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>Classification of <i>Pseudomonas aeruginosa</i> strains as “outbreak” by pulse-field gel electrophoresis (PFGE) and “not outbreak” (in dark green). The three different groups obtained by whole-genome sequencing (WGS) are shown: Group 1, where the outbreak isolates are clustered; Group 2, containing two isolates separated by 30 single nucleotide polymorphisms (SNPs) from Group 1; and Group 3, where 4 isolates separated by 104 SNPs from Group 1 clustered. According to WGS, Groups 2 and 3 are not part of the outbreak.</div>
