Figure 6: The effects of L-NAC on Pseudomonas aeruginosa motility. Subinhibitory concentration (1/16, 1/8 and 1/4) of both formulations (F-NAC & L-NAC) was added to different concentrations of agarose plates and motility was examined. (A) Swarming (0.5% agarose w/v), (B) swimming (0.3% agarose w/v) and (C) twitching (1% agarose w/v). P values were considered significant when compared to control *** P<0.001, ** P<0.01, * P<0.05. All experiments were repeated 3 times in triplicates.
