Differences in glucose uptake between studied groups of strains in relation to biofilm surface (a) and biofilm biomass (b). Filled square strains isolated from patients with urinal infections, filled circle strains isolated from other non-urinal infections, open triangle strains isolated from birds, open diamond strains isolated from healthy people. Vertical line 95 % confidence interval around mean. Dotted line joins strains that differed significantly according to Neuman–Keuls post hoc test at P < 0.05
