Mann–Whitney U test p-values for modification of antibiotic MIC by virulence genes.

	Amikacin	Cefotaxime	Ceftazidime	Imipenem	Meropenem	Pip–Taz
rmpA	0.285	0.051	0.432	0.363	0.527	0.411
K2	0.158	0.002	0.919	0.102	0.588	0.001
entB	0.009	0.918	0.117	0.015	0.291	0.072
ybtS	0.572	0.006	0.722	0.340	0.502	0.067
allS	0.326	0.024	0.001	0.086	0.537	0.013

Values in bold represent a p < 0.05, below the null hypothesis value with α = 5%, which means a significant difference in MIC due to the presence of the virulence factor. Pip–Taz, piperacillin–tazobactam.
