title: [Seroepidemiology of Toxoplasma gondii in elderly individuals treated under the Family Health Strategy, Porto Alegre, Rio Grande do Sul, Brazil].
abstract: The aim of this study was to evaluate the seroprevalence of Toxoplasma gondii and relate it to the socioeconomic, hygienic, sanitary and health conditions of the elderly of the Family Health Strategy (FHS) in the city of Porto Alegre, Rio Grande do Sul, Brazil. The research involved a cross-sectional study in which a questionnaire with epidemiologic questions was applied and blood samples were taken. The assessment of IgG and IgM anti-T. gondii was performed using the ELISA technique. Seroprevalence was evaluated among 599 elderly individuals with 88% for IgG anti-T. gondii and with 0.8% for IgM. In the multivariate analysis, the variables that associated themselves independently with positive IgG were age range, personal income and wearing spectacles. Those associated with positive IgM were age, self-rated health and wearing spectacles. The results call attention to the high prevalence of IgG anti-T. gondii in elderly individuals in the FHS in Porto Alegre, generating concern in the event that the reactivation of toxoplasmosis and the development of more severe symptoms of this infection occur.
