Ever wondered about the origin of the bacteria that call our faces home? 🤔 Our new preprint dives into the fascinating dynamics of the human facial skin microbiome (FSM) and explores the natural history of important microbiome species on people at high resolution. 🧫🧵
Highly-resolved within-species dynamics in the human facial skin microbiome https://www.biorxiv.org/content/10.1101/2024.01.10.575018v1
Human facial skin microbiomes (FSMs) on adults are dominated by just two bacterial species, Cutibact
🧫🌳 Using 4,055 isolate genomes from 8 families, we identified extremely closely related lineages of C. acnes & S. epidermidis. Since lineages arose from recent ancestors on people (<100 SNPs/genome in the entire lineage) we could use them to directly trace transmissions with high precision.
