Gut flora (gut microbiota, or gastrointestinal microbiota) is the complex community of microorganisms that live in the digestive tracts of humans and other animals, including insects. The gut metagenome is the aggregate of all the genomes of gut microbiota. The gut is one niche that human microbiota inhabit.
The composition of gut microbiota is unique to each individual, just like our fingerprints. Our gut microbiota contains tens of trillions of bacteria â ten times more cells than in our body. There are more than 3 millions microbial genes in our gut microbiota â150 times more genes than in the human genome.
