Background and Objectives: Toxoplasmosis is one of the most prevalent parasitic diseases in Brazil and occurs in healthy individuals with few or no symptoms. The aim of this study was to determine the prevalence of IgG and IgM antibodies to T. gondii in the serum of blood donors from Cuiabá, Mato Grosso. Methods: This was an observational cross-sectional study with 633 serum samples from blood donors at the Cuiabá Blood Center. A total of 633 serum samples from blood donors were obtained to investigate the prevalence of anti-T. gondii antibodies in Cuiabá, Mato Grosso. Results: The seroprevalence of T. gondii infection was 323/633 (51%). A total of 314/633 (49%) samples were seroreactive for IgG for T. gondii antibodies and nine (1.4%) samples with inconclusive results. In addition, 10/633 (1.57%) samples with IgM for T. gondii and 11 (0.1%) samples were inconclusive. Statistical analyses revealed significant differences for the presence of IgG for T. gondii in the stratifications by age, adults between 20-60 years of age, (p=0.000) and brown skin color (p=0.002). While for the presence of IgM for T. gondii, the variable geographic region of Cuiabá south (p=0.030) was also statistically significant. Conclusion: Based on the data obtained, it is inferred a relatively high prevalence of individuals with positive IgG antibodies for T. gondii in the blood samples of the tested donors, suggesting a chronic or past infection.
