Once a patient develops bronchiectasis, many of these same organisms colonize the damaged bronchi and may cause ongoing damage and episodic infectious exacerbations. The organisms found most typically include Haemophilus species (47-55% of patients) and Pseudomonas species (18-26% of patients). [22, 23]
