Dotted lines indicate the time points when major changes in antibiotic susceptibility occurred, which correspond to the three phases (I, II, and III) marked in panels A, B, and C. E. coli biofilms were formed on glass surfaces. The antibiotic susceptibility was tested in 0.85% NaCl solution (no carbon source) to minimize the effects of cell growth. At least five biological replicates were tested for each data point.

    Cells embedded in early-stage biofilms remained active and sensitive to antibiotics if dispersed prior to antibiotic treatment. (A) Representative fluorescence images of E. coli RP437, E. coli AR3110 (wild type), E. coli AR182 (ΔbscA), and E. coli AR282 (ΔcsgB) biofilms at different time points (1, 3, 16, and 24 h) during biofilm formation. The embedded cells were labeled with SYTO9, and the cellulose in the biofilm matrix was labeled with Congo red. (B and C) Susceptibility of different cell populations (detached biofilm cells and planktonic cells in the same static biofilm cultures) to Amp (B) or Ofx (C) during early events of biofilm formation. The susceptibility of planktonic cells was repeated (from Fig. 1A and ​andB)B) in these two panels as references for comparison. The antibiotic treatment was conducted in 0.85% NaCl solutions. (D) Representative fluorescence images of E. coli RP437 biofilms. Alexa Fluor 594-WGA stains sialic acid and N-acetyl-d-glucosamine in biofilm matrix, while SYTO9 stains surface-attached E. coli RP437 cells. E. coli RP437 biofilms were formed on glass surfaces in LB medium, and each condition was tested with three biological replicates (n = 3).

    A hypothetic model of antibiotic susceptibility during early-stage biofilm formation. Phases I, II, and III in this diagram are the main findings from this study. Cells with dotted lines in the cell membrane represent these initially attached cells or cells in interactions with increased membrane permeability. The mechanisms in biofilm maturation and dispersion are based on literature. They are included here to show the whole process of biofilm formation and associated antibiotic tolerance.
