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

Figure 1

Effect of chlorogenic acid (32 mg mL−1) applied to a blank filter paper disk on MHA plate inoculated with S. maltophilia ATCC 13637. Caffeic acid which is an ester of chlorogenic acid also showed similar zone size. CF:caffeic acid, CH:chlorogenic acid, TMP/SMX:trimethoprim/sulfamethoxazole (30 μg), and DMSO:dimethyl sulfoxide (10%).
