Association of <i>Fusobacterium nucleatum</i> in human saliva with periodontal status and composition of the salivary microbiome including periodontopathogens

We characterized the composition of the saliva microbiome in groups based on the abundance of <i>Fusobacterium nucleatum</i>. There is a lot of periodontitis in subjects with a high abundance of <i>F. nucleatum</i>. The diversity of the saliva microbiome was different among groups based on the abundance of <i>F. nucleatum</i>. The abundance of <i>F. nucleatum</i> correlated with various periodontopathogens including red complex. These results support the influence of the abundance of <i>F. nucleatum</i> in saliva on periodontal status and the composition of the salivary microbiome, including the red complex and periodontopathogens.
