- W4282000812 abstract "Abstract Objectives Uropathogenic Escherichia coli (UPEC) strains are the most common cause of urinary tract infection (UTI) in hospitalized and community patients. The aim was to compare the genetic characteristics of E. coli isolated from inpatients (IPs) and outpatients (OPs) with UTI regarding their phylogenies, virulence traits, and resistance trends. Methods In this cross sectional study, a total of 130 unrelated E. coli isolates were collected from patients with UTI. Extended spectrum beta lactamase (ESBL) production was detected by combination disk method. Detection of UPEC and intestinal pathogenic E. coli (IPEC) virulence genes were performed by polymerase chain reaction. The isolates were analyzed for phylogenetic grouping. Results Out of the 130 isolates, 62.3% were from the OPs and 37.7% from the IPs. About 35.8% of the OPs and 49% of the IPs were ESBL positive. Moreover, 56.8% of the OPs and 59.2% of the IPs were positive for the UPEC virulence genes. Notably, 50% of the isolates from each group exhibited IPEC virulence properties. The predominant phylogroup was B2 (43.2% in the OPs and 40.8% in the IPs). No significant differences were found between the IP and OP isolates (P > 0.05). Conclusion The marked genetic plasticity of E. coli has allowed the emergence of strains showing arrays of genes from different pathotypes. Our results may indicate that consideration should also be given to hygienic standard in the community. Characterization of local E. coli isolates in different areas can guide the selection of effective infection control strategies." @default.
