چکیده
Background and Objectives: Nosocomial infections are acquired during hospital treatment or in a hospital environment. One such infective agent is Escherichia coli, and many virulence genes enable it to become pathogenic, causing damage to the host. This study aimed to identify some important virulence factors, including aer ،traT and PAI genes, typical of uropathogenic Escherichia coli (UPEC) in the isolates collected from fecal and urinary tract infected patients in a center in Iran by multiplex polymerase chain reaction (PCR) assay. Materials and Methods: In doing so, 75 isolates of E.coli from the urine of inpatients and 75 isolates from Commensal faecal without UTI and diarrhea were collected. Antibiotic susceptibility pattern for 14 antibiotics was done. The occurrence of three virulence genes among all the isolates was confirmed by multiplex PCR.Results: The prevalence rates of aer ،traT and PAI genes in the fecal isolates were 92%, 90.6% and 46.6%, respectively and the rates in urine isolates were 96%, 97.3% and 41.3%, respectively. Conclusion: Despite the high frequency of these genes in both populations, there was no statistical relationship between them. The most antibiotic resistance was found in AMP, CZ and SXT. These results indicate the effect of external environment (hospital setting) on host susceptibility (increase of infection) in the fecal E. coli isolates, so making the patient prone to sepsis.کلیدواژه ها

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.
کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
