[Toxoplasma gondii infection in pregnant women]

The aim of this study was to determine the percentage of seropositive pregnant women, i.e. of pregnant women infected with Toxoplasma gondii in order to provide an insight into the risk of developing congenital toxoplasmosis in our community.

In the period of two years, 662 pregnant women from Vojvodina were examined serologically. The enzyme-linked immunosorbent assay tests were performed to determine IgM and IgG antibodies against Toxoplasma gondii and the complement fixation test was done to detect total antibodies against Toxoplasma gondii.

Seropositivity was determined in 180 pregnant women (27.19%). Of 135 pregnant women examined in the routine control in pregnancy, 16.30% were seropositive and out of five proven, completely new Toxoplasma gondii intfections, three were detected in pregnant women who had undergone the routine check-up for no specific symptoms. A detailed analysis of the frequency of seropositive findings in relation to clinical diagnoses and the place of residence of pregnant women (urban and rural areas) was performed. At the same time, the results from the serological reactions were presented, commented and interpreted, and recommendations were given for the implementation of additional examinations (eg, IgG antibody avidity test) in order to make the accurate diagnosis.

It can be concluded that the occurrence of congenital toxoplasmosis is still a problem in our community and that the best prevention is the prompt and adequate examination of pregnant women for the presence of Toxoplasma gondii infection.
