Gene expression analysis of virulence factors (exoS, exoY, pvdS) in P. aeruginosa during exacerbation and stable phases. Fisher’s method. Overexpression (green color) was considered when the corresponding mRNA level was ≥ 2-fold higher than that of ATCC PA14. Otherwise, the result was considered negative if < 1-fold higher, and borderline if between 1- and 2-fold higher.
