Antibodies against the Ag2 fimbriae of Actinomyces viscosus T14V inhibit lactose-sensitive bacterial adherence [PDF]

Infection and Immunity, 1982
Monospecific antisera against the Ag1 and Ag2 fimbrial components of Actinomyces viscosus T14V were produced by immunizing rabbits with immune precipitates of each antigen harvested from crossed-immunoelectrophoresis plates. The Fab fragments prepared from these sera were used as specific reagents in immunoelectron microscopy to identify each fimbrial ...

The Oral‐Gut Axis: Bidirectional Interactions Between Microbiome and Diseases

Journal of Periodontal Research, EarlyView.
This study aims to summarize the mechanisms underlying ectopic colonization of the gut by oral pathobionts and the microbial and host factors that regulate this process. ABSTRACT Increased colonization of typically oral microorganisms is frequently observed in the gut mucosa or lumen of individuals with gastrointestinal disorders, including patients ...

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

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.

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

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).

Osteoporosis and Periodontitis: Two‐Way Epidemiological and Mechanistic Evidence

Journal of Periodontal Research, EarlyView.
This review investigates the main mechanistic pathways connecting local periodontitis to systemic osteoporosis. Seven interconnected mechanisms are identified. ABSTRACT Osteoporosis and periodontitis are highly prevalent, chronic inflammatory diseases that constitute a major global health burden.

Chimeric FimH adhesin of type 1 fimbriae: a bacterial surface display system for heterologous sequences [PDF]

Microbiology, 1995
The FimH adhesin of type 1 fimbriae has been tested as a display system for heterologous protein segments on the surface of Escherichia coli. This was carried out by introduction of restriction site handles (BglII sites) in two different positions in the fimH gene, followed by in-frame insertion of heterologous DNA segments encoding two reporter ...

Diverse Microbial Communities Assemble on Both Recalcitrant and Labile Carbon Sources

Environmental Microbiology, Volume 28, Issue 7, July 2026.
Taxonomically and functionally distinct communities assemble on cellulose and its monomer, glucose. Although single carbon sources were provided, high and comparable diversity was maintained in both environments, supported by extensive cross‐feeding and scavenging. However, glucose supported higher biomass than cellulose and selected generalists, while

Effective assembly of fimbriae in Escherichia coli depends on the translocation assembly module nanomachine [PDF]

, 2016
Outer membrane proteins are essential for Gram-negative bacteria to rapidly adapt to changes in their environment. Intricate remodelling of the outer membrane proteome is critical for bacterial pathogens to survive environmental changes, such as entry ...

Der Einfluss von P-Fimbrien auf eine Leukozyturie und den Schwellenwert einer persistierenden Bakteriurie [Effect of P fimbriae on pyuria and bacterial colonization of the human urinary tract]

, 2003
This study investigated the role of P fimbriae in colonization of Escherichia coli, host response, and bacterial persistence in humans. Human volunteers were inoculated intravesically with the nonadherent ABU isolate E.

Type 3 fimbriae of Klebsiella sp.: molecular characterization and role in bacterial adhesion to plant roots [PDF]

Journal of Bacteriology, 1983
Type 3 fimbriae of Klebsiella were purified and characterized. The fimbriae were 4 to 5 nm in diameter and 0.5 to 2 microns long. In sodium dodecyl sulfate-polyacrylamide gel electrophoresis, the fimbrillin had an apparent molecular weight of 23,500, and it differed from enterobacterial type 1 fimbrillins in its amino acid composition.
