Abstract Pseudomonas aeruginosa causes antibiotic-resilient acute and chronic pneumonia, but the mechanisms by which it adapts to airway environment are poorly understood. Here, we investigated P. pathoadaptive in tissue-engineered human organoids. Using transposon sequencing situ, decoded how survives on mucosal surface during antibiotic treatment. Biofilm formation emerged as a major driver of colonization. Mutants that extensively produce biofilms mucus show limited exploratory behavior, limits nutrient access, slowing down their growth. Conversely, biofilm-dwelling better tolerate antibiotics via biophysical mechanisms. Finally, can shelter less-tolerant more cytotoxic strains, thereby contributing genotypic heterogeneity. must therefore adapt conflicting physical biological selective pressures initiate infections.
