In Silico Destruction of Porphyromonas gingivalis Fimbriae by Streptomyces sp. Strain GMY02 [PDF]

BIO Web of Conferences, 2023
Porphyromonas gingivalis, a keystone pathogen in chronic periodontitis, has fimbria as one of the most important virulence factors because it plays a vital role in the pathogenesis of P. gingivalis infection.

P-fimbriae of Escherichia coli: immuno- and protein-chemical characterization of fimbriae from two pyelonephritogenic strains [PDF]

FEMS Microbiology Letters, 1983
Many types of fimbriae have been described on pathogenic Escherichia coli strains. K88, K99, C F A / I and C F A / I I are fimbrial antigens on enterotoxigenic E. coli strains. The K88 antigens are found on strains causing diarrhoea in piglets [1], whereas strains with the K99 antigen cause diarrhoea in calves and lambs [2].

Structural and antigenic characterization of a novel genotype of Mfa1 fimbriae in Porphyromonas gingivalis

Journal of Oral Microbiology, 2023
Background Mfa1 fimbriae of the periodontal pathogen Porphyromonas gingivalis are responsible for biofilm formation and comprise five proteins: Mfa1–5. Two major genotypes, mfa170 and mfa153, encode major fimbrillin.

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

Fimbria-associated proteins of Bacteroides loescheii PK1295 mediate intergeneric coaggregations [PDF]

Journal of Bacteriology, 1987
Bacteroides loescheii PK1295 serves as a coaggregation bridge between Streptococcus sanguis 34 and Actinomyces israelii PK14, two gram-positive oral bacteria that are otherwise unable to coaggregate. Whereas coaggregation with S. sanguis 34 is inhibited by lactose, no simple sugar was found that inhibited coaggregation with A.

Aggregative adherence fimbriae form compact structures as seen by SAXS

Scientific Reports, 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

Protein interaction studies of curli fimbriae in Escherichia coli biofilms [PDF]

Bioinformation, 2019
Catheter-associated urinary tract infections (CAUTIs) caused by biofilms on indwelling medical devices are the most common type of nosocomial infections, a major health concern due to complications and frequent recurrence. The infections are most often caused by Escherichia coli.

Production of a subunit vaccine candidate against porcine post-weaning diarrhea in high-biomass transplastomic tobacco [PDF]

, 2012
Post-weaning diarrhea (PWD) in piglets is a major problem in piggeries worldwide and results in severe economic losses. Infection with Enterotoxigenic Escherichia coli (ETEC) is the key culprit for the PWD disease.

Porphyromonas gingivalis fimbriae induce a 68-kilodalton phosphorylated protein in macrophages [PDF]

Infection and Immunity, 1994
The present study was performed to examine whether Porphyromonas gingivalis fimbriae induce specifically a protein kinase-mediated phosphorylated protein that is involved in the mechanism of signal transduction. The fimbriae induced a 68-kDa phosphorylated protein (pp68) in a dose-dependent manner in mouse peritoneal macrophages. A marked appearance of

Mfa4, an Accessory Protein of Mfa1 Fimbriae, Modulates Fimbrial Biogenesis, Cell Auto-Aggregation, and Biofilm Formation in Porphyromonas gingivalis. [PDF]

PLoS ONE, 2015
Porphyromonas gingivalis, a gram-negative obligate anaerobic bacterium, is considered to be a key pathogen in periodontal disease. The bacterium expresses Mfa1 fimbriae, which are composed of polymers of Mfa1.
