Figure 3From: The evolution of antibiotic susceptibility and resistance during the formation of Escherichia colibiofilms in the absence of antibioticsStandard deviation (in pixels) of the diameters of zones of inhibition (ZOI) across ancestor (time zero) and bacteria isolated from biofilms at 15, 30, and 60 days. Individual replicates appear as distinct colors connected with a line. The variance across ZOI measurements of the ancestor is plotted at time 0 as an open circle.Back to article page
