It is now established that microbes make up more than 95% of the living mass on the planet and colonize all its ecosystems. Notably, bacteria have colonized the digestive tract of animals, forming communities of various complexities, that is maximal in the distal part of the mammals’ gut. Because of this important microbial community, the human colon is described as the most ecologically dense site of bacteria on earth, with a total of bacteria estimated at around 10,13, comparable with the total number of cells in the human body.
