Polymorphonuclear Leukocytes or Hydrogen Peroxide Enhance Biofilm Development of Mucoid Pseudomonas aeruginosa

Figure 6

Effect of PMNs on biofilms of mucoid P. aeruginosa FRD1. Confocal laser scanning micrographs of P. aeruginosa FRD1 biofilms treated with PMNs. (a) Control group, early biofilm treated without PMNs. (b) Early biofilm treated with PMNs. (c) Mature biofilm treated without PMNs. (d) Mature biofilm treated with PMNs. Cells staining red are considered dead while cells staining green are viable cells.
