the estimate for the entire body was thus 100 trillion bacteria. In 1977, Professor Savage's team compared this number to that of human cells (10 trillion), arriving at the now-famous ratio.

Suzuki adds: "You can imagine that those microbes are on a gradient from 'free-living' to reliant on the human body environment. We have seen that some human gut bacteria are further along the ...
