Quantitative Immunolocalization of a P29 Protein (GRA7), a New Antigen of Toxoplasma Gondii

Production of MAG1 Antigen of Toxoplasma gondii in Escherichia coli

  Introduction : Toxoplasmosis is a parasitic infection caused by the protozoan Toxoplasma gondii it leads to serious medical problems in congenitally-infected and immunocompromised individuals, while it is quite harmless in immunocompetent individuals. Toxoplasma tissue cyst matrix protein (MAG1) induces early humoral and cell-mediated immune responses. Previous studies suggested recombinant M...

Recombinant MAG1 Protein of Toxoplasma gondii as a Diagnostic Antigen.

The aim of this study was to evaluate the potential diagnostic usefulness of the full-length recombinant Toxoplasma gondii MAG1 protein by determining the levels of specific IgM and IgG antibodies in mouse and human sera obtained from individuals with acute and chronic toxoplasmosis. The obtained results revealed that IgG antibodies against MAG1 are a sensitive and specific marker of T. gondii ...

Bacterial Production of Dense Granule Antigen GRA8 of Toxoplasma gondii

Background: Dense granule antigens (GRA antigens) of Toxoplasma gondii induce strong antibody response in humans and are considered as useful diagnostic antigens. Previous studies reported expression of amino terminal GRA8 protein in fusion with large tags such as glutathione-S-transferase. The present study aimed to produce soluble full length immunogenic GRA8 in bacteria. Methods: GRA8 comple...

Evaluating the serological applications of Toxoplasma gondii rhoptry protein 1 (ROP1) antigen

Introduction: Toxoplasma gondii (T. gondii) is distributed worldwide and infects most species. The serious incidence and severe or fatal injury caused by T. gondii infection clearly indicates the necessity for the event of a vaccine. The current study goals were to evaluate serological applications of Toxoplasma gondiirhoptry protein 1 (ROP1) ...
