  Acute pyelonephritis (APN) as one of the most severe form of UTIs may result in significant morbidity. We aim to investigate the antimicrobial susceptibilities and genetic traits of Escherichia coli isolates associated with APN. Totally, 64 APN E. coli isolates were analyzed for the antimicrobial susceptibilities, phylogenetic groups, resistance and virulence determinants, plasmid replicons, pulsed-field gel electrophoresis (PFGE), and Multi-locus sequence types (MLST). High percentages of resistance (>65.0%) to ampicillin/sulbactam and levofloxacin were observed, imipenem and fosfomycin displayed good in vitro sensitivity (>93.0%). Most of the strains belonged to phylogenetic group D (50.6%) and B2 (21.6%), D strains were more resistant than B2 ones towards the cephalosporins tested (p0.05). Thirty-six (56.3%) blaCTX-M, 3 (4.7%) rmtB, and 13 plasmid mediated.. View More»
