Isolation and characterization of a recombinant antigen of Pneumocystis carinii.
Pneumocystis carinii contains a major group of antigens which migrates as a broad band of 45 to 55 kDa and 35 to 45 kDa in organisms derived from rats and humans, respectively. This complex is among the most common P. carinii antigens found in the respiratory tract and is recognized by serum antibodies of infected individuals. We have isolated a cDNA clone encoding the 3' portion of a 45- to 55...
متن کاملActive immunization against Pneumocystis carinii with a recombinant P. carinii antigen.
Mice immunized with recombinant mouse Pneumocystis carinii antigen A12-thioredoxin fusion protein developed an antibody response that recognized P. carinii antigens, as determined by Western blotting and immunofluorescence analysis. Compared to mice immunized with thioredoxin alone, mice immunized with A12-thioredoxin had significantly reduced lung P. carinii burdens after CD4+ T-cell depletion...
متن کاملPneumocystis carinii.
Although Giemsa staining has been routinely used for the detection of trophozoites and intracystic bodies in smears of bronchoalveolar lavage fluid (BAL) from patients with Pneumocystis cariniipneumonia, it does not normally stain the cyst wall. For detection ofthe cysts other stains such as toluidine Blue 'O' and methenamine silver must be used as well. Sulphation of smears before staining wit...

متن کاملPneumocystis carinii antigen detection in rat serum and lung lavage.
We developed a modified double-antibody sandwich enzyme-linked immunosorbent assay (ELISA) that detected relatively low concentrations of known Pneumocystis carinii antigen added to buffer or rat sera. Artificial immunization-derived polyclonal rabbit anti-P. carinii antibody was used on the solid phase to capture the antigen. Infection-derived (after P. carinii pneumonia) polyclonal rat anti-P...
