Fig 2.

Boxplots of the absorbance values obtained for the clinical and environmental isolates of R. mucilaginosa in the biofilm formation assays. The clinical isolates presented a greater ability to form biofilms than did the environmental isolates (P = 0.04). The solid circle indicates the mean absorbance obtained for the group of clinical (A₅₇₀, 0.497) and environmental (A₅₇₀, 0.21) isolates. The asterisk indicates that isolate 2991B showed significantly greater biofilm formation capability (P < 0.05).
