a) Mice survival rate. Priming of the respiratory tract with L.psb (1 × 106 CFU/mouse) or L.rff (6 × 106 CFU/mouse) resulted in survival in response to P. aeruginosa infection (6 × 106 CFU/mouse). Statistical significance: *, p < 0.001 for the L.rff + PAO1 and L.psb + PAO1 groups compared to the control PAO1 group, and p < 0.05 for the L.rff + PAO1 group compared to L.psb + PAO1 group. b) Pulmonary P. aeruginosa burden measured on total lung homogenates. Priming of the respiratory tract with L.psb (2 × 105 CFU/mouse) or L.rff (4 × 106 CFU/mouse) 18 h prior to P. aeruginosa infection (6 × 106 CFU/mouse) enhanced the clearance of P. aeruginosa. Statistical significance: *, p < 0.05 compared to the control PAO1 group
