BETANCUR, Carlos Alberto et al. Seroprevalence of toxoplasmosis in donors from Clínica Cardiovascular Santa María, Medellín, Colombia, 2009-2010. Infect. [online]. 2011, vol.15, n.1, pp.14-19. ISSN 0123-9392.

Introduction: Toxoplasmosis is a zoonosis of world-wide distribution. Pregnant women and immunosuppressed individuals constitute the susceptible population, reason why most of seroprevalence studies of T. gondii usually are made in these populations over those in healthy population. Objective: We sought to determine the prevalence of T. gondii infection in a sample of healthy blood donors from Medellín (Colombia). Materials and methods: Two hundred and one healthy blood donors from Clínica Cardiovascular Santa María (not selected randomly) were examined for toxoplasmosis infection between December 2000 and January 2010. Socio-demographic and behavioral characteristics acting from each participant were also obtained. Samples of venous blood were tested for anti- T. gondii IgG antibodies by using an electroquimioluminiscence assay. Results: Sixty (29.9%) of 201 donors had a reactive serology to IgG parasite antibodies. Bivariate analysis showed that the infection was related with age and schooling level (p=0,007 and p=0.025, respectively).

Keywords : Seroepidemiologic study; toxoplasmosis.
