Binding of hemoglobin byPorphyromonas gingivalis [PDF]

FEMS Microbiology Letters, 1995
In this study, we investigated whether Porphyromonas gingivalis can bind hemoglobin as an initial step in the acquisition of heme from hemoglobin. The binding of human hemoglobin by P. gingivalis cells was determined using [3H]hemoglobin. Hemoglobin binding occurred rapidly, reversibly and specifically.

Modified Titanium Dental Implants: The Current Progress of Soft‐Tissue Integration Methods

Advanced NanoBiomed Research, EarlyView.
Dental implants are an established solution for tooth loss, yet achieving soft tissue integration (STI) around the transmucosal region remains a challenge. The natural tooth–gingiva interface is poorly replicated on titanium implants. This review explores surface modification strategies, ranging from surface chemistry and topography to biological ...

Novel fimbrilin PGN_1808 in Porphyromonas gingivalis

PLOS ONE, 2017
Porphyromonas gingivalis, a periodontopathic gram-negative anaerobic bacterium, generally expresses two types of fimbriae, FimA and Mfa1. However, a novel potential fimbrilin, PGN_1808, in P. gingivalis strain ATCC 33277 was recently identified by an in silico structural homology search.

Stress response of Porphyromonas gingivalis [PDF]

Oral Microbiology and Immunology, 1994
The heat shock response of Porphyromonas gingivalis was examined by 1 ‐ and 2‐dimensional polyacrylamide gel electrophoresis after metabolic labeling with [14C]‐amino acids. When P. gingivalis cells were shifted from 37° C to 42° C, elevated synthesis of 4 proteins with the apparent molecular weight of 92, 80, 74, and 62 kDa was observed, and synthesis

脂肪滴はヒト肝細胞株におけるPorphyromonas gingivalisのオートファジー・リソソームシステムを介した排除機構に影響する [PDF]

, 2017
Recent studies have shown that infection with Porphyromonas gingivalis, a major periodontal pathogen, hastens the progression of non-alcoholic fatty liver disease (NAFLD). However, the intracellular fate of P.

Interactions of Porphyromonas gingivalis with oxyhaemoglobin and deoxyhaemoglobin [PDF]

Biochemical Journal, 2002
When grown on blood-containing solid media, the anaerobic periodontal pathogen Porphyromonas gingivalis produces a haem pigment, the major component of which is the μ-oxo bishaem of iron protoporphyrin IX [Smalley, Silver, Marsh and Birss (1998) Biochem. J. 331, 681–685]. In this study, μ-oxo bishaem generation by P.

Beyond antimicrobials: Ecological nano‐strategies for rebalancing dysbiotic oral microbial homeostasis

BMEMat, EarlyView.
Oral microbial homeostasis, a dynamic host‐microbe balance, is vital in infectious diseases. Conventional antibiotics often disrupt this homeostasis, spurring interest in nanomaterials for oral microbial homeostasis rebalancing. This review outlines nanomaterial strategies across three ecological levels (population/community, ecosystem, and cross ...

Genetic exchange and reassignment in Porphyromonas gingivalis [PDF]

Journal of Oral Microbiology, 2018
Porphyromonas gingivalis is considered a keystone pathogen in adult periodontitis but has also been associated with systemic diseases. It has a myriad of virulence factors that differ between strains. Genetic exchange and intracellular genome rearrangements may be responsible for the variability in the virulence of P. gingivalis.

Bacteremia in horses undergoing routine dental prophylaxis: Before, during, and after the procedure

Equine Veterinary Journal, EarlyView.
Abstract Background Transient bacteremia after dental procedures is well‐documented in the literature, but the prevalence and clinical significance in horses remains largely unexplored. Objectives To assess whether routine dental prophylaxis in clinically healthy horses is associated with detection of bacteria in blood, using culture and 16S rDNA ...

Mining Oral Probiotics Based on Their Pathogen Inhibition and Deodorization Roles

Food Bioengineering, EarlyView.
A promising oral probiotic strain Streptococcus salivarius MY‐6 stood out from 41 candidate lactic acid bacteria through the high‐throughput strategy based on its inhibitions of the growth and biofilm formation of the main oral pathogens Fusobacterium nucleatum and Porphyromonas gingivalis, as well as its elimination of oral malodor‐associated ...
