Comparative prevalence of virulence factors in Escherichia coli causing urinary tract infection in male infants with and without bacteremia.

چکیده
Escherichia coli isolates causing urinary tract infection in 83 male infants younger than 90 days with and without bacteremia were compared for phylogenetic groups and the presence of 10 virulence factors. Our result suggest that the absence of both hemolysin and antigen K1 may be used as a negative predictive factor for bacteremia.

Abstract Background and Objective: Urinary tract infection refers to the presence of microbial pathogens in the urinary tract and is one of the most common infections in outpatient and hospitalized patients. A wide variety of extra-intestinal infections in humans and animals are caused by the extracellular strains of Escherichia coli (EXPEC). Materials and methods: A total of 50 E. coli iso...

Background & Aim: Important challenge for treatment of urinary tract infections is the spread of extended-spectrum beta-lactamases (ESBLs) producing Escherichia coli. Therefore, the frequencies of main beta-lactamase genes, resistance to beta-lactams and the ability of ESBLs production in urinary and fecal Escherichia coli of women with urinary tract infections were compared. Methods: In 60 Es...
