Résumé
The aim of this study was to determine the Toxoplasma antibodies in pregnant women in Zanjan, by ELISA method. Blood samples were taken from 500 pregnant women referred to the health centers of Zanjan City, North West Iran, IgM and IgG titers were primarily evaluated. The collected data were analyzed with SPSS 11.5 using Chi-Square test. Anti Toxoplasma IgM and IgG were positive in 1.4% and 37.2% respectively. Seropositive subjects were more frequently seen in those with >30 years old compared to younger women [<20 years old]. No significant relationship was found between the seroprevalence of T. gondii infection and level of education, residence area, history of abortion and gestational age. The rate of IgM positive was low; however, a large number of the studied population were IgG positive, indicative of having a latent infection due to the past exposure to Toxoplasma parasite in this region
