  • Descrição: Background A survey of malaria antibodies was carried out over 7 years and a total of 777 serum samples from wild monkeys were collected in three distinct ecological areas of Brazil where autochthonous malaria has been reported: the Cerrado (similar to savanna), the Atlantic Forest and the Atlantic Semideciduous Forest.Methods We carried out enzyme-linked immunosorbent assay to investigate the presence of IgG antibodies against peptides of the circumsporozoite protein (CSP) repeat region of classic Plasmodium vivax, P. vivax VK247, human P. vivax-like P. simiovale, P. brasilianum P. malariae and P. falciparum. We also carried out immunofluorescence assay with asexual forms of P. vivax, P. malariae and P. falciparum. Results The high prevalence of antibodies against CSP in all areas indicates that the monkeys had intense contact with sporozoites from infected anophelines. The immune response against asexual forms of Plasmodium in the monkeys from the Atlantic Forest indicates the development of the infection.Conclusions We discuss the possibility of monkeys being malaria reservoirs in non-endemic areas
