Table 1.

Concordance of MALDI-TOF speciation vs WGS for both clinical and environmental isolates. All non-concordant samples were either of the C. freundii or E. cloacae complex

	Clinical isolates	Environmental isolates	Combined clinical and environmental isolates
C. freundii/portucalensis	0/1 (0%)	16/21 (76%)	16/22 (73%)
E. cloacae/hormaechei	0/5 (0%)	3/8 (38%)	3/12 (25%)
E. coli	9/9 (100%)	11/11 (100%)	21/21 (100%)
K. pneumoniae	10/10 (100%)	8/8 (100%)	20/20 (100%)

Note that 48/60 environmental isolates are included in this table, the rest were different species. The numerator is the number of isolates that were concordant, the denominator is the number of total isolates of that species
