    Cystic fibrosis (CF) is caused by mutations in the CFTR gene, leading to impaired ion transport and chronic airway infections.

  • 2

    CF airway infections are polymicrobial, dominated by pathogens like Pseudomonas aeruginosa and Staphylococcus aureus, causing lung damage.

  • 3

    CFTR modulators improve airway hydration and mucociliary clearance but do not eliminate chronic infections in most patients.

  • 4

    Chronic infections in CF are associated with accelerated lung function decline and increased mortality risk.

  • 5

    Diverse bacterial communities in CF airways decline in diversity over time, with traditional pathogens dominating as disease progresses.
