In Vitro Antibacterial and Antibiofilm Activities of Chlorogenic Acid against Clinical Isolates of Stenotrophomonas maltophilia including the Trimethoprim/Sulfamethoxazole Resistant Strain

Figure 2

Effect of chlorogenic acid on the viability of S. maltophilia ATCC 13637 in liquid medium (time-kill curve). S. maltophilia ATCC 13637 grown at 37°C in the presence of chlorogenic acid at concentrations of 0 (♦), 4 (■), 8 (▲), 16 (×), and 32 (●) μg mL−1 (1/2x, 1x, 2x and 4x MIC) with control (0 MIC). MIC: minimal inhibitory concentration; CFU: colony-forming units.
