Antibiofilm Activity and Synergistic Effects of Thymol-Loaded Poly (Lactic-Co-Glycolic Acid) Nanoparticles with Amikacin against Four Salmonella enterica Serovars

Figure 1

Quantification at 570 nm of biofilm biomass of Salmonella enterica serovars by staining with safranin 1%. MBP: moderate biofilm producer; SBP: strong biofilm producer. The dashed line represents the value of the optical density of control (ODC) at 570 nm.
