( B ) Quantitative of the biofilm biomass and biofilm height by <t>COMSTAT</t> of biofilms formed by P. aeruginosa PAO1, Δ fleQ, and double mutant Δ fleQΔsagS. * *, ***, significantly different ( P = 0.0001, <0.0001, respectively) relative to PAO1 using ANOVA followed by the Bartlett’s test. Ns, not significant. ( C ) Total cellular c-di-GMP levels in 6-day-old biofilms formed by P. aeruginosa PAO1, Δ fleQ, and ΔsagS, as determined by HPLC quantitative analysis, followed by normalization relative to total cell protein content. *, P < 0.05, relative to PAO1 using ANOVA followed by Dunnett’s T3 multiple comparisons test. ( D ) Representative confocal images of 6-day-old P. aeruginosa Δ fleQ and ΔsagS biofilms and mutant biofilms expressing bfiR and gcbA. gcbA encodes diguanylate cyclase GcbA, bfiR the two-component response regulator BfiR. White bar = 100 µm. All experiments were performed in triplicate. Error bars indicate standard deviations.

    Article Snippet: .. There are a number of automatic threshold detection schemes already available in image analysis software such as COMSTAT (implemented in MATLAB) (Heydorn et al., 2000), COMSTAT2 (implemented in ImageJ) (Vorregaard, 2008), Imaris (Imaris, 2018), and daime (Daims et al., 2006). .. Otsu's method for threshold selection, used by the COMSTAT implementations in MATLAB and ImageJ, maximizes the intra-class correlation (Otsu, 1979), where each class is composed of pixels with intensities either above or below the threshold.

Methods and Results: Lactobacillus isolates (L. plantarum G1, L. plantarum B1, L. brevis S1, and L. paracasei W1) in biofilm and planktonic cell suspensions were treated with chlorine-based (0∙018% and 0∙18%) and quaternary ammonium compounds (QACs)-based (0∙2% and 2∙0%) disinfectants for 5 min and then analyzed by plate counting, flow cytometry (FCM), and fluorescence activated cell sorting (FACS).. The reaction of sessile cells to disinfectants was assessed with the confocal laser scanning microscopy (CLSM).
