Figure 1. Classification of strains as not-outbreak and outbreak, including the three different groups obtained by whole-genome sequencing.
Figure 2. Classification of MALDI-TOF MS spectra between outbreak and not outbreak isolates (A. Hierarchical Clustering Analysis; B. Principal Component Analysis), and C.Differentiation of WGS-groups by PLS-DA algorithm.
Figure 3. Dendrogram obtained by IR Biotyper for P. aeruginosa isolates analyzed in the lipids region (1400-1500 and 2800-3000 cm-1). ST, Sequence Type; PFGE, Pulsed-Field Gel Electrophoresis; WGS, Whole-Genome Sequencing.
Figure 4. Principal Component Analysis (PCA) scatter plot obtained by FTIR. A: Plot according to Sequence Type (ST) of isolates obtained by IR Biotyper software. B: Plot according to ST obtained by Clover MS Data Analysis software. C: Plot according to Whole-Genome Sequencing (WGS) outbreak groups obtained by IR Biotyper software. D: Plot according to WGS groups obtained by Clover MS Data Analysis software.
Figure 5. Fourier-Transform Infrared (FTIR) spectra of P. aeruginosa isolates in the lipids region. A: 1400-1500 cm-1 region with different absorbance among outbreak and not-outbreak isolates (1445 cm-1). B:2800-3000 cm-1 region with different absorbance among outbreak and not-outbreak isolates (2925 and 2955 cm-1).
