Spheniscidae na costa do Estado do Rio de Janeiro. Penguins are considered sentinels of the oceans, thus studies of these birds provide knowledge of the source and intensity of human impacts over marine habitats in the southern contracaeccum Boersma Anisakidae infection in Magellanic penguins Sphenisciformes: Ascaroidea in a steller sea lion and a white pelican.

A pink to bluish-pink hyaline material was formed deep in the gastric glands around the parasites. However, the intensity of parasitic infection was macroscopically rated as low.

In the present spp the cause of death was not fully elucidated. Determination of s number of parasites has not been carried out. Co-infections with Contracaecum pelagicum and C. Among the three animals infected by C. However, these birds become debilitated and malnourished, and often have infectious or non-infectious diseases, which interfere in the rehabilitation process Serafini et al.
