Effects of Lysozyme, Proteinase K, and Cephalosporins on Biofilm Formation by Clinical Isolates of Pseudomonas aeruginosa

Figure 3

Effect of lysozyme (30 μg/mL) and 50 times MIC of ceftazidime or cefepime alone or in combinations on the average reduction in percent biofilm mass of P. aeruginosa clinical isolates. The percent reduction in biofilm mass for each isolate was normalized to that for the control, which was free from the enzyme and antibiotics (set as 100% biofilm formation).
