IREB2 and bacterial urinary tract infection: Subgroup A1 showed 10 different PFtypes (pulse field types), where the PFtype comprises four strains (41, 48, 84, and 154) isolated from patients with community infections (UTI (n = 2) and respiratory infection (n = 1)), and hospital infections (pneumonia (n = 1)) showed different expression profiles of virulence genes associated with the antibiotic resistance genotype, with strain 84 showing the broadest profile (mrkD/ycfM/rpmA/entB/irp-1/irp-2/fyuA/iutA/hlyA/aac(3)-IV/blaSHV/tetA/blaCTXM-1/blaTEM).
