Identification of virulence factors among ESBLs-producing escherichia coli clinical isolates from Gaza strip, Palestine

This study was done to assess the occurrence of virulence factors and correlation of phylogenetic grouping in ESBLs producing E. coli isolates from Palestine. Twenty-seven ESBLs producing E. coli isolates were collected between April and June 2013 from three hospitals in Gaza. Detection of genes encoding virulence factors, pathogenicity associated island marker (PAI) and phylogenetic groups were studied by PCR. The correlation of E. coli phylogenetic grouping with the virulence factors in the isolates was studied.
