Biorecognition of Escherichia coli K88 adhesin for glycated porcine albumin

International Journal of Biological Macromolecules, 2009
Escherichia 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, 2007
This 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, 1988
Escherichia 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

Transcriptional organization of the Escherichia coli pilus adhesin K99

Molecular Microbiology, 1993
SummaryThe 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

2005
The 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.

Anti-Escherichia Coli Adhesin Activity of Cranberry and Blueberry Juices

1996
For 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.

K88 Adhesins of Enterotoxigenic Escherichia Coli and their Porcine Enterocyte Receptors

1999
The three antigenic variants of the K88 fimbrial adhesin (K88ab, K88ac, and K88ad) of enterotoxigenic Escherichia coli (ETEC) each exhibit unique specificity with regard to their hemagglutination characteristics. The variants are also unique in the specificity of their binding to the brush borders of enterocytes isolated from pigs with different ...

Adhesins of EnterotoxigenicEscherichia coliStrains That Infect Animals

EcoSal Plus, 2005
The 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.

Role of fimbrial adhesins in the pathogenesis of Escherichia coli infections

Canadian Journal of Microbiology, 1992
Escherichia coli strains are able to cause intestinal (enteritis, diarrhoeal diseases) and extraintestinal (urinary tract infections, sepsis, meningitis) infections. Most pathogenic E. coli strains produce specific fimbrial adhesins, which represent essential colonization factors: intestinal E.
