prevalence and level of antibodies to the circumsporozoite protein of human malaria parasites in five states of the amazon region of brazil.the aim of this study was to determine the prevalence of malaria infection and antibodies against the repetitive epitopes of the circumsporozoite (cs) proteins of plasmodium falciparum, p. malariae, p. vivax vk210, p. vivax vk247, and p. vivax-like in individuals living in the states of rondônia, pará, mato grosso, amazonas, and acre. active malaria transmission was occurring in all studied sites, except in acre. p. falciparum was the predominant species in pará and rondônia and p. vivax in mato ...200717568943
high prevalence of plamodium malariae infections in a brazilian amazon endemic area (apiacás-mato grosso state) as detected by polymerase chain reaction.plasmodium malariae is commonly confounded with plasmodium vivax at the microscopic examination of thick blood smear. in the present study, we used a nested pcr assay to amplify a species-specific sequence of the 18s ssu rrna gene of plasmodium in blood samples of 497 individuals living in an endemic region of the brazilian amazon basin. we have found that, while the microscopic examination of thick blood smears showed a p. malariae prevalence of 1.2% (6 out of 497), the nested pcr revealed 11.9 ...200414739024
