WESTERN BLOT DETERMINATION OF IgG AVIDITY IN PRIMARY AND SECONDARY SYPHILIS
ثبت نشده
چکیده
In this study, we analysed IgG avidity to p 15.5 kD, p 17 kD and p 47 kD antigens by a new avidity assay termed avidity western blot. The determination was performed in two groups. Group I consisted of 27 patients with primary and secondary syphilis and group II comprised 10 subjects with latent syphilis. We found that low avidity antibodies were directed against the p 17 kD and p 47 kD antigens in group I and against the p 47 kD antigen in group II. No low-avidity IgG antibodies were detected by ELISA, a routine method for avidity assessment.

Changes of serum IgG antibody reactivity to protein antigens of Treponema pallidum in syphilis patients after treatment.
The changes of serum IgG antibody reactivity to protein antigens of Treponema pallidum after treatment of syphilis were observed using sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) and Western blot. Until 9 to 12 months after treatment, it was seen that there was a loss of several antibodies and some diminution in their reactivity in primary, secondary and early latent sy...
متن کاملAvidity of immunoglobulin G directed against human cytomegalovirus during primary and secondary infections in immunocompetent and immunocompromised subjects.
Diagnosis of primary human cytomegalovirus (HCMV) infection is accomplished exclusively by serologic testing. Among the possible methods, the determination of immunoglobulin G (IgG) avidity is one of the least explored. In this work, we used a commercially available kit to test anti-HCMV IgG avidity in 336 serum samples from pregnant women and transplant recipients undergoing virologically prov...
متن کاملEvaluation of the recombinant protein TpF1 of Treponema pallidum for serodiagnosis of syphilis.
Syphilis is a chronic infection caused by Treponema pallidum subsp. pallidum, and diagnosis with sensitive and specific methods is a challenging process that is important for its prevention and treatment. In the present study, we established a recombinant protein TpF1-based indirect immunoglobulin G (IgG) enzyme-linked immunosorbent assay (ELISA) and a Western blot assay for human and rabbit se...
متن کاملSerodiagnosis of toxoplasmosis. The impact of measurement of IgG avidity.
The development of IgG avidity assays has revolutionised serological diagnosis of Toxoplasma infections. The measurement of IgG avidity has shown its power in various clinical settings, especially in situations where timing and differentiation of primary and secondary infections is crucial. However, no laboratory test performed alone is self-sustained, whereby the diagnostic strategy of choice ...

Although heterotypic secondary infection with dengue virus (DENV) is associated with severe disease, the majority of secondary infections are mild or asymptomatic. The mechanisms of antibody-mediated protection are poorly understood. In 2010, 108 DENV3-positive cases were enrolled in a pediatric hospital-based study in Managua, Nicaragua, with 61 primary and 47 secondary infections. We analyzed...
