Background & Objectives: Infection with Toxoplasma gondii can cause severe illness when transmitting to fetus or when it is reactivated in immune-suppressed persons. The aim of this study was to determine the prevalence of antibodies against toxoplasma gondii in women referring to laboratory of health center for medical examinations before marriage.
Methods: This descriptive cross-sectional study was performed on 504 samples collected from women in Arabil, Iran, in 2002. The samples were studied by indirect immunofluorescent assay (IFA) for determination of IgG and IgM antibodies to toxoplasma.
Results: The seroprevalence of IgG antibody at a titer of ³ 1:20 was 34.7%. The highest antibody titer frequency was observed in 1:20 titer (11.7%) and the lowest belonged to 1:3200 (0.4%) and 1:6400 (0.4%) titers. 20 persons (4%) showed IgM antibody against Toxoplama gondii. No statistically significant differences were observed between the prevalence of antibodies on the one hand and age and history of contact with cat or domestic animals on the other.
Conclusion: since 65.3% of these women in Ardabil were seronegative, health education is required to omit the risk factors, especially during the pregnancy.
