Figure 6.

Comparison of survival of bacterial biofilms formed by multidrug-resistant and pan-susceptible strains. Average percentage of metabolic activity of five MDR versus five PS biofilms after (A) 4 min of bleach, (B) 1 min of 55% ethanol, (C) 1 min of 70% ethanol, (D) 2 min of 0.5% BAC, and (E) 1 min of 0.61% DDAC exposure. The average metabolic activity is displayed; error bars represent standard deviations. A p-value of ≤0.05 was considered significant. No significant differences were observed.
