People from Different Continents Harbor Distinct Bacterial Strains

Caption

People from different continents harbor distinct bacterial strains. Gut microbiomes from five continents (red flags) contain strains with significantly different genes, as shown by their phylogenetic relationships (tree superimposed on the map with black lines indicating relatedness of the bacteria). Europe (green) and North America (blue) share two groups of strains, which are distinct from those in China (yellow), South America (purple) and Africa (red).
