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.

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 ...

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,

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).

Transcriptional organization of the Escherichia coli pilus adhesin K99
Molecular Microbiology, 1993SummaryThe production of the Escherichia coli pilus adhesin K99 requires the expression of eight unique proteins: FanA‐H. The transcriptional organization of the K99 operon was investigated by Northern blot analysis. Four RNAs of 0.54, 1.4, 2.5 and 3.5kb were detected.

Glycolipid Receptors of F1C Fimbrial Adhesin of Uropathogenic Escherichia coli
2005The ability of F1C fimbriated bacteria to bind to the human urinary tract could be demonstrated by performing binding studies using several different cell lines as shown in table 1, and by performing direct binding assay using human bladder epithelial cell line RT112 as shown in Fig 1.

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

Anti-Escherichia Coli Adhesin Activity of Cranberry and Blueberry Juices
1996For many decades, cranberry juice has been recommended by physicians in North America for the treatment or prevention of urinary tract infections (UTI). However, until recently, no experimental evidence has been presented for the purported beneficiary effect of the juice, nor for its mechanism of action.

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

Adhesins of EnterotoxigenicEscherichia coliStrains That Infect Animals
EcoSal Plus, 2005The first described adhesive antigen ofEscherichia colistrains isolated from animals was the K88 antigen, expressed by strains from diarrheic pigs. The K88 antigen was visible by electron microscopy as a surface-exposed filament that was thin and flexible and had hemagglutinating properties.
