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...
متن کاملImmunohistochemical demonstration of Toxoplasma gondii.
A peroxidase-antiperoxidase method that demonstrates both free and encysted toxoplasmata in routinely prepared histologic sections is described. This technic and ultrastructural study were employed to confirm the presence of Toxoplasma gondii in the infected tissues of an immunosuppressed patient who had postmortem examination. An immunohistochemical method may be an aid in the diagnosis of tox...
متن کاملBacterial 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...
متن کاملA shorter immunoperoxidase technique for the demonstration of carcinoembryonic antigen and other cell products.
A reliable immunoperoxidase schedule for the cellular demonstration of tumour and normal cell products which can be completed in well under two hours is described. The preparations are as clear and readable as those stained by routine histological techniques and should form a valuable adjunct in research and diagnostic studies.
متن کاملSerological Evaluation of Experimental Toxoplasma gondii Infection in Cats by Using Immunoblotting Based on an Affinity Purified Surface Antigen
Toxoplasma gondii is an apicomplexan parasite that infects human and almost all warm-blooded animals. The life cycle of the parasite includes an asexual reproduction in intermediate hosts (Mammals and birds) and a sexual reproduction in definitive hosts (Felidae). Cats are both the intermediate and the definitive host for T. gondii. The aim of this study was to investigate anti-T. gondii antibo...
