immunity status of blood donors regarding toxoplasma gondii infection in a low-income district of abidjan, côte d’ivoire, west africa

Background. Toxoplasmosis is a widespread cosmopolitan anthropozoonosis, which affects more than a third of the world population. Except the modes of transmission well known, Toxoplasma gondii can be transmitted during transplantation or blood transfusion. The aim of this study is to determine the prevalence of IgG and IgM Toxoplasma gondii and to estimate the potential risk by blood products. Methods. This is a cross-sectional study on the research for Toxoplasma gondii antibodies (IgG and IgM) blood donors performed by ELISA. Results. An overall seroprevalence of Toxoplasma gondii among blood donors recruited was 67.92% (n=72). Among these, 68 have Toxoplasma gondii IgG (64.15%), 12 Toxoplasma gondii IgM (11.32%), and 4 (3.77%) both. The risk varies between 8 for 100000 and 172 for 100000 donations. Conclusion. The need to strengthen security measures for people multitransfused, immunocompromised, and pregnant women to reduce the transmission of toxoplasmosis is important.
