The inhibition effect of Erythromycin E against Rs1115. a Images of agar diffusion assays showing the inhibition zones of Rs1115 in response to different concentrations of Erythromycin E. The compound was applied in a gradient from 0.125 to 256 µg/mL, with negative controls CK (nutrient broth medium) and CK (dimethyl sulfoxide, DMSO). The mean diameters of inhibition zones (± standard error) are indicated below each corresponding plate. b Images of bacterial growth in liquid NB medium supplemented with different concentrations of Erythromycin E. Optical density (OD600) measurements are provided, showing bacterial turbidity at 24 h post-incubation. c Quantification of inhibition zones from the agar diffusion assay. d Growth inhibition of Rs1115 in liquid culture, as determined by OD600 measurements after 24 h of incubation with different concentrations of Erythromycin E. Statistical significance in these graphs is indicated (***P < 0.001; NS, not significant)
