Type 1 fimbriae, a colonization factor of uropathogenic Escherichia coli, are controlled by the metabolic sensor CRP-cAMP. [PDF]

PLoS Pathogens, 2009
Type 1 fimbriae are a crucial factor for the virulence of uropathogenic Escherichia coli during the first steps of infection by mediating adhesion to epithelial cells. They are also required for the consequent colonization of the tissues and for invasion

Sialic acid and N-acetylglucosamine Regulate type 1 Fimbriae Synthesis

Microbiology Spectrum, 2015
ABSTRACT Type 1 fimbriae of E. coli , a chaperon-usher bacterial adhesin, are synthesized by the majority of strains of the bacterium. Although frequently produced by commensal strains, the adhesin is nevertheless a virulence factor in Extraintestinal Pathogenic E. coli (ExPEC). The

Type 1 Fimbriae, Curli, and Antigen 43: Adhesion, Colonization, and Biofilm Formation

EcoSal Plus, 2004
This review is primarily concerned with the first step in biofilm formation, namely, bacterial attachment to surfaces. It describes three examples of bacterial adhesins, each of which belongs to a different subgroup and follows different strategies for surface presentation and adhesin exposure.

Role of the stress-responsive two-component system CpxAR in regulating fimbriae expression in Klebsiella pneumoniae CG43

Journal of Microbiology, Immunology and Infection, 2023
Background: CpxAR is a two-component system that allows bacteria to reorganize envelope structures in response to extracellular stimuli. CpxAR negatively affects type 1 fimbriae expression in Klebsiella pneumoniae CG43, a hypervirulent strain.

Type 1 fimbriae of Salmonella enteritidis [PDF]

Journal of Bacteriology, 1991
Salmonella enteritidis was previously shown to produce fimbriae composed of 14,000-molecular-weight (Mr) fimbrin monomers (J. Feutrier, W. W. Kay, and T. J. Trust, J. Bacteriol. 168:221-227, 1986). Another distinct fimbrial structure, comprising 21,000-Mr fimbrin monomers, has now been identified.

The role of urease in the acid stress response and fimbriae expression in Klebsiella pneumoniae CG43

Journal of Microbiology, Immunology and Infection, 2022
Background/purpose: Two urease operons were identified in Klebsiella pneumoniae CG43, ure-1 and ure-2. This study investigates whether a differential regulation of the expression of ure-1 and ure-2 exists and how urease activity influences the acid ...

Functional heterogeneity of type 1 fimbriae of Escherichia coli [PDF]

Infection and Immunity, 1992
Escherichia coli and other members of the family Enterobacteriaceae express surface fibrillar structures, fimbriae, that promote bacterial adhesion to host receptors. Type 1 fimbriae possess a lectinlike component, FimH, that is commonly thought to cause binding to mannose-containing oligosaccharides of host receptors.

Molecular Epidemiology of Plasmid-Mediated Types 1 and 3 Fimbriae Associated with Biofilm Formation in Multidrug Resistant Escherichia coli from Diseased Food Animals in Guangdong, China

Microbiology Spectrum, 2022
Types 1 and 3 fimbriae in Enterobacteriaceae play versatile roles in bacterial physiology including attachment, invasion, cell motility as well as with biofilm formation and urinary tract infections.

Antigens Of The Type-1 Fimbriae Of Salmonellae And Other Enterobacteria [PDF]

Journal of Medical Microbiology, 1969
Summary Antigens that determine agglutination reactions, and are distinct from the O-, H- and Vi-antigens, were demonstrated in the type-1 fimbriae of bacteria in fimbriate-phase cultures of salmonellae. Most strains of salmonellae produced fimbriate cultures when grown for a sufficient period, e.g., 24–48 hr, at 37°C in aerobic static broth.

Pseudocatabolite repression of type 1 fimbriae of Escherichia coli [PDF]

Journal of Bacteriology, 1982
Previous work on the control of fimbriation in bacteria has demonstrated the importance of environmental factors such as static versus shaking broth and the absence versus the presence of glucose on the degree of fimbriation. When the Pil+ K-12 strain of Escherichia coli CSH50 was grown in static broth, the bacteria grown with glucose were less ...
