Principles of disease prevention: It is believed that infection has occurred due to piscivorous feeding habits during the pelagic time of S. The formation of the hyaline material around the nematodes in the stomach glands was not fully understood.

Helminth and protozoan parasites of the alimentary tract of the yellow-eyed penguin Megadyptes antipodes. In the present study, six animals The body showed a thick cuticle bearing transverse striations Fig.
Secondary bacterial invasion and subsequent heterophil infiltration of the adjacent tissues were also noted in cross-sections of these two penguins. They have found no obvious evidence of damage by the helminthes in any of the alimentary tracts of the Megadyptes antipodes in New Zeland. A pink to bluish-pink hyaline material was formed deep in contracaecuj gastric glands around the parasites. The anterior end of adult worms consisted of three round lips Fig.

However, these findings are unspecific and thus impossible to be related to gastrointestinal parasitism. Contracaecum pelagicum was described infecting penguins from the species S. Iowa State University Press, Ames.
Spheniscidae on the coast of Rio de Janeiro State. However, it was possible to conclude that Magellanic penguins are susceptible to gastrointestinal parasites and that at least two different species of the genus Contracaecum occur in birds captured on the coast of Rio de Janeiro State, thus they may be associated to other diseases, implicating in the death of these penguins. In the female worms, the distance between the anus and the posterior end was 0.
The average size of the lips for males and females was 0.
The aim of this paper was to report the occurrence and pathological findings of Contracaecum pelagicum and C. Mortality in little penguins Eudyptula minor along the coast of Victoria, Australia. Spheniscidae has a pelagic and predatory habit, migrating from its reproductive colonies, through ocean currents, to the Brazilian continental shore to eat.

Several factors play a role in the weakening and high mortality rates of Magellanic penguins during the northward migration. Histopathological findings demonstrated esophagitis with helminthes segments inserted in the epithelium, showing discrete mixed inflammatory infiltrate of heterophils and mononuclear cells. Determination of the number of parasites has not been carried out.
Further study of Contracaecum pelagicum Nematoda: Parasites of the genus Contracaecum Railliet et Henry, Nematoda: The average width was 0. One bird was parasitized by C. Penguins as marine sentinels. Spheniscidae from Contacaecum coasts. In the cases of parasitism by C.
