Implication

Longitudinal evaluation reveals chronic P. aeruginosa infection impacts lung function in cystic fibrosis rat models, suggesting new therapeutic approaches.

Key Points

This research aims to create a long-lasting Pseudomonas aeruginosa infection in cystic fibrosis rat models to study its effects.
Developed a localised single-lung infection using a bronchoscope.
Utilized clinical CF bacterial isolates embedded in agar beads.
Monitored cohorts at specific intervals (7, 14, 21, and 63 days).
Assessed bacterial load, lung function mechanics, and conducted histopathological analysis.
Bacteria persisted for 63 days in all genotypes with stable health.
Localized acute bronchopneumonia progressed to chronic interstitial pneumonia.
Displayed changes in lung mechanics by day 63, indicating respiratory impact.
