A variety of virulence genes are associated with Escherichia coli mediated urinary tract infections. Particular sets of virulence factors shared by bacterial strains directing them through a particular pathogenesis process are called a "pathotype." Comparison of co-occurrence of potential urinary tract infection (UTI) virulence genes among different E. coli isolates from fecal and UTI collectio...

This study was intended to investigate the effectiveness of static magnetic field on the growth of Escherichia coli (E. coli) provided from two sources, the urine samples of patients with urinary tract infections and the reference strain E. coli ATCC 25922. Bacterial samples in Nutrient Broth were subjected to a range of magnetic intensities (2, 4, 6, 9, 14, 16, 18, and 20 mT) at various exposu...

Objective(s): Escherichia coli strains are common pathogens that can cause urinary tract infections (UTI). This study aimed to assess E. coli phylogroups and virulence types in male and female UTI patients.Materials and Methods: In the present study, 160 uropathogenic E. coli (UPEC) isolates (from both sexes) were assigned to phylogroups/types and some extraintestinal virulence factors were det...

There are many different bacterial infections in the world that patients are suffering from and research teams are trying to find suitable ways to prevent and treat them. Urinary Tract Infections (UTIs) are most important infections in the world , and they are more common among women because vaginal cavity is near to urethral opening. The aim of this study is cloning of synthetic gene include a...

Emergence of antimicrobial resistance amongst uropathogenic Escherichia coli and Klebsiella pneumoniae has become a major public health concern of the 21st century [1]. According to World Health Organization (WHO) report 2014, alarming rates of resistance have been reported in all WHO regions due to resistant pathogens like E. coli, K. pneumoniae and Staphylococcus saprophyticus causing urinary...

Carbon monoxide (CO) releasing molecules (CO-RMs) have been shown to inhibit growth of commensal Escherichia coli (E. coli). In the present study we examined the effect of CORM-2 on uropathogenic E. coli (UPEC) that produces extended-spectrum β-lactamase (ESBL). Viability experiments showed that CORM-2 inhibited the growth of several different ESBL-producing UPEC isolates and that 500 μM CORM-2...

The first step in the colonization of the human urinary tract by pathogenic Escherichia coli is the mannose-sensitive binding of FimH, the adhesin present at the tip of type 1 pili, to the bladder epithelium. We elucidated crystallographically the interactions of FimH with D-mannose. The unique site binding pocket occupied by D-mannose was probed using site-directed mutagenesis. All but one of ...
