Penguins as marine sentinels. Co-infections by Csontracaecum pelagicum and C. The average width was 0. For Contracaecum pelagicumin the present study, the mean body length was The formation of the hyaline material around the nematodes in the stomach glands was not fully understood.

Accepted for publication on August 3, Micrographs of some morphological characteristics were obtained with an Olympus BX bright field microscope. Gross lesions in animals infected by Contracaecum spp. From July to Septembereleven young specimens of Magellanic penguins were investigated, regardless of sex, for helminthes in the digestive tract. However, the intensity of parasitic infection was macroscopically rated as low.

For a correct classification of contracaevum species, at least ten male and ten female parasites were observed and measured. A pink to bluish-pink hyaline material was formed deep in the gastric glands around the parasites. Spheniscidae were reported on the coast of Rio de Janeiro.
