Characteristics of the salivary microbiota in cheilitis granulomatosa.

CONCLUSIONS: The composition and structure of bacterial communities in CG patients were different from HC. Most of the genera observed in CG patients were associated with periodontitis and pulp infection. These findings might be helpful in understanding the etiology of CG. Further study will be needed to confirm these findings and explore the underlying pathological mechanism. PMID: 31655830 [PubMed - as supplied by publisher]

In this study, we analyzed and compared the intestinal microbiota composition of patients with idiopathic focal epilepsy (n = 30) and healthy volunteer group (n = 10) by 16s ribosomal DNA sequencing. Proteobacteria phylum was found to be higher in patients with epilepsy (25.4%) than in healthy volunteers group (1.5%). The genera of Campylobacter, Delftia, Haemophilus, Lautropia, Neisseria among Proteobacteria phylum were found to be statistically significantly higher in patients with epilepsy than in healthy volunteers (p

CONCLUSION:A number of studies have showed an association between PD and IBD. Both diseases share genetic and environmental etiological factors. The precise role of intestinal bacteria remains vague. The periodontal microbiota that might be involved in the association of these diseases are Fusobacterium nucleatum, Campylobacter rectus and Campylobacter concisus. Fungal and viral microbiota dysbiosis should also be evaluated as common pathogenic pathways in IBD and periodontal disease.

Authors: Karatas O, Balci Yuce H, Aydemir Turkal H Abstract BACKGROUND: The aim of this study was to evaluate dental plaque compositions, vascular endothelial growth factor (VEGF) and hypoxia-inducible factor (HIF) 1-alpha levels in gingival crevicular fluid (GCF) at hypofunctional and normofunctional teeth in healthy individuals and chronic periodontitis patients. METHODS: Sixty systemically healthy individuals were enrolled. Study groups were: group 1 hypofunctional healthy group (group 1, N.=15); group 2 hypofunctional periodontitis group (group 2, N.=15); group 3 normofunctional healthy group (group 3, N.=1...

Fusobacteria are common obligately anaerobic Gram-negative bacteria of the oral cavity that may act as a bridge between early and late colonizing bacteria in dental plaque, and have a role in oral and extra-oral infections. Fusobacterium nucleatum has a crucial role in oral biofilm structure and ecology, as revealed in experimental and clinical biofilm models. The aim of this study was to investigate the impact of various Fusobacterium species on in vitro biofilm formation and structure in three different oral biofilm models namely a supragingival, a supragingival “feeding”, and a subgingival biofilm model. The...

This study evaluated the composition of periodontal microbiota with the checkerboard hybridization technique and its correlation with TNF-α, MM P-8, and MMP-9 evaluated with ELISA, of 80 patients (45 healthy, and 35 with chronic periodontitis). The frequency of the 18 species evaluated was higher in patients with bone loss compared with control group. TNF-α in gingival crevicular fluid was significantly higher in bone loss group (p

This study evaluated the effects of a clay-mineral based product (CM) on PaM, EpM, fermentation parameters, and epithelial gene expression in cows fed a high-concentrate diet. Eight rumen-cannulated non-lactating Holstein cows received a concentrate mix supplemented with CM or not (CON) in a change-over design with an initial 100% roughage diet phase (RD, 1 week), followed by intermittent 65%-high-concentrate-diet phases (HC1, HC2; 1 and 2 week duration, respectively), interrupted by 1 week roughage only. Rumen samples for short-chain fatty acids, ammonia, and lactate quantification, as well as PaM, and epithelial biopsies...
