Seroprevalence of Toxoplasma gondii in Domestic and Wild Animals From the Fernando de Noronha, Brazil

A comprehensive study on the Brazilian Atlantic Island of Fernando de Noronha revealed a widespread endemic infection of Toxoplasma gondii among both domestic and wild animals, with seroprevalence rates ranging from 3% to 81.8% across various species. The research, conducted between 2007 and 2010, analyzed blood samples from 764 animals, including chickens (80%), cattle (3%), sheep (60.8%), goats (81.8%), horses (43.7%), cats (59.3%), dogs (39.6%), black rats (38.2%), and cattle egrets (79.7%). The findings highlight the archipelago's role as a significant reservoir for this zoonotic parasite, posing potential risks to both local wildlife and human health.
