Abstract

Gene swapping in the human microbiome Horizontal gene transfer — the exchange of genetic material between different species or lineages — is an important factor in bacterial evolution. A study of human microbiome data comprising more than 2,000 full bacterial genomes shows that this environment is a hotbed of horizontal gene transfer: pairs of bacteria isolated from the human body are 25-fold more likely to share transferred DNA than pairs from other environments. Thus microbial ecology — rather than phylogeny or geography — is the most important driver of the patterns of horizontal gene exchange. Further analysis revealed 42 unique antibiotic-resistance genes that had been transferred between human and agricultural isolates, and 43 transfers across national borders.
