| Popis: | To test the hypothesis that a Pseudomonas aeruginosa flagella (FLA) vaccine, intramuscularly administered, elicits specific antibodies in the respiratory tract, antibody titers against FLA were determined in sera and bronchoalveolar lavage (BAL) fluids of 10 healthy human adults before and after immunization. Immunization produced significantly increased anti-FLA antibody titers in all sera (mean reciprocal titers: IgG: 26,711; IgA: 2,767; IgM: 421) and on respiratory epithelial lining fluids (mean reciprocal titers: IgG: 112; IgA: 76; sIgA: 26). Significant differences in class-specific serum and BAL anti-FLA titers suggested airway antibody production. The study shows that parenteral immunization provides not only high systemic antibody titers but also local antibody production in the human respiratory tract. |
