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...

BACKGROUND Human cytomegalovirus (CMV) is an ubiquitous pathogen capable of modulating the host immune system. Immune dysfunction is common during CMV infection and includes autoimmune phenomena. Here we focus on a case of primary CMV infection associated with encephalopathy in a patient with a rudimentary spleen. We discuss diagnostic challenges and immunological aspects as well as the hypothe...

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...

Background: There are no detailed reports in the literature on maternal cytomegalovirus antibody screening for universal newborn hearing (UNHS) referral patients. We examined results and estimated incidence of primary infection among UNHS Methods: During September 2013–March 2021, fresh urine samples were collected first week after birth from 98 neonates with at 15 obstetrical institutions Mie,...

objective: a descriptive study was carried out to determine the significance of igg-affinity in the serological diagnosis of rubella infections in pregnancy. materials and methods: a total of 92 pregnant women who had never received antirubella vaccines were recruited by simple random selection and did not exceed 24 weeks of gestation were recruited from the antenatal clinics of the university ...

BACKGROUND Acute toxoplasmosis in pregnant women presents a high risk of Toxoplasma transmission to the fetus. Early diagnosis is difficult, especially when serological testing for IgG/IgM antibodies fail to differentiate between a recent and a past infection. In this case, we rely on IgG avidity or PCR assays. OBJECTIVES The aim of this study was to compare conventional ELISA and IgG avidity...

Serological tests for Toxoplasma gondii are inadequate because antibody production either fails or is significantly delayed. This study in eastern Iraq investigated the IgG-avidity ELISA test for detecting recent T. gondii infections among pregnant women and compared immunological methods and PCR as molecular assays in the diagnosis of T. gondii. Serums samples were taken from 130 pregnant wome...

Congenital cytomegalovirus (CMV) is the leading infectious cause of sensorineural hearing loss and delayed psychomotor development. Viral transmission to the fetus is far more likely to occur following a primary than a secondary maternal infection. Primary prevention seems to be the best means to reduce the burden of congenital CMV due to the lack of treatment options during pregnancy. We evalu...
