SUMMARY:

Fernando de Noronha Archipelago has a high biodiversity in terms of bird species, in addition to being home to species with invasive potential, such as the domestic cat (Felis catus). The presence of cats represents a great risk for bird species, as well as for the human population, due to the transmission of zoonotic diseases. These same risks occur with birds, since factors intrinsically linked to anthropogenic activity can impact their survival, also leading to the spread of zoonotic pathogens in these populations. Pathogens causing toxoplasmosis, neosporosis, Feline Immunodeficiency (FIV), Feline Viral Leukemia (FeLV), West Nile Fever (WNF), Newcastle Disease (ND) and Avian Influenza (AI) have become increasingly frequent, being of It is extremely important to carry out epidemiological investigations. In this context, the objective was to verify the occurrence of anti-T. gondii and anti-Neospora caninum, carry out the isolation and biological characterization of Toxoplasma gondii, and molecular research on FIV and FeLV viruses in cats and carry out molecular research on WNF, ND and AI viruses in wild birds of the Fernando de Noronha Archipelago. In total, samples were obtained from 229 animals, including 100 cats (n=100, 19 feral and 81 domestic) and 129 wild birds of 12 species (62 Noronha vireo Vireo gracilirostris, 52 Noronha elaenia Elaenia ridleyana, 3 sparrows Passer domesticus, 2 eared dove Zenaida auriculata, 1 brown booby Sula leucogaster, 1 magnificent frigatebird Fregata magnificens, 1 sooty tern Onychoprion fuscatus, 1 red-footed booby Sula sula, 1 white-tailed tropicbird Phaeton lepturus, 1 black noddy Anous minutus, 1 brown noddy Anous stolidus and 1 cattle-egret Bulbucus ibis. Among the 100 cat blood serum samples analyzed, 30 (30%) were positive for anti-T. gondii. Regarding the other pathogens studied, all agent isolation and molecular diagnoses in cats and birds were negative. Even with the negative results, of great importance especially in Avian Influenza in wild birds and poultry production, it is necessary to continue monitoring the risks of transmission of these pathogens. Therefore, it is essential to maintain this research, aiming to assist Health and Environment managers in implementing public policies to promote One Health
