Seroprevalence of Toxoplasma gondii in domestic and wild animals from the Fernando de Noronha, Brazil.
Abstract: 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.

This research examines the prevalence of a parasite, Toxoplasma gondii, in various domestic and wild animals on the archipelago of Fernando de Noronha, Brazil. The findings indicate that this parasitic infection is quite common in the studied animal populations on this island.
Research Context
- Fernando de Noronha is an archipelago in Brazil with rich biodiversity, including both native and non-native or synanthropic animals, who are adapted to live near humans.
- Toxoplasma gondii is a protozoan parasite that can infect a wide range of animals, including humans. It’s known to cause a disease called toxoplasmosis, which can be severe in immune-deficient individuals or newborns.
- Seroprevalence refers to the level of a pathogen’s presence in a particular population as measured in blood serum.
Research Methodology
- From July 2007 to May 2010, scientists collected blood samples from 764 animals on the island. This group consisted of both domestic and wild animals.
- The blood samples were tested using two methods: the indirect fluorescence antibody test (IFAT) and the modified agglutination test (MAT). Both of these methods enable the detection of antibodies to T.gondii in the samples, implying an ongoing or previous infection.
Results
- Antibodies to T. gondii were found in a significant proportion of all tested species, with prevalence ranging from 3% in cattle to over 80% in chickens and goats.
- In birds, particularly cattle egrets, the seroprevalence was also notably high, reaching almost 80%.
Implications
- The results show a widespread infection with T. gondii among both the domestic and wild fauna of the Fernando de Noronha archipelago.
- This indicates a high level of endemicity, making this a significant concern for both human and animal health on the archipelago.
- Further research could focus on identifying the main sources and transmission routes of this parasite and on implementing effective control measures.
