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 ...

Phenotypic Expression of Type 1 Klebsiella pneumoniae Fimbriae in Escherichia coli HB101

مجلة مركز بحوث التقنيات الاحيائية, 2011
Four selected isolates of K. pneumoniae subsp. pneumoniae were tested for adhesion and the results revealed that isolates MK20, MK1, MK2, MK6 displayed adhesive capability with means (76.25 ± 6.0),(75.88 ± 5.13), (69.83 ± 8.43), (27.4±4.65) bacteria ...

Nanoparticles in Periodontology and Implant Dentistry: From Mechanisms to Clinical Applications

Journal of Periodontal Research, EarlyView.
Nanotechnology holds significant promise in improving dental care, yet there is a need for more reliable clinical studies to validate its effectiveness and safety. ABSTRACT Recent advances in nanotechnology are reshaping the landscape of periodontology and implant dentistry, particularly through the application of nanoparticles (NPs).

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

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 ...

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.

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

Subversion of a family of antimicrobial proteins by Salmonella enterica

Frontiers in Cellular and Infection Microbiology
Salmonella enterica is a food-borne pathogen able to cause a wide spectrum of diseases ranging from mild gastroenteritis to systemic infections. During almost all stages of the infection process Salmonella is likely to be exposed to a wide variety of ...

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.

The shaft of the type 1 fimbriae regulates an externalforce to match the FimH catch bond [PDF]

, 2013
Type 1 fimbriae mediate adhesion of uropathogenic Escherichia coli to host cells. It has been hypothesized that due to their ability to uncoil under exposure to force, fimbriae can reduce fluid shear stress on the adhesin-receptor interaction by which ...
