| Objective: To identify serodiagnosis and quantification of Toxoplasma gondii (T. gondii)
infection among pregnant women in Salmas, northwest of Iran. Methods: In this crosssectional
study, 276 blood samples were collected from pregnant women referred to the health
care centers in Salmas city. The demographic variables were also recorded. Titers of anti-
Toxoplasma IgM and IgG antibodies (Ab) were determined using the chemiluminescence
immunoassay. Quantitative real-time PCR targeting the T. gondii repeated element gene was
also performed on the blood sample. Results: Out of all, 19.92% (55/276) and 2.17% (6/276)
patients were seropositive for anti-Toxoplasma IgG and IgM Ab, respectively. Moreover, the
presence of T. gondii DNA was observed in 12.31% (34/276) blood samples. A significant
relationship was observed between the IgG Ab seropositivity and contact with the cat as a
risk factor (P=0.022). Conclusions: The seroprevalence rate of T. gondii infection in pregnant
women is relatively low. Consequently, the seronegative pregnant women are at risk, and a
considerable rate of positive blood samples for the presence of parasite’s DNA should not be
ignored. Besides, quantitative real-time PCR could be considered as an accurate method for
diagnosis of acute toxoplasmosis especially when the precise results are of the most importance
in pregnancy. Limiting contact with cats is also suggested for pregnant women. |
