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

Figure 2

Effect of nonactivated PMNs on viable cells of biofilms of mucoid P. aeruginosa FRD1. The numbers of viable cells in biofilms treated with PMNs are expressed in colony-forming units (CFUs). The error bars indicate standard deviations. BF: biofilm without PMNs; BF + nonactivated PMNs: biofilm treated with nonactivated PMNs. Data are presented as the mean ± SD ( in each treatment).
