Virulence characteristics and antimicrobial susceptibility of uropathogenic Escherichia coli strains.
Eight virulence factors associated with uropathogenic Escherichia coli (UPEC) were investigated in 204 clinical isolates of E. coli recovered from urine cultures at counts ≥10(5). The bacteria were classified into two groups according to the number of leukocytes in urine samples from which they were isolated: group I ≤8 leukocytes/hpf, 104 strains; group II >8 leukocytes/hpf, 100 strains....
متن کاملMolecular Characterization and Antimicrobial Resistance of Uropathogenic Escherichia coli
Background:Urinary Tract Infections (UTIs) are the most common infectious diseases in childhood. The Uropathogenic Escherichia coli (UPEC) strains account for as much as 80% of UTIs. Objective:From a clinical perspective, it is important to know which virulence factors and antibiotic resistance properties are present in UPEC strains in pediatrics. Therefore, this study was carried out...
متن کاملBiological and genetic characteristics of uropathogenic Escherichia coli strains.
The aim of the present study was to determine biological characteristics such as expression of fimbriae, Congo red binding, production of hemolysin and aerobactin, adhesion to HeLa and uroepithelial cells and invasion of HeLa cells by Escherichia coli isolates obtained from patients showing clinical signs of urinary tract infection (UTI). Also, the presence of genes (apa, afa, spa) for fimbria ...
متن کاملPrevalence and persistence of Escherichia coli strains with uropathogenic virulence characteristics in sewage treatment plants.
We investigated the prevalence and persistence of Escherichia coli strains in four sewage treatment plants (STPs) in a subtropical region of Queensland, Australia. In all, 264 E. coli strains were typed using a high-resolution biochemical fingerprinting method and grouped into either a single or a common biochemical phenotype (S-BPT and C-BPT, respectively). These strains were also tested for t...
