Concentration-dependent inhibitory activity of celastrol on biofilm formation as revealed by; (A) light microscopy and (B) SEM images. Percentage of biofilm inhibition by celastrol evaluated by the crystal violet quantification assay on; (C) polystyrene plate and (D) polypropylene tube. Data shown represent the mean ± standard of error from triplicate experiments. A P value < 0.05 was considered statistically significant using Student’s t test
