Rapid Discrimination of <i>Pseudomonas aeruginosa</i> ST175 Isolates Involved in a Nosocomial Outbreak Using MALDI-TOF Mass Spectrometry and FTIR Spectroscopy Coupled with Machine Learning

<div>Fourier-transform infrared spectroscopy spectra of <i>Pseudomonas aeruginosa</i> isolates in the lipids region after applying second derivative. (a) 1,400–1,500 cm<sup>−1</sup> region with different absorbance among outbreak and not-outbreak isolates (1,445 cm<sup>−1</sup>). (b) 2,800–3,000 cm<sup>−1</sup> region with different absorbance among outbreak and not-outbreak isolates (2,925 and 2,955 cm<sup>−1</sup>).</div>
