Long Polar Fimbriae of Enterohemorrhagic Escherichia coli O157:H7 Bind to Extracellular Matrix Proteins [PDF]

Infection and Immunity, 2011
ABSTRACT Adherence to intestinal cells is a key process in infection caused by enterohemorrhagic Escherichia coli (EHEC). Several adhesion factors that mediate the binding of EHEC to intestinal cells have been described, but the receptors involved in their recognition are not fully characterized ...

<i>Porphyromonas gingivalis</i> Bundled Fimbriae Interact with Outer Membrane Vesicles, Commensals and Fibroblasts. [PDF]

Int J Mol Sci
Porphyromonas gingivalis plays a key role in periodontal disease and has been associated with several serious systemic diseases. Its fimbriae are a major virulence factor.

Aggregative adherence fimbriae form compact structures as seen by SAXS [PDF]

, 2023
Bacterial colonization is mediated by fimbriae, which are thin hair-like appendages dispersed from the bacterial surface. The aggregative adherence fimbriae from enteroaggregative E. coli are secreted through the outer membrane and consist of polymerized

A study of the invasion and the cellular response of an in vitro 3D oral mucosal model by Porphyromonas gingivalis [PDF]

, 2012
Periodontitis is a leading cause of tooth loss worldwide. The Gram-negative anaerobe, Porphyromonas gingivalis, has been implicated in the initiation and cyclical progression of this inflammatory disease, which may be associated with its ability to ...

TLR2 activation by Porphyromonas gingivalis requires both PPAD activity and fimbriae [PDF]

, 2022
Porphyromonas gingivalis, a keystone oral pathogen implicated in development and progression of periodontitis, may also contribute to the pathogenicity of diseases such as arthritis, atherosclerosis, and Alzheimer's. P. gingivalis is a master manipulator

Regulation of poly-GlcNAc expression and fimbriation in uropathogenic "E. coli" [PDF]

, 2013
The transition of planktonic to sessile lifestyles in bacteria rests upon a tightly controlled program that gets triggered by the environmental composition and whose implementation requires multiple feedback controls. Uropathogenic E.

Application of MLST and Pilus gene sequence comparisons to investigate the population structures of Actinomyces naeslundii and Actinomyces oris [PDF]

, 2011
Actinomyces naeslundii and Actinomyces oris are members of the oral biofilm. Their identification using 16S rRNA sequencing is problematic and better achieved by comparison of metG partial sequences. A.

Specific interactions betweenPorphyromonas gingivalisfimbriae and human extracellular matrix proteins [PDF]

FEMS Microbiology Letters, 1999
The interactions of the extracellular matrix (ECM) proteins (laminin, elastin, fibronectin, type I collagen, thrombospondin and vitronectin) with the fimbriae of Porphyromonas gingivalis were analyzed based on surface plasmon resonance (SPR) spectroscopy using a biomolecular interaction analyzing system (BIAcore). The BIAcore profiles demonstrated that

Modes of evolution in a parasite?host interaction: Dis-entangling factors determining the evolution of regulated fimbriation in E. coli [PDF]

, 2008
Escherichia coli expresses type-I fimbriae; these are protrusions from the outer cell wall and have been identified as a virulence factor. They are also expressed by commensal strains of E.

Spikes and fimbriae: alpha-helical proteins form surface projections on microorganisms. [PDF]

Proceedings of the National Academy of Sciences, 1981
Two basic alpha-helical plans appear to characterize portions of the proteins projecting from the surface of many microorganisms. Structure A is related to that of the antibody-binding protein A of Staphylococcus aureus, in which a single polypeptide chain doubles back to form an Anti-parallel domain; the other, structure M, is related to the M ...
