Figure 3From: Comparison of disc diffusion, Etest and broth microdilution for testing susceptibility of carbapenem-resistant P. aeruginosa to polymyxinsComparative results between broth microdilution MICs and 300 U disc zone diameters for Polymyxin B (PB) tested against 78 carbapenem-resistant P. aeruginosa isolates. The broken lines represent the breakpoint values for Polymyxin B by disc diffusion method [10].Back to article page
