The number of micro-organisms in the gut exceeds the total
number of all cells in the human body.
The total mass of gut microbiota ranges from 1 to 3 kg.
An adult weighing 70 kg and height 170 cm contains
around 30 trillion cells and 49 trillion gut bacteria.
Microbiota is an ecosystem dominated by bacteria, mainly strict
anaerobes that do not need oxygen to live. It also contains other
micro-organisms: viruses and bacteriophages, protozoa, archaea
(unicellular living organisms) and fungi. In total there are over
7,000 strains in the microbiota. The gut makes up 2/3 of the
immune system.
According to scientists, each gut cell of an adult provides nutrients to 100,000
other cells in the body.
