Detection of Some Virulence Genes of Uropathogenic Escherichia coli

Urinary tract infection is an infection involving part or all of the urinary tract which remains a common and troublesome health problem in many different countries all round the world. In most hospitals, very large numbers of UTIs were recorded daily among different ages and sexes. These infection may involve the urethra, bladder, ureters, the kidneys and prostates, the effect of infection depends on the interaction between the bacteria and host's defense mechanisms.The most important causes of UTIs represented by Gram negative bacteria belong to Enterobacteriacae family specially Escherichia coli. Although E.coli is a major component of the normal intestinal flora, but it is recognized as very active opportunistic pathogen associated with UTIs, because E.coli has several virulence factors which contribute to E.coli pathogenicity. The distribution of virulence factors can also vary depending on host characteristic and type of infection
