BONAMETTI, Ana M. et al. Trypanosoma cruzi infection in blood donors. Rev. Saúde Pública [online]. 1998, vol.32, n.6, pp.566-571. ISSN 1518-8787.

INTRODUCTION: Transmission of American trypanossomiasis by transfusion has been reduced by expansion of control measures of blood quality in Brazil. A research project was, therefore, undertaken to evaluate soropositivity for Trypanosoma cruzi infection on blood donors and to compare this rate with those found in 1958 and 1975 in blood banks. METHOD: A transversal study was carried out on blood donors in Londrina, Paraná, Brazil. ELISA and Immunofluorescence were the serological test techniques used in the diagnosis of Trypanosoma cruzi infection. RESULTS AND CONCLUSION: A serumprevalence rate of 1.3% was found with a tendency for positive serum findings for Trypanosoma cruzi infection on blood donors to decrease over Aime (1958, 1975, and 1995).
