Effect of erythritol on microbial ecology of gingivitis biofilms.

Gingivitis is one of the most common oral infections in humans. While sugar alcohols such as erythritol are suggested to have caries-preventive properties, it may also have beneficial effects in prevention of gingivitis by preventing maturation of oral biofilms. The aim of this study was to assess the effect of erythritol on the microbial ecology and the gingivitis phenotype of oral microcosms.

The microbiome associated with equine periodontitis and oral health.

Equine periodontal disease is a common and painful condition and its severe form, periodontitis, can lead to tooth loss. Its aetiopathogenesis remains poorly understood despite recent increased awareness of this disorder amongst the veterinary profession. Bacteria have been found to be causative agents of the disease in other species, but current understanding of their role in equine periodontitis is extremely limited.

Profiling of Oral and Nasal Microbiome in Children With Cleft Palate.

Objective: To identify the oral and nasal microbial profile of cleft palate children and control children and to reveal interrelationships between the microbiome and the high prevalence of infectious diseases.

Design: Saliva and nasal samples of 10 cleft palate children and 10 age-matched control children were analyzed. Total microbial genomic DNA was isolated, polymerase chain reaction-denaturing gradient gel electrophoresis was applied to obtain fingerprints, and selected bands on fingerprints were sequenced.
