Objective: Since pre-transfusion screening for Toxoplasma gondii is not performed on blood packs, thalassemia patients are susceptible to acquiring toxoplasmosis; thus, the aim of this study was to evaluate the seroprevalence status of T. gondii in individuals who suffer from thalassemia in comparison to healthy persons in the southwest of Iran. Methods: In this case-control study, 117 thalassemia patients and 205 healthy persons participated. All samples were tested for the presence of specific IgG and IgM antibodies against T. gondii using ELISA technique. Data were analyzed using Chi-square test. >Results: Seroprevalence of anti-T. gondii IgG was detected in 30.76% (36/117) of patients and 20% (41/205) of healthy individuals (P=0.04), also anti-T. gondii IgM in these groups was detected 1.70% (2/117) and 0.48% (1/205), respectively (P=0.3). In present study, nine related risk factors with toxoplasmosis were evaluated and data analysis showed that only contact with cat was significantly correlated with IgG seroprevalence (P=0.02). >Conclusions: Current research suggests thalassemia patients are more prone than normal persons to acquiring T. gondii infection (P=0.04, OR:1.77). Due to limited studies in this high risk group, further studies are recommended.
