Characterisation of Escherichia coli fimbrial and autotransporter adhesins
2022Escherichia coli is a Gram-negative bacterium that exhibits extensive diversity, ranging from a harmless commensal to a pathogen capable of causing serious intestinal and extra-intestinal infections. One feature that drives differences between commensal and pathogenic strains is the capacity to adhere to and colonise surfaces and form biofilms.

Characterization of a Galactose Specific Adhesin of Enteroaggregative Escherichia coli
Archives of Biochemistry and Biophysics, 2001A fimbrial adhesin was identified from an enteroaggregative Escherichia coli strain. The adhesin was purified to 740-fold by sequential chromatography on an affinity matrix and gel filtration column in the FPLC system. The homogeneity of the purified protein was established by analytical isoelectrofocussing (pI 7.25).

Fimbrial Adhesins of Escherichia coli
Clinical Infectious Diseases, 1985Fimbriae are long, threadlike protein polymers found on the surface of many strains of Escherichia coli. The presence of fimbriae has been found to be significantly correlated with pathogenicity, and specific fimbriae confer on pathogenic strains the ability to adhere to and colonize various specific host epithelia.

Adhesins of Diffusely Adherent and Enteroaggregative Escherichia coli
EcoSal Plus, 2005Epidemiological studies have implicated enteroaggregative Escherichia coli (EAEC) strains in acute and persistent diarrhea in children, in food-borne diarrhea outbreaks, and in traveler's diarrhea, and this group is recognized as an emerging pathotype of enteric disease. Diffusely adherent E. coli

Function and Organization of Escherichia Coli Adhesins
1992The adhesion of pathogenic bacteria to the epithelial surfaces of a host is a prelude to infection, followed by multiplication of the bacteria and their penetration into the host’s cells or their damaging of the epithelium by the action of their toxins. Adhesion is mediated by interaction between bacterial recognition proteins (adhesins, hemagglutinins,

Genes Determining Adhesin Formation in Uropathogenic Escherichia coli
1985The ability to adhere to the site of infection is considered to be a prerequisite for most bacterial infections. For a number of gram-negative species there is evidence that filamentous surface structures on the bacteria, called pili or fimbriae, are the adhesins that bind to epithelial cells of the host.

Biorecognition of Escherichia coli K88 adhesin for glycated porcine albumin
International Journal of Biological Macromolecules, 2009Escherichia coli (E. coli) that expresses galactose-reactive lectins, like K88 adhesin, causes high mortality among piglets. Carbohydrates that compete for adhesion could serve as an alternative for disease prevention. Porcine serum albumin (PSA) was modified by non-enzymatic glycation with lactose to produce PSA-Lac or PSA-Glc beta (1-4) Gal, as ...

A two-plasmid Escherichia coli system for expression of Dr adhesins
Protein Expression and Purification, 2007This paper presents a very efficient expression system for production of Dr adhesins. The system consists of two plasmids. One is the pACYCpBAD-DraC-C-His, which contains the draC gene under the control of the arabinose promoter (pBAD), encoding the DraC usher. The second is the pET30b-syg-DraBE, which contains the draB and draE genes under the control

Role of Escherichia Coli Adhesins in Urethral Colonization of Catheterized Patients
Journal of Urology, 1988Escherichia coli is a major cause of catheter-associated urinary tract infection and frequently colonizes the urethra prior to invading the urinary tract. Bacterial pili, filamentous protein cell surface-associated appendages, have been shown to mediate colonization of epithelial cells. Pili associated adhesins can be detected in vitro by their ability
