papG alleles of Escherichia coli strains causing first-episode or recurrent acute cystitis in adult women.
The distribution of the three alleles of the P adhesin gene papG (classes I-III) was assessed among 74 Escherichia coli urine isolates from women with first-episode or recurrent cystitis, and papG genotype was compared with clinical origin, O serogroup, agglutination of Gal(alpha1-4)Gal-coated latex beads and human or sheep erythrocytes, and hemolysin production. The class-III-only papG genotyp...
متن کاملExtended virulence genotypes of Escherichia coli strains from patients with urosepsis in relation to phylogeny and host compromise.
Among 75 urosepsis isolates of Escherichia coli, 29 virulence factor (VF) genes were detected by use of a novel polymerase chain reaction (PCR) assay. Compared with probe hybridization, the PCR assay's specificity was 100% and sensitivity 97.1%. fyuA (yersiniabactin: overall prevalence, 93%), traT (serum resistance, 68%), and a pathogenicity-associated island marker (71%) occurred in most strai...
متن کاملHost Characteristics and Bacterial Traits Predict Experimental Virulence for Escherichia coli Bloodstream Isolates From Patients With Urosepsis
Background. Extraintestinal Escherichia coli infections are common, costly, and potentially serious. A better understanding of their pathogenesis is needed. Methods. Sixty-seven E coli bloodstream isolates from adults with urosepsis (Seattle, WA; 1980s) underwent extensive molecular characterization and virulence assessment in 2 infection models (murine subcutaneous sepsis and moth larval let...
متن کاملEscherichia coli host strains.
To successfully perform molecular genetic techniques it is essential to have a full understanding of the properties of the various Escherichia coli host strains commonly used for the propagation and manipulation of recombinant DNA. E. coli is an enteric rod-shaped Gram-negative bacterium with a circular genome of 4.6 Mb (1). It was originally chosen as a model system because of its ability to g...
متن کاملRole of the K1 Capsule, PapG II, and Afa Adhesins in Escherichia coli Infections Arising from the Urinary Tract
BACKGROUND: Escherichia coli is the major pathogen in many extraintestinal Gram-negative bacillus infections. Both E. coli virulence characteristics and host factors contribute to the development of E. coli bacteremia in urinary tract infection (UTI). The aim of this study was to examine the bacterial virulence characteristics in E. coli infections arising from the urinary tract. METHODS: A tot...
