Identification of novel DNA sequence associated with pathogenicity island III536 locus in Uropathogenic Escherichia coli isolate and distribution of virulence determinants in β-lactam resistant isolates

The current study investigated the prevalence of the ESBLs and virulence markers among different extraintestinal pathogenic E. coli. The findings of the study concur with previous investigations in regards to the presence of certain virulence determinants (PAI ICFT073, PAI IICFT073 and PAI IV536); found in multi-drug resistant clones such as ST131. A novel DNA fragment (597 bases) was identified, and the full sequence of the site is being investigated to retrieve the mosaic structure of the island.
