Rangelia vitalii in a free-ranging maned wolf (Chrysocyon brachyurus) and co-infections
نویسندگان
چکیده
An adult free-ranged female maned wolf was rescued from a periurban area subject to anthropogenic disturbances in the Minas Gerais, Brazil. The animal presented poor body condition and anemia. The clinical condition rapidly deteriorated culminating in dead and a necropsy was performed. The main gross lesions were marked anemia and blood content in the intestines accompanied by many types of parasites. The protozoa Rangelia vitalii was identified by histopathological analysis predominantly within the cytoplasm of endothelial cells of capillaries of the small intestine. The lymph nodes, spleen, bone marrow, dermis, lungs and kidney had similar protozoal forms but with mild or moderate intensity. Rangelia vitalii was confirmed by molecular assays. Hepatozoon sp., Leishmania sp., and Entamoeba spp., apparently not related to the clinical signs were also detected. The myriad parasites found in the intestines included nematodes (Ancylostoma caninum, A. braziliensis,, Molineus sp., Pterygodermatites sp., and Trichuris sp.), cestodes (Spirometra sp.) and (acanthocephalans. To our knowledge, R. vitalii was identified in C. brachyurus for the first time. These findings emphasize the fragility of Brazilian ecosystems, especially in disturbed areas, reinforcing the necessity of efforts to preserve these areas and wild carnivores, some of which are threatened with extinction, such as the maned wolf.

Myiasis by screw worm Cochliomyia hominivorax (Coquerel) (Diptera: Calliphoridae) in a wild maned wolf Chrysocyon brachyurus (Mammalia: Canidae), in Brasília, Brazil.
In April 2009, a wild maned wolf, Chrysocyon brachyurus, was captured in an area of cerrado in Brasília, DF, Brazil, with screw worm maggots in external wounds. Fifty larvae were bred in the laboratory and eight adults of Cochliomyia hominivorax (Coquerel) emerged 10 days after pupation. This is the first report of a myiasis by C. hominivorax in a free-living maned wolf in Brazil.

The entodiniomorph ciliates (Ciliophora: Entodiniomorphida) are endosymbiotes widely found in the intestines of herbivorous mammals. These commensals commonly occur in the Artiodactyla and Perissodactyla and have also been described in the Proboscidea, Primates, Rodentia, and Diprotodontia. This study reports the first finding of a ciliate in a member of order Carnivora, the maned wolf (Chrysoc...
