Single Molecular Force Sensing Reveals Fibronectin-Specific Binding Epitopes of Bacterial Curli Fimbriae [PDF]

Biophysical Journal, 2016
Curli are functional microbial amyloids that are major components of the complex extracellular matrix produced by Enterobacteriaceae. They play important functions in biofilm formation, bacterial invasion into host cells, and pathological processes which lead to numerous infections and autoimmune diseases.

Analisis Antibodi IgG Spesifik Fimbria Porphyromonas gingivalis dengan Metoda Elisa pada Penderita Early-Onset Periodontitis

Journal of Dentistry Indonesia, 2015
The adherence of bacteria to the host tissues is a first step in the development of infections. Bacterial fimbriae have been shown to play an important role in the interaction between bacteria and host cells or among bacterial cells.

Adhesion of Escherichia Coli to Nanostructured Surfaces and the Role of Type 1 Fimbriae

Nanomaterials, 2020
Bacterial fimbriae are an important virulence factor mediating adhesion to both biotic and abiotic surfaces and facilitating biofilm formation. The expression of type 1 fimbriae of Escherichia coli is a key virulence factor for urinary tract infections ...

Taurocholic Acid Is Associated With Disturbed Functional Connectivity in the Hippocampus of Patients With Depression

Advanced Science, EarlyView.
This study identifies elevated taurocholic acid (TCA) in Major Depressive Disorder patients. Gut microbiome‐associated TCA impairs hippocampal neurogenesis, triggers microglia activation, and elicits depression‐like behavior in mice via the S1PR2. In patients, functional neuroimaging reveals that serum TCA levels correlate with altered functional ...

The role of urease in the acid stress response and fimbriae expression in Klebsiella pneumoniae CG43

Journal of Microbiology, Immunology and Infection, 2022
Background/purpose: Two urease operons were identified in Klebsiella pneumoniae CG43, ure-1 and ure-2. This study investigates whether a differential regulation of the expression of ure-1 and ure-2 exists and how urease activity influences the acid ...

Evaluation of a Product Intended for Microbiological Control in Animal Production, and Its Combination With Halquinol

Animal Research and One Health, EarlyView.
Activo Liquid and Halquinol inhibit Salmonella and Escherichia coli in culture media. Activo Liquid exhibits bactericidal action, whereas HA is bacteriostatic, and their combination results in positive or indifferent interactions. This combination effectively inhibits E. coli throughout digestion simulation, thus reducing the required concentrations of

Unraveling the molecular basis of subunit specificity in P pilus assembly by mass spectrometry [PDF]

, 2008
P pili are multisubunit fibers essential for the attachment of uropathogenic Escherichia coli to the kidney. These fibers are formed by the noncovalent assembly of six different homologous subunit types in an array that is strictly defined in terms of ...

Bacterial Fimbriae and Their Peptides Activate Human Gingival Epithelial Cells through Toll-Like Receptor 2 [PDF]

Infection and Immunity, 2001
ABSTRACTGingival epithelial cells are a central component of the barrier between oral microflora and internal tissues. Host responses to periodontopathic bacteria and surface components containing fimbriae are thought to be important in the development and progression of periodontal diseases.
