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

Figure 9

Effect of PMNs on GMD activity. GMD: GDP-mannose dehydrogenase; Control: P. aeruginosa FRD1 biofilm grown for 24 hours or 48 hours without PMNs; PMN: P. aeruginosa FRD1 biofilm treated with PMNs for 24 hours or 48 hours. Activities of GMD in FRD1 biofilms treated with PMNs were significantly different from those in FRD1 biofilms without PMNs. Data are presented as the means ± SD ( in each treatment). compared to the control group.
