The person-to-person transmission landscape of the gut and oral microbiomes. Transmission

The human microbiome is an integral component of our body and a co-determinant of several health conditions. However, how the human microbiome is shaped via person-to-person microbial transmission and the extent to which interpersonal relations impact the individual genetic makeup of the microbiome and its spread within and across populations remain largely unknown. We assessed this in >9700 gut and oral metagenomes.
