Resumen
Los estudios sobre las parasitosis de cánidos y en particular de Chrysocyon brachyurus Illiger,
1815 son escasos y existen pocos registros en el norte argentino. El objetivo del presente estudio
fue ampliar el conocimiento acerca de los helmintos parásitos de C. brachyurus. Se llevaron a
cabo las necropsias de dos ejemplares adultos de C. brachyurus de dos áreas protegidas de
Corrientes (Argentina). El material biológico consistió en vísceras de un macho proveniente del
Parque Nacional Mburucuyá y de una hembra de la Reserva Provincial Rincón de Santa María. A
partir de la necropsia del ejemplar proveniente del Parque Nacional Mburucuyá, se hallaron
helmintos localizados en el intestino (Centrorhynchus guira Lunaschi & Drago, 2010 y
Ancylostoma caninum Ercolani, 1859) y en el riñón derecho (Dioctophyme renale Goeze, 1782).
El ejemplar proveniente de la Reserva Rincón de Santa María presentó únicamente
Mesocestoides sp. Vaillant, 1863, localizado en el intestino delgado. Se registra por primera vez
las asociaciones C. guira – C. brachyurus y Mesocestoides sp. – C. brachyurus.
Canine parasitosis studies, in particular those of Chrysocyon brachyurus Illiger, 1815, are limited. Additionally, there are only few reports in the north of Argentina. The purpose of this study was to expand the knowledge about the helmith parasites of C. brachyurus. Necropsies of two adult specimens of C. brachyurus from two protected areas of Corrientes Argentina, were done in our laboratory. The biological material consisted of the viscera taken from a male canine found in the Mburucuya National Park and from a female found in the Rincon de Santa Maria Reserve. Centrorhynchus guira Lunaschi & Drago, 2010 and Ancylostoma caninum Ercolani, 1859 helminthes were found in the intestine, and Doctophyme renale Goeze, 1782 was found in the right kidney of the specimen coming from the Mburucuyá National Park. On the other hand, the specimen coming from the Rincon Santa Maria Reserve only presented with Mesocestoides sp Vaillant, 1863, in the small intestine. We here report for the first time, associations between C. guira - C. brachyurus and Mesocestoides sp. – C. brachyurus.
