Resumo
To determine the prevalence of toxoplasmosis and to identify the main factors associated with seroreactivity in
pregnant women cared for at two reference centers in a city in Northeast Brazil. METHODS: A cross-sectional study was
conducted on 561 pregnant women at two high-risk prenatal reference centers in a city in Northeast Brazil. All women
were interviewed using an epidemiological questionnaire and had their blood samples collected for the following
serological tests: anti-Toxoplasma gondii IgG and IgM (ELISA), IgG avidity test, and polymerase chain reaction (PCR).
Statistical analysis was carried out using SPSS version 18.0 for Windows, calculating odds ratio, confidence interval
of 95% and with the level of significance set at 5%. RESULTS: Seroreactivity for toxoplasmosis was detected in 437
women (77.0%), susceptibility in 124 (22.1%) and active infection in 5 (0.9%). There was no significant association
between seroreactivity for toxoplasmosis and age, location, income, education, availability of sewage, number of
pregnancies or gestational age. The variables significantly associated (p≤0.05) with seroreactivity were multiparity
(p=0.03) and living with stray dogs (p=0.01). CONCLUSIONS: This study identified high seroreactivity for toxoplasmosis
among patients seen during prenatal care, as well as factors associated with seroreactivity. Appropriate guidelines
about primary preventive measures should be emphasized and quarterly serological monitoring is recommended for
pregnant women in this city and elsewhere in the Northeast of Brazil.
