a

The taxonomic rank is provided in parentheses only if the species information is not defined in the reference. Oral bacteria are defined per the following criteria: 1) bacteria identified as a constituent of the oral microbiome by the Human Oral Microbiome Database (Escapa et al. 2018) and 2) bacteria having higher abundance in the oral tissues than in the gut samples. The percentage abundance in the saliva, gingiva, buccal mucosa, and stool in healthy individuals, based on the NIH Human Microbiome Project (HMP1), is shown. In addition, some bacteria that were previously reported as bacteria involved in oral pathology are listed as possible oral bacteria even if they do not meet criterion 2. References are provided in Appendix Table 1.

Amplicon sequence variants also match some other taxa (likely in the same genus).
