Research Abstract

A metagenomic analysis of dental plaque microbiota obtained from periodontal healthy subjects and periodontitis patients was performed. The deep sequencing of the seven DNA samples detected total of 996 species and revealed substantially greater microbial diversity in the dental plaque than previously known. The functional binning profiles of these samples were compared with other environmental metagenome datasets such as human gut microbiota. Enrichments of genes in the categories of 'Defense mechanism' and 'carbon hydrate transport and metabolism' were observed in plaque samples.
