^aThe relative abundance (%) of bacterial species observed in this study. Bacterial samples from the tongue, palate, and incisors were pooled.
^bThe relative abundance (%) of bacterial species obtained from an analysis of data generated by Keijer et al. [6]. Saliva from 71 individuals and supragingival plaque from 98 individuals was pooled.
^cNot present in the study by Keijer et al. but found in the study by Paster et al. [24]
^dTotal contribution of bacterial species shared between mouse and humans
