Respiratory cystic fibrosis with Pseudomonas aeruginosa colonization

Respiratory cystic fibrosis with *Pseudomonas aeruginosa* colonization refers to the persistent or recurrent presence of the opportunistic gram-negative bacterium *Pseudomonas aeruginosa* within the tracheobronchial tree of patients with cystic fibrosis Colonization often transitions from early, intermittent non-mucoid strains to chronic infection characterized by biofilm-forming, mucoid phenotypes that resist host defenses

In this population, defective cystic fibrosis transmembrane conductance regulator (CFTR) function leads to dehydrated, hyperviscous airway secretions and impaired mucociliary clearance, creating an ideal niche for bacterial adherence and proliferation

This clinical state triggers sustained airway inflammation, accelerated pulmonary architecture damage, worsening airflow obstruction, and an elevated risk of acute pulmonary exacerbations
