Revelation of Specific Ferocity Genes in Escherichia coli Isolated from Patient with Urinary Tract Infections (UTIs)

Abstract

Background:  The purpose of this research is to detect the occurrence of ferocity genes in uropathogenic E. coli that isolated from urinary tract infections by Polymerase chain reaction technique.  Method: A whole of five strains of E.coli were obtained from patient with urinary tract infections. Identification of E.coli was depended on colonial morphology in culture media, gram stain, and conventional biochemical tests.  ferocity factors genes (cnf-1, hly,urea A and ndv B) of E.coli strain were revelated by molecular technique. Results: ferocity genes were detected successfully by molecular technique in five isolates of E.coli, the predominance of  genes in isolates are seen in percentage    100% Conclusion: Urinary tract infections still the major universal infection in the worldwide. The one of the most prevalent infectious diseases induce renal failure in patients is UTI that generated by UPEC. The presence of ferocity factors are critical features where the grade of pathogenicity of UPEC strains relied on it. This study indicate that was a real relationship between the ferocity factor genes of E.coli  and clinical symptoms of UTI.
