Figure 3

Chemotaxis of green fluorescent protein (GFP)-labeled P. aeruginosa PAO1 toward bovine bile using cystic fibrosis-derived bronchial epithelial (CFBE) cells. Confocal microscopy images (10×) of the chemoattraction of GFP-labeled PAO1 toward 0.03% and 3% (w/v) bovine bile on CFBE cells at times 0–10 min (two top panels). Chemotaxis buffer (CB) with no response is shown for contrast (below panel). PAO1 is attracted to bovine bile in an intact respiratory CFBE cell model, as illustrated in Figure 1.
