a
Whole-genome sequencing (WGS) was performed.
b
Non-MI, non-motility induction.
c
MI, motility induction.
d
WGS produced the same results as serotyping but not MALDI-TOF.
e
WGS produced the same results as MALDI-TOF but not serotyping.
f
WGS produced different results than both serotyping and MALDI-TOF.
