A) Quantification of biofilm formation by crystal violet staining. Eight independent replicates were done. Student´s t-test was done, values are means and bars indicate the standard deviation. B) SEM analysis of bacterial biofilm on plastic surface at the liquid-air interface of the A. baumannii strains a) ATCC 17978, b) MAR002, c) MAR002Δ11085 and d) MAR002Δ11085 complemented. All micrographs were taken at 5,000x magnification. Bars indicate the scale marks (2 μm).
