Background: Toxoplasmosis is well known as an important infection in pregnant women. Although many serologic methods are available, diagnosis of early Toxoplasmosis may be extremely difficult. Objective: To detect the Toxoplasma IgG antibodies developed at the early stage of infection in pregnant women. Methods: 225 pregnant women, who were in the 2nd to 4th month of their pregnancy, enrolled i...

background: toxoplasma specific igm antibodies; the common serologic marker in diagnosis of acute toxoplasmosis has its own limitations. confirmatory testing with other markers, introduced as a complementary tool in distinguish acute and chronic infections is unusual in iran. in the present study, we investigated the cor-relation between the results of igm elisa, iga elisa, and igg avidity test...

objective: toxoplasma gondii infection, an intracellular parasite, is often asymptomatic or is caused by different clinical diseases without being detected. evaluation of igg, iga, and igm in order to diagnose the pending toxoplasmosis may confront some problems. several researches has showned that toxo igg avidity can be useful in the recent active toxoplasmosis. in current study, modification...

Avidity of immunoglobulin G (IgG) is defined as its binding strength to target antigen. As a consequence affinity maturation the IgG response, avidity maturing well. Therefore, acute infections are characterized by low-avidity IgG, whereas past usually associated with high-avidity IgG. also observed optimal vaccination. has been shown play significant role in protective humoral immunity many mi...

Objective Objective: Toxoplasma gondii is one of the major causes of abortion in pregnant women. Most cases of abortion occur in the acute phase of infection and early pregnancy. In this study, the seroprevalence of anti-Toxoplasma gondii IgM and IgG antibodies was investigated in women with first spontaneous abortion. Also to determine the acute and chronic infections, all IgM and IgG positive...

To perform IgG avidity immunoblotting assay for detection of acute toxoplasmosis, 100 serum samples were collected from Tehran, Iran. The presence of Toxoplasma-specific IgG and IgM antibodies were checked by commercial Trinity kit. Samples were categorized in acute and chronic phases of Toxoplasma gondii infection according to IgG avidity ELISA. IgG avidity immunoblotting was performed, and an...
