Development of adaptive immune responses following exacerbation and colonisation with these respiratory bacterial pathogens supports the pathogenic role of these organisms in the lower airway. The strain specificity of these immune responses accounts for the recurrent exacerbations seen in COPD, as these antibodies are usually not protective against antigenically different strains of the same species. OTHER POTENTIAL MECHANISMS OF BACTERIAL EXACERBATIONS Pseudomonas aeruginosa, a significant airway pathogen in bronchiectasis and cystic fibrosis, has been isolated from sputum and bronchoscopic samples in COPD exacerbations, usually with underlying severe airflow obstruction.
