الإجابة: C. Pseudomonas aeruginosa
Lifelong recurrent infections, daily copious sputum with green exacerbations and cystic changes in both lungs describe bronchiectasis (CF-type picture). The cohort's notes list Pseudomonas aeruginosa as the pathogen of bronchiectasis patients and specifically of CF. H. influenzae is the tempting option, but the notes link it mainly to COPD-related bronchiectasis.
