Evaluation of the Korean isolate-1 tachyzoite antigen for serodiagnosis of toxoplasmosis.

An evaluation of a recombinant multiepitope based antigen for detection of Toxoplasma gondii specific antibodies

BACKGROUND The inefficiency of the current tachyzoite antigen-based serological assays for the serodiagnosis of Toxoplasma gondii infection mandates the need for acquirement of reliable and standard diagnostic reagents. Recently, epitope-based antigens have emerged as an alternative diagnostic marker for the achievement of highly sensitive and specific capture antigens. In this study, the diagn...

Evaluation of Recombinant SAG1, SAG2, and SAG3 Antigens for Serodiagnosis of Toxoplasmosis

Serologic tests are widely accepted for diagnosing Toxoplasma gondii but purification and standardization of antigen needs to be improved. Recently, surface tachyzoite and bradyzoite antigens have become more attractive for this purpose. In this study, diagnostic usefulness of 3 recombinant antigens (SAG1, SAG2, and SAG3) were evaluated, and their efficacy was compared with the available commer...

Preparation and Evaluation of Stained Pertussis Antigen for Serodiagnosis of Whooping Cough

Evaluation of Enzyme Linked Immunosorbent Assay, Utilizing Native Antigen B for Serodiagnosis of Human Hydatidosis

Background: Hydatidosis is one of the cosmopolitan parasitic zoonoses caused by the larval stage of Echinococcus granulosus. Diagnosis of hydatidosis is still an unresolved problem. Serological tests using crude antigens for diagnosis of E. granulosus are sensi-tive, however their specificity are not satisfactory. Therefore, WHO recommended spe-cific serological methods using specific antigens,...

کلونینگ ژن بیان کننده آنتی‌ژن سطحی 1(SAG1) توکسوپلاسما گوندی و ترانسفورماسیون آن در دو سویه DH5a و TG1 اشرشیاکلی

    Background & Aim: Toxoplasmosis is caused by a protozoan parasite called toxoplasma gondii. SAG1 is an antigen which only exists in tachyzoite stage. This antigen which has two glycoforms is a conformational antigen. The aim of this research is to study cloning of SAG1 gene in PTZ57R and transformation of recombinant plasmid in E.coli(TG1 & DH5a). Material & Method: Tachyzoites of T.gondii ...
