Capybara (Hydrochaeris hydrochaeris) is a rodent of half-aquatic habits, herbivores, exploring aquatic gradients where other herbivores normally don t reach, mainly in flooding areas, being distributed for all the Brazilian territory. Its natural habitat is characterized by the permanent existence of watercourse, and they also require an area of pasture to explore and an area of bush used for rest and to have younglings. Although being a wild animal, it in a so advanced way in the domestication process that can be considered as a new domestic animal, with well established handling and use. Capybaras are regularly kept in close contact with swine, equines and bovines, leading to a bigger dispersion of illnesses, with capybaras being able to act as reservoir, doing important paper in public health and the economic losses in production animals and commercial breeding of the species. Identification stories of some infectious agents in free-life capybaras, as much in wild as in agricultural areas, contribute to this hypothesis. On this way this work had the objective of analyzing the serologic profile of capybaras, as soon as the presence of antibodies against bovine Herpesvirus, bovis Viruses of bovine leukemia, Viruses of equine influenza, Rickettsia, Anaplasma marginale, Babesia bovis, Babesia bigemina, brucellas and leptospires. Blood samples of capybaras from different region had been collected. These samples had been processed in the laboratory of Virology of the Sector of Preventive Veterinary Medicine of the Universities Federal de Viçosa, being submitted to the tests of immuno-diffusion in agar-gel for the virus of bovine leukemia, serum-neutralization for bovine herpes virus, inhibition of the hemaglutination for the virus of equine influenza, indirect immunofluorescence for Rickettsia, elisa for Anaplasma marginale, dot-elisa for Babesia bovis and bigemina Babesia, fast serum agglutination for brucellas and microscopically serum aglutination for Leptospires (15 different sorovares). Gotten results (18/144) indicate the prevalence of antibodies against leptospires of 10,42% (15/144) and 2,09% (3/144) against the equine influenza virus. Antibodies for the other tested agents had not been found. There is great evidence that the creation of capybaras has an important paper in the epidemiologist of the infection for Leptospires, serving as reservoir and potential disseminator for the environment. However, there is a necessity of a more refined evaluation, related to the sanitary and economic aspects to other diseases occurring in capybaras, as well as a deeper relation with other production animals.
