Figure 4. Ectopic expression of fimL decreases cAMP.
cAMP levels were measured in (A) PAO1ΔcpdA or (B) PA103 with p (empty vector) or pfimL-FL (vector with fimL-3X-FLAG). Shown are mean values of 3 experimental repetitions performed in triplicate. Error bars indicate SD. (***) P<0.001 compared to the respective strains containing vector only and grown in the absence of Ca2+.
