The mammalian microbiota is comprised of 10-100 trillion microbial cells, outnumbering host cells by 10 to 1 and in humans adding over 8 million genes to our set of 22,000. Our understanding of the microbiota it still in its infancy, however its huge impact on host physiology is clear and the symbiotic relationship that exists between the host and microbiota has led to a new paradigm in our consideration of this system; is the microbiota actually a ‘virtual organ’ in its own right? | The mammalian microbiota is comprised of 10-100 trillion microbial cells, outnumbering host cells by 10 to 1 and in humans adding over 8 million genes to our set of 22,000.
