Trypanosoma cruzi. Surface antigens of blood and culture forms
The surface polypeptides of both cultured and blood forms of Trypanosoma cruzi were iodinated by the glucose oxidase-lactoperoxidase technique. Blood-form trypomastigotes (BFT) isolated form infected mice displayed a major 90,000-Mr component. In contrast, both epimastigotes and trypomastigotes obtained form acellular cultures expressed a smaller 75,000-Mr peptide. Both major surface components...
متن کاملSurface antigens of metacyclic trypomastigotes of Trypanosoma cruzi.
The surface antigen makeup of metacyclic trypomastigote forms of strain G of Trypanosoma cruzi, which produce a subpatent infection in mice, differed from those of the virulent strains Y and CL. A 100,000-molecular-weight protein, barely detectable on the Y or CL cell surface, appeared as the main surface antigen of the G metacyclic trypomastigotes. In addition, the G metacyclic forms differed ...
متن کاملImmunoglobulin A antibodies to Trypanosoma cruzi antigens in digestive forms of Chagas' disease.
In an attempt to find a serological marker for the diagnosis of chronic digestive forms of Chagas' disease, we compared amastigote and trypomastigote antigens obtained from immunosuppressed mice infected with Trypanosoma cruzi (Y strain) with conventional epimastigote antigens to search for immunoglobulin A (IgA) antibodies. A total of 255 serum samples from patients with acute and chronic (ind...
