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 ...

MecVax supplemented with CFA MEFA-II induces functional antibodies against 12 adhesins (CFA/I, CS1–CS7, CS12, CS14, CS17, and CS21) and 2 toxins (STa, LT) of enterotoxigenic Escherichia coli (ETEC)

Microbiology Spectrum
Enterotoxigenic Escherichia coli (ETEC) strains that produce various adhesins and one or two enterotoxins are the leading causes of children’s diarrhea and travelers’ diarrhea.

Crystal Structure and Mutational Analysis of the DaaE Adhesin of Escherichia coli [PDF]

Journal of Biological Chemistry, 2006
DaaE is a member of the Dr adhesin family of Escherichia coli, members of which are associated with diarrhea and urinary tract infections. A receptor for Dr adhesins is the cell surface protein, decay-accelerating factor (DAF). We have carried out a functional analysis of Dr adhesins, as well as mutagenesis and crystallographic studies of DaaE, to ...

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),

Attaching and effacing Escherichia coli downregulate DNA mismatch repair protein in vitro and are associated with colorectal adenocarcinomas in humans [PDF]

, 2009
Background: Mucosa-associated Escherichia coli are frequently found in the colonic mucosa of patients with colorectal adenocarcinoma, but rarely in healthy controls. Chronic mucosal E. coli infection has therefore been linked to colonic tumourigenesis. E.

Identification of Potential Vaccine Strains of Escherichia coli Isolates From Diarrhoeic Calves. [PDF]

Vet Med Sci
This study aimed to identify vaccine candidate Escherichia coli strains isolated from diarrheic calves. Faecal samples collected from 500 calves were analysed, and E. coli strains were isolated and characterized phenotypically and genotypically. Antibiotic resistance profiles, virulence‐associated genes and MLVA genotyping were used to select 20 ...

Engineering Microbial Particles for Next‐Generation Biomedical Platforms

Advanced Science, EarlyView.
Microbe‐derived particles (MDPs), which include extracellular vesicles, outer membrane vesicles, inclusion bodies, polysaccharide particles, and virus‐like particles, represent a rapidly expanding category of bioinspired nanomaterials. With their natural origin, intrinsic biocompatibility, and highly programmable functionality, MDPs serve as a ...
