Adhesion of Escherichia Coli to Nanostructured Surfaces and the Role of Type 1 Fimbriae [PDF]

Nanomaterials, 2020
Bacterial fimbriae are an important virulence factor mediating adhesion to both biotic and abiotic surfaces and facilitating biofilm formation. The expression of type 1 fimbriae of Escherichia coli is a key virulence factor for urinary tract infections ...

What Flips the Switch? Signals and Stress Regulating Extraintestinal Pathogenic Escherichia coli Type 1 Fimbriae (Pili) [PDF]

Microorganisms, 2021
Pathogens are exposed to a multitude of harmful conditions imposed by the environment of the host. Bacterial responses against these stresses are pivotal for successful host colonization and pathogenesis. In the case of many E.

Fimbriae reprogram host gene expression - Divergent effects of P and type 1 fimbriae. [PDF]

PLoS Pathogens, 2019
Pathogens rely on a complex virulence gene repertoire to successfully attack their hosts. We were therefore surprised to find that a single fimbrial gene reconstitution can return the virulence-attenuated commensal strain Escherichia coli 83972 to ...

Surface Display of Type 1 Fimbriae on Shigella flexneri Induces Antigen-Specific Immune Response via Oral Route [PDF]

Vaccines
Background: Live attenuated bacteria are promising candidates for mucosal vaccine delivery due to their ability to elicit robust immune responses. FimH is the adhesion protein of type 1 fimbriae, which is used as mucosal adjuvants.

Role of type 1 and type 3 fimbriae in Klebsiella pneumoniae biofilm formation [PDF]

BMC Microbiology, 2010
Background Klebsiella pneumoniae is an important gram-negative opportunistic pathogen causing primarily urinary tract infections, respiratory infections, and bacteraemia. The ability of bacteria to form biofilms on medical devices, e.g.

Type 1 fimbriae-mediated collective protection against type 6 secretion system attacks [PDF]

mBio
Bacterial competition may rely on secretion systems such as the type 6 secretion system (T6SS), which punctures and releases toxic molecules into neighboring cells.

yqhG Contributes to Oxidative Stress Resistance and Virulence of Uropathogenic Escherichia coli and Identification of Other Genes Altering Expression of Type 1 Fimbriae [PDF]

Frontiers in Cellular and Infection Microbiology, 2019
Urinary tract infections (UTIs) are common bacterial infections and the vast majority of UTIs are caused by extraintestinal pathogenic Escherichia coli (ExPEC) strains referred to as uropathogenic E. coli (UPEC).

Demonstration of regulatory cross-talk between P fimbriae and type 1 fimbriae in uropathogenic Escherichia coli [PDF]

Microbiology, 2006
The majority ofEscherichia colistrains isolated from urinary tract infections have the potential to express multiple fimbriae. Two of the most common fimbrial adhesins are type 1 fimbriae and pyelonephritis-associated pili (Pap). Previous research has shown that induced, plasmid-based expression of a Pap regulator,papB, and its close homologues can ...

Purification and Characterization of Type 1 Fimbriae of Salmonella typhi [PDF]

Microbiology and Immunology, 1994
AbstractType 1 fimbriae have been purified from a Salmonella typhi strain of clinical origin. Purified fimbriae retained their ability to bind to erythrocytes in a mannose‐inhibitable fashion and, in doing so, behaved preferentially as a monovalent adhesin.

Actinomyces Adsorption Mediated by Type-1 Fimbriae

Journal of Dental Research, 1986
Monospecific antibody against the type-1 fimbriae of Actinomyces viscosus T14V reacted with 12 strains of A. viscosus (serotype 2), 12 strains of A. naeslundii (serotype 2 or serotype 3), but not with 11 serotype 1 strains of A. naeslundii. All strains positive for the type-1 fimbrial antigen adsorbed strongly to saliva-treated hydroxyapatite, and in ...
