FIG. 4.

Reduction of biofilm formation by a range of pathogenic and asymptomatic-infection-causing UTI isolates by preconditioning of the polystyrene microtiter plates with the total extract (white bars) or the isoelectric extract (black bars). The biofilms were grown statically in minimal medium 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.
