It is characterised by repeated infective exacerbations and bacterial colonisation. In bronchiectasis, Pseudomonas aeruginosa is a significant pathogen, associated with increased mortality and acute hospital admission [2]. P. aeruginosa is an aerobic Gram-negative rod-shaped bacterium and a common nosocomial pathogen [3].Two case reports show lack of Pseudomonas aeruginosa transmission, despite household contact, in non-cystic fibrosis bronchiectasis (NCFB). This supports evidence that in NCFB, P. aeruginosa is poorly transmitted. This affects management strategies. https://bit.ly/3PeOcHy ER -
