Diversity and random forest models of oral microbiomes in periodontal health using publicly available data

Journal of Periodontology, EarlyView.
Abstract Background Evidence on the 16S metabarcoding of supragingival, subgingival, and salivary microbiomes in periodontal health remains limited. We aimed to analyze the diversity and potential of machine‐learning models of supragingival, subgingival, and salivary microbiomes in periodontal health. Methods A total of 848 samples (supragingival = 210;

A murine model of adult gastrointestinal colonization by Group B Streptococcus

Infection and Immunity
Group B Streptococcus (Streptococcus agalactiae, GBS) is a leading cause of invasive infections in neonates and adults. The adult gastrointestinal (GI) tract represents an understudied site of asymptomatic carriage with potential relevance for both ...

Ulcerative Colitis-associated E. coli pathobionts potentiate colitis in susceptible hosts

Gut Microbes, 2020
Ulcerative colitis (UC) is a chronic inflammatory condition linked to intestinal microbial dysbiosis, including the expansion of E. coli strains related to extra-intestinal pathogenic E. coli.

Dextran sodium sulfate confounds causal role of periodontitis in inflammatory bowel disease

Journal of Periodontology, EarlyView.
Abstract Background Emerging evidence supports a bidirectional link between periodontitis and inflammatory bowel disease (IBD). To investigate this relationship, experimental models commonly use dextran sodium sulfate (DSS) to induce colitis. However, DSS is presumed to selectively affect the colon, and its potential off‐target effects on the oral ...

In vitro dysbiotic oral biofilms deregulate the host immune response [PDF]

, 2017
EUROBIOFILMS 2017 - 5th European Congress on Microbial BiofilmsAn imbalance in the periodontal microbiota and dysbiosis deregulate the host immune response, leading to chronic inflammation.

Immunomicrobial pathogenesis of periodontitis: keystones, pathobionts, and host response [PDF]

Trends in Immunology, 2014
Recent studies have uncovered novel mechanisms underlying the breakdown of periodontal host-microbe homeostasis, which can precipitate dysbiosis and periodontitis in susceptible hosts. Dysbiotic microbial communities of keystone pathogens and pathobionts are thought to exhibit synergistic virulence whereby not only can they endure the host response but

Diet-induced expansion of pathobionts in experimental colitis [PDF]

Gut Microbes, 2013
Evidence presented in our recent study and elsewhere suggests that the interplay of dietary macronutrients with the intestinal lumen alters the microbial environment, and thus host-microbe interactions, in ways that are not always in a favorable, mutualistic fashion.

Electrolyzed saline as an alternative to chlorhexidine: Antimicrobial and biofilm volume outcomes in a 4‐day non‐brushing randomized controlled clinical trial

Journal of Periodontology, EarlyView.
Abstract Background The biofilm‐inhibitory effects of electrolyzed saline (EOS) vary widely due to differences in formulations and treatment methods. This study analyzed the impact of EOS on key oral microbial species and used serial 3D‐intraoral scans to evaluate its effects on de novo biofilm formation.

Eubiosis and dysbiosis: the two sides of the microbiota [PDF]

, 2016
The microbial ecosystem of the gastrointestinal tract is characterized by a great number of microbial species living in balance by adopting mutualistic strategies. The eubiosis/dysbiosis condition of the gut microbiota strongly influences our healthy and
