Figure 4.
Representative mass spectra of peaks m/z 2,726, 5,455 and 5,742 in P. aeruginosa. Three peaks m/z 2,726, 5,455, and 5,742 were present in the majority of non-MDR isolates (green line) and at higher intensities than those in MDR isolates (red line). The average spectrum of each group of peaks m/z 2,726 (a), 5,455 (c), and 5,742 (e) and the spectra of all the analysed isolates for peaks m/z 2,726 (b), 5,455 (d), and 5,742 (f) are shown.
