摘要：

The immune response to Pseudomonas aeruginosa strains could be influenced by differences in antibiotic resistance and virulence. At the present time, it is unclear which type of immune responses enables uncontrolled invasion of opportunistic pathogens. The conditional pathogenicity of Pseudomonas aeruginosa served as an inspiration to begin a study on this bacterium. The aim of this study was to gain insight into selected parameters describing immune responses with regards to the adaptable agents of this pathogen. For the analysis of the specific immune response, the potential of Pseudomonas aeruginosa to stimulate lymphocytes, including Th17 lymphocytes, dendritic cells and other components of the adaptive immune response, was examined. The highest percentage of CD83+CD1a-HLA-DR++ cells was found after stimulation with lysates of strains isolated from the patients with severe systemic infection. We found statistically significant differences in percentages of HLA-DR+ PBMCs and MFI of HLA-DR between groups of Pseudomonas aeruginosa strains isolated from the patients with different clinical courses of infection. Our results suggest that the clinical course and outcomes of Pseudomonas aeruginosa infections are not associated with impairment of the specific immune response.
