, regardless of sex, for helminthes in the digestive tract. A mean width of 0.

The average size of the lips was 0. They have found no obvious evidence of damage by the helminthes in any of the alimentary tracts of the Megadyptes antipodes in New Zeland.
Some nematodes were clarified in acetic acid P. Although the penguins of this study did not have ulcers, a hemorrhagic area was observed in the stomach of one animal.

The digestive tract was opened and placed in Petri dishes containing a 0. Spheniscidae from Argentinean coasts. Other macroscopic lesions found were pulmonary congestion, hepato- and splenomegaly.

In the present study the cause of death was not fully elucidated. The ulcers were dark gray with their surfaces coated with mucus and their bases with a layer of necrotic tissue in which the heads of the contracaevum were buried. Histopathological findings demonstrated esophagitis with helminthes segments inserted in the epithelium, showing discrete mixed inflammatory infiltrate of heterophils and mononuclear cells. Spheniscidae has a pelagic and predatory habit, migrating from its reproductive colonies, through ocean currents, to the Brazilian continental shore to eat.
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, conrracaecum they are rescued.
For a correct classification of the species, at ckntracaecum ten male and ten female parasites were observed and measured. Received on December 2, Anisakidae in Spheniscus magellanicus Aves: All of penguins were submitted to post-mortem examination.

However, the intensity of parasitic infection was macroscopically rated as low. In female, the uterus was sinuous with subglobular thick-shelled eggs.
These parasites may be associated with other diseases, implicating in death of the penguins. In that case, the parasite observed was Contracaecum spiculigerum.
