Prevalence of virulence factors and phylogenetic characterization of uropathogenic Escherichia coli causing urinary tract infection in patients with and without diabetes mellitus.

Background: We aimed to determine the virulence factor profile and phylogenetic grouping of uropathogenic Escherichia coli (UPEC) causing urinary tract infection (UTI) in patients with and without diabetes mellitus (DM).

Methods: A total of 280 UPEC were collected from the urine samples of patients with DM (n=126) and patients suffering from non-DM UTIs (n=154). All isolates were subjected to phenotypic and genotypic virulence factor profile and phylogenetic grouping.
