Characterization of CRKP biofilm. The structure of the polydatin (A). Growth curve analysis of bacterial growth (B) and time-killing curve of PD for CRKP (C). Inhibitory effects of PD on biofilm formation by CRKP were determined by Crystal violet assay (D). SEM images of CRKP (F). SEM images of CRKP + PD (G). CRKP morphological changes induced with or without the addition of PD were observed under an inverted microscope (E). #P < 0.05 and ##P < 0.01 vs. the CRKP alone group.
