FIG 3.

Time-kill kinetics of T9W in combination with ciprofloxacin (A), gentamicin (B), or ceftazidime (C) against P. aeruginosa LCCI (A), P. aeruginosa LCGE (B), or P. aeruginosa LCCE (C). The activity of the combination of 0.5× LC of T9W and 0.5× LC of antibiotic (open diamonds) was compared with the results of 0.5× LC of T9W alone (open squares), 0.5× LC of antibiotic alone (open triangles), or untreated bacteria (open circles). The graphs were derived from average values of three independent trials. ∗, P < 0.01; ∗∗; P < 0.001 (compared to results for the control at the same concentration).
