Introduction: Urinary tract infection (UTI) caused by E coli is one of the most common diseases in community. Colonization of E. coli and its attachment to the uroepithelium are mediated by adhesions such as P, Fim and S fimbriae. The present study was aimed to evaluate the prevalence of fimbrial virulence genes in Escherichia coli (E. coli) isolates from the patients with urinary tra...

Background: Iron adsorption factors are among the most important virulence factors of P. mirabilis causing urinary tract infections. The aim of the present study was the evaluation of the frequency and nucleotide sequence of genes encoding the iron adsorption genes in Proteus mirabilis isolated from patients with urinary tract infections. Materials and Methods: In total, 100 P. mirabilis isola...

Background : Urinary tract infection (UTI) is a common health problem among children that may lead to irreversible renal injuries. The aim of the present study was to determine the association between the delay in treatment of urinary tract infection and risk of renal damage Materials and methods : For this retrospective study 100 children aged 1 month to 14 years who were admitted with urinary...

Background & Objectives: Urinary tract infection is a common disease, especially among women. Beta-lactam group of antibiotics are the commonly prescribed antibiotics for this disorder. The emergence of antibiotic resistance among gramnegative bacilli limited applicability and usefulness of the antibiotics. In this study, we assessed the prevalence of extended spectrum beta-lactamases (ESBL) pr...

Background & Aim: Antibiotic resistance to quinolones as a therapeutic agent of urinary tract infection in increasing in the world. Thus, this study was designed to evaluate the resistance to quinolone antibiotics in Escherichia coli isolated from urinary tract infection of hospitalized patients in Tehran, Iran in 2017. Methods: In the present study, 150 E. coli isolates was collected from uri...
