Comparison between Toxoplasma gondii DNA and specific immunoglobulins during pregnancy.
Early diagnosis of toxoplasmosis in pregnant women can be of great help in early intervention and prevention of congenital disorders that usually lead to fetal death. The purpose of the present study was to evaluate nested PCR amplification of the B1 gene of Toxoplasma gondii before and after treatment and in comparison to serological follow-up during treatment. The efficiency of treatment on the bases of PCR detection of T. gondii DNA was statistically significant, while it was insignificant when anti-toxoplasma specific IgM and IgG antibodies were used. PCR detection of T. gondii DNA when performed on whole blood is a rapid, sensitive and specific diagnostic procedure and is a valuable tool for establishing the diagnosis of T. gondii infection in women before or during pregnancy.
