FIGURE 6.
Effect of the QQ enzyme Aii20J (20 μg/mL), DNase (2 U/mL) or both on biofilm formation by A. baumannii ATCC® 17978TM and different multidrug-resistant clinical strains presenting different motility patterns (López et al., 2017). Biofilms were cultivated on 18 mm × 18 mm glass coverslips in LS-LB during 24 h at 37°C and stained with crystal violet (n = 3). The cultures were inoculated with cells from an agitated (A) or a static (B) culture. Asterisks indicate statistically significant differences in comparison with the untreated control (Mann–Whitney test, p < 0.05).
