“…Variables such as urbanization, changes in lifestyle and habits, and better conditions of environmental sanitation and food care appear to influence T. gondii infection prevalence among adults 17 , which may explain the observed reduction in infection levels over time in our study. Although desirable, lower circulation of the pathogen in a community ultimately increases the number of women of childbearing age who are susceptible to infection and, consequently, lowers the risk of congenital infection.…”

Introduction: The prevalence of Toxoplasma gondii infection varies markedly among different populations, especially depending on factors related to socioeconomic development and eating habits. Cássia dos Coqueiros is a small city in Brazil with rural characteristics and increased risk factors traditionally associated with T. gondii infection. Methods: We carried out a cross-sectional study involving 970 inhabitants aged 18 years or more, selected from patients of the local health unit and home visits in urban and rural areas. Each participant completed a survey with questions regarding demographic, socioeconomic, and risk factors for toxoplasmosis. Blood samples from participants were tested for presence of IgG and IgM antibodies against T. gondii using a chemiluminescent microparticle immunoassay. Results: The prevalence of IgG and IgM antibodies was 62.3% and 2.5%, respectively. Variables that proved to be independent predictors of infection were age, low levels of education, and previous diagnosis of toxoplasmosis. Conclusions: The high prevalence of toxoplasmosis serological markers in this adult population highlights the need to promote preventive practices, especially those directed toward women of childbearing age, in this part of Brazil.

“…Los modos de transmisión más relevantes en el ser humano son: vía congénita (transmisión vertical), consumo de carnes infectadas con bradizoítos, deglución de ooquistes del ambiente por medio de alimentos o agua contaminada con materia fecal de gatos y por medio de trasplante de órganos infectados y/o transfusiones con quistes o zoítos de T. gondii 2 .…”

“…En general, la toxoplasmosis es una infección que cursa de forma asintomática y autolimitada en individuos inmunocompetentes, mientras que puede llegar a causar complicaciones y daños serios al feto si la mujer se infecta durante el embarazo, así como la infección grave en pacientes inmunocomprometidos 2,4 .…”

“…A. es considerada una de las principales causas de hospitalización y muerte atribuida a enfermedades transmitidas por los alimentos 3,5 . La distribución de la infección en todo el mundo es variable, incluso dentro de un país, probablemente debido a diferencias ambientales, tales como saneamiento, clima y humedad; socio-económicas y culturales de un lugar en particular y sus residentes, con tasas de prevalencia en los países en desarrollo que varían entre 30 y 60% 2,6 . En Chile, la toxoplasmosis es endémica, presentando amplias diferencias regionales.…”
