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 ...

A general procedure for small-scale purification of fimbriae expressed by porcine enterotoxigenic Escherichia coli strains

Revista Colombiana de Biotecnología, 2008
Fimbriae expression by enterotoxigenic Escherichia coli strains is a complex process which is controlled by global and local transcriptional regulators and post-transcriptional control.

Periodontitis and Rheumatoid Arthritis—Mechanistic Evidence

Journal of Periodontal Research, EarlyView.
Periodontitis and rheumatoid arthritis are linked via the two‐hit model whereby early periodontal inflammation can lead to autoantibody production capable of interacting with inflamed synovial tissues. Subsequent systemic inflammation can exacerbate the periodontal inflammatory response and bacterial dysbiosis leading to further autoantibody production

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 ...

Design and Immunogenicity of a Nanoparticle Combination Vaccine for Salmonella in Poultry

Plant Biotechnology Journal, EarlyView.
ABSTRACT Salmonella enterica serovars (Salmonella) are common causes of bacterial gastroenteritis (salmonellosis) often associated with the consumption of poultry products. The control of Salmonella in broiler chickens is difficult because colonized birds may carry this pathogen undetected into the slaughterhouse and cause meat contamination.

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.

Difference in the regulation of IL-8 expression induced by uropathogenic E. coli between two kinds of urinary tract epithelial cells

Journal of Biomedical Science, 2009
Bacterial adherence to epithelial cells is a key virulence trait of pathogenic bacteria. The type 1 fimbriae and the P-fimbriae of uropathogenic Escherichia coli (UPEC) have both been described to be important for the establishment of urinary tract ...

Periodontitis and metabolic dysfunction‐associated steatotic liver disease

Periodontology 2000, EarlyView.
Abstract Objective Periodontitis is a chronic inflammatory disease with systemic effects that extend beyond the oral cavity and contribute to systemic immune and metabolic dysregulation. Chronic liver diseases, particularly metabolic dysfunction‐associated steatotic liver disease (MASLD) and its progressive phenotypes, have emerged as major global ...

Molecular analysis of type 3 fimbrial genes from Escherichia coli, Klebsiella and Citrobacter species

BMC Microbiology, 2010
Background Catheter-associated urinary tract infection (CAUTI) is the most common nosocomial infection in the United States and is caused by a range of uropathogens.

From mouth to brain: Linking periodontal and peri‐implant dysbiosis to systemic inflammation and neuropathology

Periodontology 2000, EarlyView.
Abstract Background/Aim Growing evidence suggests that imbalances occurring within the human microbiota and deregulation of the host immune response may play a significant role in the development of neurodegenerative diseases. Materials and Methods A comprehensive narrative review of the latest experimental, clinical, and epidemiological insights was ...
