Extended Data Fig. 9: Highly-transmitted SGBs in oral samples.
From: The person-to-person transmission landscape of the gut and oral microbiomes

Same-family (green) to different-family (purple) genetic distance comparisons for the three SGBs consistently and significantly highly-transmitted in oral metagenomes. Strain identity thresholds were set as the 3rd percentile of the unrelated individual comparisons (dashed line).
