Adhesins of Escherichia coli

Acta Biotechnologica, 1990
AbstractE. coli has got increasing importance as a causative agent of intestinal and extra‐intestinal diseases. In both these infections adhesion of the bacteria to mucous surface cells are initial events for coionization and development of infection. Adhesins are bacterial recognition proteins which specifically interact with carbohydrate moieties of ...

Fimbrial adhesins from extraintestinal Escherichia coli

Environmental Microbiology Reports, 2010
Summary Extraintestinal pathogenic Escherichia coli (ExPEC) represent an important subclass of E. coli that cause a wide spectrum of diseases in human and animal hosts. Fimbriae are key virulence factors of ExPEC strains.

Adhesins of Enteropathogenic Escherichia coli

EcoSal Plus, 2006
Enteropathogenic Escherichia coli (EPEC) strains induce morphological changes in infected epithelial cells. The resulting attaching and effacing (A/E) lesion is characterized by intimate bacterial adherence to epithelial cells, with microvillus destruction, cytoskeletal rearrangement, and aggregation of host ...

Characterisation of Escherichia coli fimbrial and autotransporter adhesins

2022
Escherichia 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, 2001
A 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, 1985
Fimbriae 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, 2005
Epidemiological 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

1992
The 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

1985
The 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.
