FIG. 5.

Reduction of biofilm formation by the UTI isolates during growth in human urine on polystyrene microtiter plates preconditioned with the total extract (white bars) or the isoelectric fraction (black bars). The biofilms were grown with agitation for 16 h at 37°C. The absorbance values indicated were calculated relative to that for the uncoated control (NC). Standard deviations of the results obtained from at least three independent experiments are indicated. ABU, asymptomatic-bacteriuria strains.
