How big the Human Microbiome is?

The human gut harbors 100 trillion different microbial organisms. More than 1000 species of bacteria reside in the gastrointestinal tract and the collective genome of intestinal microbes is estimated to contain approximately 100 times more genes than the human genome


The Microbiome comprises of collective genomes of microbiota inhabiting us, namely protozoa, archaea, eukaryotes, viruses and predominantly 
bacteria that live symbiotically on and within various sites of the human body.

Role of Gut Microbiota

The normal gut microbiota imparts specific function in host nutrient metabolism, xenobiotic and drug metabolism, maintenance of structural integrity of the gut mucosal barrier, immunomodulation, and protection against pathogens.

How it affects:

Affected by a variety of factors including gestation stage, birthing and infant feeding method, exposure to stress, environment, diet, medications, stage of lifecycle, and diseases
