Pulmonary microbiotacomponents in bronchiectasis patients receive repeated antibiotic exposures, whereas previous studies on the effects ofantibiotic treatment focused on typical pathogens rather than commensals. By integrating experimental evolution withsingle-cell resolution, the authors reveal a multifaceted strategy by which Neisseria subflava, a common airwaycommensal associated with bronchiectasis, exploits antibiotic selection to transition towards pathogenicity.
