Fernando de Noronha is an archipelago of 21 islands and islets in the Atlantic Ocean, state of Pernambuco, Brazil, which has a varied biodiversity including alien species or sinantropic animals. The objective here was to determine the seroprevalence of Toxoplasma gondii in domestic and wild animals from Fernando de Noronha archipelago, Brazil. Between July 2007 and May 2010, blood samples were collected from 764 animals (533 domestic and 231 wild animals). Sera were tested by the indirect fluorescence antibody test (IFAT) or the modified agglutination test (MAT), or by both. Antibodies to T. gondii were found in 80 (80.0%) of 100 chickens (Gallus domesticus), 3 (3.0%) of 100 cattle (Bos taurus), 59 (60.8%) of 97 sheep (Ovis aries), 9 (81.8%) of 11 goats (Capra hircus), 7 (43.7%) of 16 horses (Equus caballus), 70 (59.3%) of 118 cats (Felis catus), 36 (39.6%) of 91 dogs (Canis familiaris), 13 (38.2%) of 34 black rats (Rattus rattus), and 157 (79.7%) of 197 cattle egrets (Bubulcus ibis). Results indicate endemic infection by this zoonotic parasite among the animal and avian fauna in this archipelago from Brazil.
