Uropathogenic Escherichia coli P and Type 1 fimbriae act in synergy in a living host to facilitate renal colonization leading to nephron obstruction. [PDF]

PLoS Pathogens, 2011
The progression of a natural bacterial infection is a dynamic process influenced by the physiological characteristics of the target organ. Recent developments in live animal imaging allow for the study of the dynamic microbe-host interplay in real-time ...

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 ...

The export systems of type 1 and F1C fimbriae are interchangeable but work in parental pairs [PDF]

Journal of Bacteriology, 1995
Type 1 and F1C fimbriae are surface organelles of Escherichia coli which mediate receptor-specific binding to different host surfaces. Such fimbriae are found, among others, on strains associated with urinary tract infections. Biosynthesis of type 1 and F1C fimbrial organelles requires individual, specialized two-component assembly systems.

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).

Chaperone-usher fimbriae of Escherichia coli [PDF]

, 2013
Chaperone-usher (CU) fimbriae are adhesive surface organelles common to many Gram-negative bacteria. Escherichia coli genomes contain a large variety of characterised and putative CU fimbrial operons, however, the classification and annotation of ...

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

Antigenic relationships among type-1 fimbriae of Enterobacteriaceae revealed by immuno-electronmicroscopy [PDF]

Journal of Medical Microbiology, 1987
Antigenic relationships among type-1 fimbriae of 40 strains of Enterobacteriaceae representing 19 species and seven genera were determined by immuno-electronmicroscopy. Ten distinct antigenic groups were distinguished. Intra- and inter-generic relationships were observed although some antigenic groups were species-specific only. Antigenic relationships

Edwardsiella piscicida type III protein EseJ suppresses apoptosis through down regulating type 1 fimbriae, which stimulate the cleavage of caspase-8

, 2020
The type III secretion system effector EseJ plays a regulatory role inside bacteria. It suppresses the adherence of Edwardsiella piscicida (E. piscicida) to host epithelial cells by down regulating type 1 fimbriae.

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 ...

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 ...
