SUMMARY:

Fernando de Noronha Archipelago has a high biodiversity related to bird species. Besides, Fernando de Noronha hosts invasive species, as the domestic cat (Felis catus). Cat presence represents a high risk to bird species, as well as for humans due to transmission of zoonotic diseases. These risks are related to birds as well, once factors related to antropization can impact the survival of these species, and lead to zoonotic pathogens dissemination. Toxoplasmosis, neosporosis, feline immunodeficiency vírus (FIV), feline leukemia vírus (FeLV), west nile fever (WNF), newcastle disease (ND), and avian influenza (AI) had become even more frequent. It is extremely important to realize epidemiologic investigation on all these infections. The objective of this study was to realize molecular research of FNO, DN, and IA vírus on wild birds; anti-T. gondii and anti-Neospora caninum antibodies occurrence, as well as isolation and biological characterization of the T. gondii, and molecular research for FIV and FeLV on cats of Fernando de Noronha Archipelago. 225 animals’ sample were obtained on total, being 125 from 11 species of wild birds: 62 noronha vireo (Vireo gracilirostris), 52 noronha elaenia (Elaenia ridleyana), three white-tailed tropicbird (Phaeton lepturus), two eared dove (Zenaida auriculata), one brown booby (Sula leucogaster), one magnificent frigatebird (Fregata magnificens), one sooty tern (Onychoprion fuscatus), one red-footed booby (Sula sula), one black noddy (Anous minutus), and one brown noddy (Anous stolidus), and 100 from cats (81 stray cats and 19 feral cats). 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.
