“…The species was first described from albatrosses from Australia and, since then the species was reported in South America from Thalassarche melanophris (=Diomedea melanophris (Temminck, 1828), the South American penguin, Spheniscus magellanicus (Forster, 1781), Spheniscus humboldti Meyen, 1834 and Sula leucogaster Boddaert, 1783 (LENT;FREITAS, 1948;SANTOS, 1984;MANN, 1992;SILVA et al, 2005;GARBIN et al, 2007;GONZÁLEZ-ACUÑA et al, 2008;EDERLI et al, 2009;DIAZ et al, 2010;PRADO et al, 2011;YÁÑEZ et al, 2012;REZENDE et al, 2013;CAMPOS et al, 2013).…”

Three new sequences of Mitochondrial cytochrome c-oxidase subunit 2 (mtDNA cox-2) from C. pelagicum parasite of Spheniscus magellanicus, the Magelanicus penguin, were determined from Brazilian waters. The sequences presented 99 and 98% of similarity with C. pelagicum sequences from Argentina, deposited on GenBank for the same genetic region and with a strong statistical support inferred from the phylogenetic tree. The morphological and ultrastructural studies that were carried out confirmed the genetic analysis.Keywords: Anisakidae, penguin, Rio de Janeiro. ResumoForam determinadas três novas sequências da região do Citocromo c-oxidase da subunidade II do DNA mitocondrial (cox-2 mtDNA) de Contracaecum pelagicum, parasito de Spheniscus magellanicus, pinguim Magalhães, de águas brasileiras. As sequências apresentaram 99 e 98% de similaridade com sequências de C. pelagicum da Argentina depositadas no GenBank da mesma região genética com forte suporte estatístico inferido pela arvore filogenética. Estudos morfológicos e ultraestruturais realizados confirmaram a identidade genética.

Introduced species can arrive into new territories with parasites; however, these species are expected to face lower parasite richness than in their original regions. Both introduced hosts and parasites can affect native fauna. Since their release into the wild in Chile following laboratory use, Xenopus laevis Daudin, 1802 has widely spread throughout central Chile. The only pathogen described on the host is the fungus Batrachochytrium dendrobatidis Longcore, Pessier, Nichols, 1999; thus, this is the first parasitological study of this species in Chile. In 10 localities in central Chile, 179 specimens of X. laevis were captured and examined for parasites in the gastrointestinal tube, cavities, lungs, liver, and skin. Only nine specimens of the genus Contracaecum Railliet, Henry, 1912 were found in six specimens of X. laevis from a private dam in La Patagua. It is likely that these parasites originated from species of native birds. This is the first record of Contracaecum sp. in Chilean amphibians.

“…The parasite C. rudolphii was described in Phalacrocorax olivaceus in Chile (Torres et al 1982(Torres et al , 1991 and in the same country S. magellanicus was observed parasitized by Contracaecum sp. and C. pelagicum in its stomach and intestines (Pazos et al 2003, González-Acuña et al 2008. C. pelagicum was also found in S. magellanicus in Argentina (Garbin et al 2007).…”

Parasitos do gênero Contracaecum estavam presentes em todos os 11 animais estudados. Co-infecção por Contracaecum pelagicum e C. plagiaticium foi observada em três hospedeiros (27,27%). Achados macroscópicos de necropsia incluíram hiperemia do esôfago e/ou estômago em seis animais (54,54%). Um desses animais (9,09%), parasitado por C. plagiaticium, apresentou área hemorrágica na mucosa gás-trica. Os achados histopatológicos demonstraram esofagite com segmento de helminto inserido no epitélio, e discreto infiltrado inflamatório misto com heterófilos e células mononucleares. Estes parasitos podem estar associados a doenças, implicando em morte dos pinguins.TERMOS DE INDEXAÇÃO: Pinguim-de-Magalhães, Contracaecum plagiaticium, Contracaecum pelagicum, patologia.

Parasites of the genus Contracaecum were present in all of the 11 studied animals. Co-infections by Csontracaecum pelagicum and C. plagiaticium were observed in three hosts (27.27%). Gross lesions included hyperemia of the esophagus and/or stomach in six animals (54.54%). One of these animals (9.09%), parasitized by C. plagiaticium, presented a hemorrhagic area in the gastric mucosa. Histopathological findings demonstrated esophagitis with helminthes segments inserted in the epithelium, showing discrete mixed inflammatory infiltrate of heterophils and mononuclear cells. These parasites may be associated with other diseases, implicating in death of the penguins.
