a—matrix-assisted laser desorption ionization time-of-flight mass spectrometry performed; b—results analyzed by SARAMIS Premium software v. 4.0.0.14, only strains with a percentage ≥ 75% similarity were considered identified; c—results analyzed by MBT Compass software. Data interpretation was done in line with Bruker’s standard criteria; a species cut-off score value of 2.0 and a genus cut-off score value of 1.7 were applied; d—intensive care unit; e—patient with co-infection with severe acute respiratory syndrome coronavirus 2; f—Hospital Infection Prevention and Control Committee; g—medical clinic.
