Comparison of the gut microbiota of obese individuals from different geographic origins. Microbiota of individuals with different origins

Few studies have examined the interaction of human geography, microbial community structure and obesity. We tested obese adult volunteers from France, Saudi Arabia, French Polynesia and from a traditional population in the village of Trois-Sauts in French Guiana by sequencing the V3-V4 region. We also sequenced two homemade fermented cachiri beers that are highly consumed by Amazonians. The gut microbiomes of the French and Saudis had significantly less richness and biodiversity than those of the Amazonians and Polynesians , whereas the Amazonians presented significantly stricter anaerobic genera than the Saudis, French and Polynesians .
