Indole impregnated silicone Foley catheter inhibit the biofilm formation by Proteus mirabilis. Quantification of the reduction in P. mirabilis crystalline biofilm on indole extract (Zch127) impregnated catheter compared to DMSO control, where (A) Reduction in adhered viable bacterial cells of P. mirabilis ATCC12453, and isolate P8 measured by drop plate method after 24 h of incubation, data are represented as median with interquartile range and (B) Reduction in biofilm biomass using crystal violet assay, data represents the mean of at least 3 biological replica, and error bars show standard deviation. Statistical difference was determined by student’s t-test, where statistical significance is represented by ***p < 0.001.
