Porphyromonas gingivalis fimbriae

Journal of Oral Microbiology, 2013
Marginal periodontitis is not a homogeneous disease but is rather influenced by an intricate set of host susceptibility differences as well as diversities in virulence among the harbored organisms. It is likely that clonal heterogeneity of subpopulations

Antimicrobial Activity of Ultraviolet C Light as a Potential Novel Treatment for Moraxella bovis Infection—An In Vitro Study

Veterinary Ophthalmology, EarlyView.
ABSTRACT Objective To investigate the antimicrobial effect of 275 nm wavelength ultraviolet C (UV‐C) light on M. bovis using an affordable, broadly available modified handheld device and to determine if photoreactivation plays a role in bacterial resistance to UV‐C. Methods UV‐C therapy (UVCT) was evaluated in vitro using triplicates of 3 M.

Surface Display of Type 1 Fimbriae on Shigella flexneri Induces Antigen-Specific Immune Response via Oral Route

Vaccines
Background: Live attenuated bacteria are promising candidates for mucosal vaccine delivery due to their ability to elicit robust immune responses. FimH is the adhesion protein of type 1 fimbriae, which is used as mucosal adjuvants.

yqhG Contributes to Oxidative Stress Resistance and Virulence of Uropathogenic Escherichia coli and Identification of Other Genes Altering Expression of Type 1 Fimbriae

Frontiers in Cellular and Infection Microbiology, 2019
Urinary tract infections (UTIs) are common bacterial infections and the vast majority of UTIs are caused by extraintestinal pathogenic Escherichia coli (ExPEC) strains referred to as uropathogenic E. coli (UPEC).

Engineered Probiotics: The Next‐Generation Therapeutics to Combat Antibiotic‐Resistant Bacterial Infections

Food Frontiers, Volume 7, Issue 2, March 2026.
Engineered probiotics secretes fusion proteins which potentially neutralized the toxins secreted by other microbial communities. ABSTRACT On a global scale, the escalating burden of infectious diseases, predominantly attributed to bacterial pathogens, especially drug‐resistant strains, has progressed into a critical concern for clinical management and ...

Difference in the regulation of IL-8 expression induced by uropathogenic E. coli between two kinds of urinary tract epithelial cells

Journal of Biomedical Science, 2009
Bacterial adherence to epithelial cells is a key virulence trait of pathogenic bacteria. The type 1 fimbriae and the P-fimbriae of uropathogenic Escherichia coli (UPEC) have both been described to be important for the establishment of urinary tract ...

Intestinal Colonization Traits of Pandemic Multidrug-Resistant Escherichia coli ST131 [PDF]

, 2018
Background. Epidemiological studies point to the gut as a key reservoir of multidrug resistant Escherichia coli multilocus sequence type 131 (ST131), a globally dominant pathogenic clone causing urinary tract and bloodstream infections.

The dysregulation of innate immunity by Porphyromonas gingivalis in the etiology of Alzheimer's disease

Journal of Internal Medicine, Volume 299, Issue 3, Page 328-348, March 2026.
Abstract The etiology of Alzheimer's disease (AD) remains under active debate. In this perspective, we explore the hypothesis that a primarily infection‐caused chronic dysregulation and weakening of human innate immunity via the underexpression, degradation, and inactivation of innate immune proteins necessary for direct antimicrobial effects and ...

Antibiotic Resistance, Biofilm Genes, and smeDEF Efflux Pump in Clinical Stenotrophomonas maltophilia Isolates From Iran

MicrobiologyOpen, Volume 15, Issue 1, February 2026.
Iranian clinical Stenotrophomonas maltophilia isolates showed high susceptibility to trimethoprim/sulfamethoxazole, minocycline, and levofloxacin, but marked resistance to ceftazidime and ticarcillin‐clavulanate, alongside widespread biofilm production and resistance genes.

Role of type 1 and type 3 fimbriae in Klebsiella pneumoniae biofilm formation [PDF]

, 2010
Background Klebsiella pneumoniae is an important gram-negative opportunistic pathogen causing primarily urinary tract infections, respiratory infections, and bacteraemia. The ability of bacteria to form biofilms on medical devices, e.g.
