Differential Afa/Dr Fimbriae Expression in the Multidrug-Resistant Escherichia coli ST131 Clone

mBio, 2022
Many antibiotic resistant uropathogenic Escherichia coli (UPEC) strains belong to clones defined by their multilocus sequence type (ST), with ST131 being the most dominant.

Identification of Coli Surface Antigen 23, a Novel Adhesin of Enterotoxigenic Escherichia coli [PDF]

Infection and Immunity, 2012
ABSTRACT Enterotoxigenic Escherichia coli (ETEC) is an important cause of diarrhea, mainly in developing countries. Although there are 25 different ETEC adhesins described in strains affecting humans, between 15% and 50% of the clinical isolates from different geographical regions are negative for these ...

Std fimbriae-fucose interaction increases Salmonella-induced intestinal inflammation and prolongs colonization [PDF]

, 2019
Author summary The intestinal epithelium is a crucial biological interface, interacting with both commensal and pathogenic microorganisms. It’s lined with heavily glycosylated proteins and glycolipids which can act as both attachment sites and energy ...

Asymptomatic bacteriuriaEscherichia colistrains: adhesins, growth and competition [PDF]

FEMS Microbiology Letters, 2006
Urinary tract infections (UTIs) affect millions of people each year. Escherichia coli is the most common organism associated with asymptomatic bacteriuria (ABU) in humans. Persons affected by ABU may carry a particular E. coli strain for extended periods of time without any symptoms. In contrast to uropathogenic E.

Phylogeny, Resistome, and Virulome of Escherichia coli Causing Biliary Tract Infections [PDF]

, 2019
Escherichia coli is the most frequent Gram-negative bacilli involved in intra-abdominal infections. However, despite high mortality rates associated with biliary tract infections due to E. coli, there is no study focusing on this pathogen. In this study,

Porcine intestinal glycosphingolipids recognized by F6-fimbriated enterotoxigenic Escherichia coli [PDF]

, 2014
One important virulence factor of enterotoxigenic Escherichia coli is their ability to adhere via fimbrial adhesins to specific receptors located on the intestinal mucosa. Here, the potential glycosphingolipid receptors of enterotoxigenic F6-fimbriated E.

Prospective study to compare antibiosis versus the association of N-acetylcysteine, D-mannose and morinda citrifolia fruit extract in preventing urinary tract infections in patients submitted to urodynamic investigation [PDF]

, 2017
BACKGROUND: The abuse of antimicrobical drugs has increased the resistance of microorganisms to treatments, thus to make urinary tract infections (UTIs) more difficult to eradicate.

Genotypic characterization of virulence factors in Escherichia coli strains from patients with cystitis Caracterização genotípica dos fatores de virulência em amostras de Escherichia coli isoladas de pacientes com cistite

Revista do Instituto de Medicina Tropical de São Paulo, 2008
Adhesins (P-fimbriae, S-fimbriae, type 1 fimbriae and afimbrial adhesin), toxins (α-hemolysin and cytotoxic necrotizing factor type 1), iron acquisition systems (aerobactin) and host defense avoidance mechanisms (capsule or lipopolysaccharide) have ...

Type III Secretion Effectors with Arginine N-Glycosyltransferase Activity [PDF]

, 2020
Type III secretion systems are used by many Gram-negative bacterial pathogens to inject proteins, known as effectors, into the cytosol of host cells. These virulence factors interfere with a diverse array of host signal transduction pathways and cellular

Structural Sampling of Glycan Interaction Profiles Reveals Mucosal Receptors for Fimbrial Adhesins of Enterotoxigenic Escherichia coli

Biology, 2013
Fimbriae are long, proteinaceous adhesion organelles expressed on the bacterial envelope, evolutionarily adapted by Escherichia coli strains for the colonization of epithelial linings. Using glycan arrays of the Consortium for Functional Glycomics (CFG),
