What it means
The old claim was ten bacterial cells to every human one, and a careful recount in 2016 put the ratio far nearer to one to one, with the exact figure shifting after every visit to the bathroom. Either way the number is startling, and the bacteria are not passengers: they digest fiber, make vitamins and train the immune system.
