Identification of bacterial isolates
The identification of all bacterial isolates was performed by mass
spectrometry using the Matrix Assisted Laser Desorption/Ionization
(MALDI) mass spectrometer (Bruker Daltonics, MALDI Biotyper, Fremont,
CA, USA), a high-throughput proteomic technique for identification of a
variety of bacterial and fungal species (Sogawa K. et. al, 2011;
Ferrazzano G.F. et. al, 2017; Cicatiello A.G. et al, 2014). Through this
identification procedure a reliability threshold of 1.4 was established.
