Answer

Although not a primary cause of bronchiectasis, P aeruginosa often causes chronic bronchial infection in patients with non-CF bronchiectasis via a mechanism involving biofilm formation and the release of virulence factors. This suggests that Pseudomonas species may promote disease progression, and that infection with these species may be related to worsening lung function and increased morbidity and mortality. [24]
