Background: Toxoplasma gondii is one of the most prevalent parasites of human and warm- blooded animals. Toxoplasmosis is important especially in two groups: pregnant women and immunocompromised patients. If women acquire the primary infection during the pregnancy, it would be life threatening or remains severe disorders for the fetus. This study was performed to evaluate the seroprevalence of T. gondii infection in pregnant women referred to Health Center in Gorgan City, Golestan Province, northern Iran.
Methods: Serum samples were collected from pregnant women referred to Health Center in Gorgan City, south eastern Caspian Sea. Anti- Toxoplasma IgG and IgM antibodies were determined by commercially ELISA kits and the relation of infection with socio-demographic and risk factors such as age, education, occupation, cat ownership, soil contact and some other factors was studied.
Results: From 555 tested sera of pregnant women referred to Health Center in Gorgan, 39.8% had IgG antibodies against T. gondii and 3.4% were positive for IgM antibodies. A significant correlation was seen between T. gondii infection with age and soil contact.
Conclusion: About 60% of pregnant women in Gorgan City are seronegative against T. gondii, so they should considered as at risk persons.
