Constraints on lateral gene transfer in promoting fimbrial usher protein diversity and function [PDF]
Open Biology, 2017 Fimbriae are long, adhesive structures widespread throughout members of the family Enterobacteriaceae. They are multimeric extrusions, which are moved out of the bacterial cell through an integral outer membrane protein called usher.

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

Direct evidence that the FimH protein is the mannose-specific adhesin of Escherichia coli type 1 fimbriae [PDF]
Infection and Immunity, 1990 Type 1 fimbriae of Escherichia coli are surface organelles which mediate binding to D-mannose-containing structures. By direct binding of FimH to D-mannose attached to a carrier protein, we demonstrated that this protein was uniquely responsible for the receptor specificity.

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.

Epithelial cell binding of group A streptococci by lipoteichoic acid on fimbriae denuded of M protein. [PDF]
The Journal of experimental medicine, 1976 Group A streptococci were treated with various enzymatic and chemical agents in an attempt to dissociate the type-specific M protein from intact surface "fimbriae." Mild peptic digestion at pH 5.8, which was previously shown to extract serologically active M antigen from intact streptococci had little visible effect on the fimbriae even though ...

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

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.

CORYNEBACTERIUM: FEATURES OF THE STRUCTURE OF THE BACTERIAL CELL
Журнал микробиологии, эпидемиологии и иммунобиологии, 2017 In a review of the features of the bacterial cells are Corynebacterium structure: characterized by an upper layer, highly organized cell wall, cytoplasmic membrane, cytoplasm, nucleoid. Described in detail the structure of the upper layer containing pili
