Potential synergistic activity of quercetin with antibiotics against multidrug-resistant clinical strains of Pseudomonas aeruginosa
Fig 5
Effect of antibiotic-quercetin combinations at lowest FICi on biofilm.
Percentage effective combination of antibiotics with quercetin showing reduction in the biofilm. (a) Percentage of inhibition of biofilm formation (b) Biofilm cell viability of the treated pre-formed biofilms. (a) The bacteria were grown in 96-well plate in presence of antibiotic-quercetin combination and biofilm intensity was assessed by crystal violet staining. (b) Biofilm viability was tested after treating the pre-formed biofilms in 96-well plate with antibiotic-quercetin combinations.
