Extended-Spectrum β-Lactamase-Producing Escherichia coli and Virulence Genes in Pediatric Patients with Health-Care Urinary Tract Infections.

The present study highlights the presence of virulence genes and bla gene in uropathogenic E. coli isolated from pediatric patients with healthcare-associated urinary tract infections. There was an association between the bla gene and virulence genes FimH, pap, sfa, Afa, and aer. Various distributions of the studied genes with a high frequency of fimbria are flic genes. Moreover, the ESBL had high frequency in E. coli with the presence of bla in about one-third of the isolates.
