3.1 MALDI-TOF MS analysis
All strains analyzed in this study (n=67) were identified by MALDI-TOF MS as P. aeruginosa with a score ≥2.0, showing, therefore, correct species-level identification according to the manufacturer’s criteria (Oviano & Rodriguez-Sanchez, 2021). Besides, this identification was the only one provided by MALDI-TOF MS along the top 10 identifications given for each isolate.
