Analysis of P. aeruginosa biofilm formation. ( A ) Surface coverage of P. aeruginosa ATCC 27853 during the biofilm formation step. ( B ) Representative bright-field microscopic images of various developmental stages of P. aeruginosa ATCC 27853 biofilms: initial attachment (0 h), strong adhesion (8 h), early developmental stage (microcolony formation—12 h), maturation (macrocolony formation—16, 24, and 48 h).

Techniques:

( A ) Biofilms of P. aeruginosa ATCC 27853 stained with SYBR Green I and PI before and after antibiotic treatment, as well as during the regrowth phase. Bottom: effect of PEN, CST, and DAR B on mature P. aeruginosa ATCC 27853 biofilms during the 3-h treatment ( B ) and during the regrowth phase ( C ). The ratio of membrane-compromised (red-stained) cells to total cells was calculated over time during the treatment and regrowth phases.

( A ) Representative microscopic images of P. aeruginosa ATCC 27853 biofilms stained with SYBR Green I and PI before and after treatment(s) with 64 µg/mL DAR B, as well as during the 48-h regrowth phase in the multidose experiments. Each treatment involved the application of 64 µg/mL DARB for 2 h with a 24-h interval. Bottom: effect of DAR B on mature P. aeruginosa ATCC 27853 biofilms during the sequential 2-h treatments ( B ) and the regrowth phase ( C ). The ratio of membrane-compromised (red-stained) cells to total cells and percentage of surface coverage were calculated over time during the treatment and regrowth phases (simplified; detailed calculations of each 2-h treatment are shown in ).
