A Synopsis of Gut Microbiota | Gut Foundation

Ten to 100 trillion microbial cells coexist with the human host in a symbiotic relationship. The human body may have anywhere from 10 to 1 microbial cells for every human cell, depending on the technique. The symbiotic interaction between the bacteria and their hosts can be advantageous as long as the host is healthy. There are hundreds of thousands of different kinds of bacteria in the gut microbiota (estimates vary).
