The ability of uropathogenic Escherichia coli isolates in biofilm formation on urinary catheter and association with bcsA and draE genes
The product biofilm by E.coli strain can cause serious problem for human health. Catheter is considered to be s suitable place for colonization of microorganisms, so that in %5-10 of patients who used catheter for only one day and also in all patients who used it for over 28 days, this colonization of bacteria is observed on catheter. This study is come out in order to compare biofilm formation...
متن کاملClonal relationships among bloodstream isolates of Escherichia coli.
The clonal relationships among 187 bloodstream isolates of Escherichia coli from 179 patients at Boston, Mass., Long Beach, Calif., and Nairobi, Kenya, were determined by multilocus enzyme electrophoresis (MLEE), analysis of polymorphisms associated with the ribosomal operon (ribotyping), and serotyping. MLEE based on 20 enzymes resolved 101 electrophoretic types (ETs), forming five clusters; r...
متن کاملEpidemiological correlates of virulence genotype and phylogenetic background among Escherichia coli blood isolates from adults with diverse-source bacteremia.
Associations of virulence genotype and phylogenetic background with epidemiological factors (primary source of bacteremia, host compromise status, and hospital versus community origin) were assessed among 182 Escherichia coli blood isolates from adults with diverse-source bacteremia in comparison with fecal controls from the E. coli Reference collection. A continuum of virulence was found, from...
متن کاملThe Bacterial Amyloid Curli Is Associated with Urinary Source Bloodstream Infection
Urinary tract infections are the most common cause of E. coli bloodstream infections (BSI) but the mechanism of bloodstream invasion is poorly understood. Some clinical isolates have been observed to shield themselves with extracellular amyloid fibers called curli at physiologic temperature. We hypothesize that curli fiber assembly at 37 °C promotes bacteremic progression by urinary E. coli str...
متن کاملIdentification of Factors Associated with Biofilm Formation Ability in the Clinical Isolates of Helicobacter pylori
Background: A few reports confirm the ability of Helicobacter pylori to form biofilm. However, conclusive data do not exist concerning the factors that favor this ability.Objectives: Evaluation of the factors associated with the biofilm formation ability of H. pylori including bacterial, physical and chemical, and environmental factors was the research’s aim.Materials and Methods: H...
