10 out. PDF | This work describes the presence of Contracaecum sp. larvae (Nematoda: Anisakidae) found in food fish of economic importance. Contracaecum genus (Ascaridida: Anisakidae) is a nematode parasite of the fish- eating birds throughout the world. A heavy infection of Contracaecum sp. was. Birds are frequently mentioned as hosts of Contracaecum sp. One cormorant species, Phalacrocorax brasilianus (syn olivaceus) Gmelin, (TORRES, ;.

Anisakidae have several species of fish as intermediate or paratenic hosts, and piscivorous birds and mammals contracaecu definitive hosts Anderson Spheniscidae from Argentinean coasts. Contracaecum magnipapillatum Nematoda, Ascaridoidea: InTimi et al. These parasites may be associated with other diseases, implicating in death of the penguins.
Contracaecum sp | Parasites World
Anisakidae in Spheniscus magellanicus Aves: In male worms, the elongated spicules were equal and the conical tail curved ventrally Fig. The average size of the lips for males and females was 0. Five-micrometer sections were stained with hematoxylin and eosin HE.
Mortality in little penguins Eudyptula minor along the coast of Victoria, Australia. Spheniscidae were reported on the coast of Rio de Janeiro. Spheniscidae has a pelagic and predatory habit, migrating from its reproductive colonies, through ocean currents, to the Brazilian continental shore to eat. Helminth and protozoan parasites of the alimentary tract of the yellow-eyed penguin Megadyptes antipodes.
Contracaecum pelagicum and C. 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.

The anterior end of adult worms consisted of three round lips Fig. All contraczecum penguins were submitted to post-mortem examination. Contracaecum pelagicum was described infecting penguins from the species S. The occurrence of infections and the disease induced by Contracaecum plagiaticium and Contracaecum pelagicum in Magellanic penguins, Spheniscus magellanicus Foster. Gastrointestinal helminthes of fish-eating birds from Valdivia River, Chile.
Zoo and Aquarium Assoc. Parasites of the genus Contracaecum were present in all of the 11 studied animals. In female, the uterus was sinuous with subglobular thick-shelled eggs.
However, these birds become debilitated and malnourished, and often have infectious or non-infectious diseases, which interfere in the rehabilitation process Serafini et al. However, the intensity of parasitic infection was macroscopically rated as low. The average size of contracaecmu lips was 0. Gastrointestinal parasitosis is a common hygienic-sanitary problem in captive animals, being one of the most important disorders that contribute to the weakening of these birds Fonseca et al.
Resurrection and pathogenic effects of a common parasite from the proventriculus of Anous minutus from the Great Barrier Reef, with a note on C. One of these animals 9. One bird was parasitized by C. 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.
For Contracaecum pelagicumin the present study, the mean body length was Services on Demand Journal. How to cite this article.
However, parasite diversity studies in this bird are scarce and the presence of C. Gastric ulcers associated with Contracaecum spp. In the present study, the underweightness and the palpable keel-shaped sternum observed were probably due to food privation Rupley From July to Septembereleven young specimens of Magellanic penguins were investigated, regardless of sex, for helminthes in the digestive tract. It is believed that infection has occurred due to piscivorous feeding habits during the pelagic time of S.
Gross lesions in animals infected by Contracaecum spp. The average s was 0. In Brazil, recent reports of parasitism by C. However, these findings are unspecific and thus impossible to be related to gastrointestinal parasitism. Several factors play a role in the weakening and high mortality rates of Magellanic penguins during the northward migration.
