Uropathogens from diabetic patients in Libya: virulence factors and phylogenetic groups of Escherichia coli isolates.

Urinary tract infections (UTIs) in patients with diabetes mellitus (DM) are reported mainly from developed countries. In addition to this underreporting from developing countries, there is a lack of information pertaining to the virulence factors (VFs) and phylogenetic grouping of uropathogenic Escherichia coli (UPEC) from DM and non-DM patients in developing countries. Between July 2005 and June 2006, urine specimens were collected from 135 DM and 164 non-DM patients, all with clinically diagnosed UTIs, attending Elkhadra Hospital and the Diabetic Center in Tripoli, Libya.
