SUMMARY:

Recent years have shown the importance of zoonotic diseases for contemporary society. The world experienced an unprecedented pandemic for this generation, raising the alarm not only for neglected diseases, but for zoonoses as a whole. Some relevant zoonoses are hemoparasites that affect domestic and wild animals and, occasionally, humans. With the approach of humans to forest areas, deforestation, climate change, and other intrinsic and extrinsic factors, diseases that were previously only shared by animals, come to affect the health of different populations around the world. Thus, associating environmental, animal and human health, we arrive at the concept of One Health, through this very important triad. With this theme in mind, the present work studied a relevant area of the Atlantic Forest, the Serra dos Órgãos region, in the State of Rio de Janeiro. The region has an extensive green area, exuberant biodiversity and Conservation Units (UCs) that protect its area. Thus, this study aimed to investigate hemoparasites in fleas and ticks of domestic and wild animals and in the blood of domestic dogs. The Serra dos Órgão National Park (PARNASO) and its surrounding area, which covers the municipalities of Teresópolis, Petrópolis, Guapimirim and Magé, were chosen. All these municipalities have an area of Atlantic Forest protected by the park and urbanization areas close to the forests. This proximity to the urban and wild environment is a critical point when talking about conservation and public health. In partnership with PARNASO, ectoparasites were collected from wild animals run over on the roads that cut through the park. In order to bring more relevant information to the work, ticks collected from wild animals from the Center for Rehabilitation of Wild Animals (CRAS) in Rio de Janeiro, which are also animals belonging to the Atlantic Forest biome, were used. In all, ticks belonging to the species were found: Amblyomma aureolatum (29), with 3 samples of crab-eating fox being positive for Anaplasma spp. And 1 for Borrelia spp. Among the positive samples for Anaplasma spp., 1 was also positive for Rickettsia spp.; Amblyomma calcaratum (6) in sea urchins, where 2 samples amplified, 1 for Rickettsia spp. And 1 for Anaplasma spp.; Amblyomma dubitatum (3), in capybaras (2) and maned wolf (1) and PCR 1 of the capybara samples amplified for Rickettsia spp.; Amblyomma longirostre (8), in hedgehogs, where 1 amplified for Rickettsia spp and 1 for Anaplasma spp. Amblyomma nodosum (41), in anteaters, where they amplified 2 samples for Anaplasma spp; Amblyomma ovale (15), in 4 different host species, Irara, Mão-pelada, Cachorro-do-mato and Domestic dog. Of the 15 samples, where, among them, hemoparasites were found in 7 samples, Rickettsia spp (1), Anaplasma spp (4), Erlichia spp (3), Borrelia spp (1); Amblyomma rotundatum (1), in boa; Amblyomma sculptum (56), from crab-eating fox, domestic dog, capybara, caracara, opossum, maned wolf, raccoon, where only 5 samples amplified for Anaplasma spp.; Amblyomma sp (165), in crab-eating fox, squirrel, maned wolf, anteater and in PCR 27 samples were positive for Anaplasma spp and 2 for Borrelia spp.; Amblyomma varium (3), in laziness; Haemaphysalis juxtakochi (1), in tapiti; Ixodes schulzei (4) and Ixodes sp (1) in opossum. The blood collected from domestic animals did not test positive in PCR for any hemoparasitosis. It is pointed out that some molecular and serological tests will still be performed, in order to enrich the results and discussion. However, with the results processed so far, the presence of hemoparasites with zoonotic potential already mentioned in the literature is observed, highlighting the importance of understanding the health not only of the fauna of the region, but also of its environment and how this affects human health. Thus, the understanding of One Health discussed in this work aims to promote the health of local communities based on the identification of blood parasitic pathogens and their impact in a holistic way.
