SMOX and infection: After infection of A549, 16HBE14o- and CFBE41o- monolayers with the different P. aeruginosa strains for 3 h at a multiplicity of infection (MOI) = 100, the adhesion patterns of the PAO1, PA14, PAET1, PAET2, and PAET4 strains showed no significant changes (p > 0.05) when adhering to the same epithelial cell type (Figure 1 and Table S1).
