Probiotics alter biofilm formation and the transcription of Porphyromonas gingivalis virulence-associated genes

Journal of Oral Microbiology, 2020
Background and Objective The potential of probiotics on the prevention and control of periodontitis and other chronic inflammatory conditions has been suggested. Lactobacillus and Bifidobacterium species influence P.

Glycosylation Analysis and Protein Structure Determination of Murine Fetal Antigen 1 (mFA1) [PDF]

European Journal of Biochemistry, 1997
By means of sequence analysis, murine fetal antigen 1 (mFAl) isolated from Mus musculus amniotic fluid was shown to be the circulating protein of the δ‐like protein, stromal‐cell‐derived protein 1 (SCP‐1) and preadipocyte factor 1 (Pref‐1) gene products. The protein contains 36 cysteine residues arranged in six epidermal‐growth‐factor‐like domains. The

Structural and functional studies of Porphyromonas gingivalis fimbrial proteins

Journal of Oral Microbiology, 2017
Porphyromonas gingivalis expresses two forms of fimbriae, FimA and Mfa1. Each fimbria consists of five proteins; FimA-E and Mfa1-5. While the assembly of the type-1 fimbriae from Escherichia coli is well studied; the chaperone-usher pathway, very little ...

Cryptococcus gattii in AIDS Patients, Southern California

Emerging Infectious Diseases, 2005
Cryptococcus isolates from AIDS patients in southern California were characterized by molecular analyses. Pheromone MFα1 and MFa1 gene fragments were polymerase chain reaction–amplified with fluorescently labeled primers and analyzed by capillary ...

Identification of Mfa5-2 as a structural component of Mfa1 fimbriae in Porphyromonas gingivalis

Journal of Oral Biosciences
The periodontal pathogen Porphyromonas gingivalis produces Mfa1 fimbriae, which play an important role in biofilm formation and bacterial colonization. In P. gingivalis ATCC 33277, Mfa1 fimbriae are composed of the major Mfa1 subunit and the accessory proteins Mfa3, Mfa4, and Mfa5. Some P. gingivalis strains harbor an additional Mfa5-related gene (mfa5-

The Keystone‐Pathogen Hypothesis Updated: The Role of Porphyromonas gingivalis in Periodontitis

Journal of Periodontal Research, EarlyView.
Porphyromonas gingivalis orchestrates a coordinated manipulation of immune and inflammatory responses in periodontal tissues which leads to the generation of a dysbiotic, subgingival biofilm community, and progression of periodontitis. The type 9 secretion system, lipid A modification, and the formation of outer membrane vesicles are important ...

Periodontal Medicine Rewired: Mechanisms Linking Periodontitis to Systemic Diseases

Journal of Periodontal Research, EarlyView.
This review reorganizes decades of research in periodontal medicine into a multi‐dimensional framework, illustrating how periodontitis influences systemic health through at least seven interconnected mechanisms. ABSTRACT Periodontitis is now recognized not merely as a localized oral condition but as a systemic disease linked to over 70 communicable and

Novel and emerging antimicrobial strategies in the management of oral infections

Periodontology 2000, EarlyView.
Abstract Background Antibiotics marked a pivotal turning point in human civilization, enhancing social interactions and extending human life expectancy. In addition to their success in treating systemic infectious diseases, they have significantly improved periodontal treatment outcomes as an adjunct therapy.

Fluoroacetate in plants - a review of its distribution, toxicity to livestock and microbial detoxification

Journal of Animal Science and Biotechnology, 2017
Fluoroacetate producing plants grow worldwide and it is believed they produce this toxic compound as a defence mechanism against grazing by herbivores. Ingestion by livestock often results in fatal poisonings, which causes significant economic problems ...

Heterogeneous Systemic IgG Responses to Porphyromonas gingivalis Gingipains in Advanced Periodontitis

Clinical and Experimental Dental Research, Volume 12, Issue 3, June 2026.
ABSTRACT Objectives To evaluate serum IgG responses against Porphyromonas gingivalis gingipains RgpB and Kgp in patients with stage III and IV periodontitis and examine associations with clinical periodontal parameters. Materials and Methods This exploratory cross‐sectional study included participants with advanced periodontitis (Stage III and IV ...
