Congenital toxoplasmosis is a disease with sever clinical manifestations in newborns so screening of pregnant
women is crucial. This study was aimed at evaluating the latest status of toxoplasmosis in pregnant women and its
respective risk factors in the northeast of Iran. This survey was conducted between 2013 and 2015 on 350 pregnant
women. Blood samples were taken from the participants and their serums were separated. Anti-Toxoplasma IgG
and IgM were assessed in the serum samples using ELISA method. Moreover, a questionnaire about toxoplasmosisrelated
risk factors and other information was completed by each participant. Of the 350 pregnant women studied,
110 (31.42%) were positive for IgG and 12 (3.42%) for IgM. The IgM-positive subjects were also positive for IgG.
Age of pregnancy, residence area, contact with cat, degree of meat cooking, unwashed raw vegetable or fruit
consumption, raw milk consumption, and history of miscarriage were toxoplasmosis-related risk factors considered
in this study, the results showed that all these factors were statistically significant in IgG-positive subjects. In IgMpositive
subjects, contact with cat, degree of meat cooking, unwashed raw vegetables, fruits consumption, and
history of miscarriage were among the more important risk factors. The new cases of toxoplasmosis are being
occurring in the pregnant women in the region under the study and therefore these pregnancies are uncertain.
