P.9 2nd paragraph: "The Ratio of Bacteria to Human Cells in the Adult Body: With the revised estimates for the number of human (3.0×10^13) and bacterial cells (3.8×10^13) in the body (the numerator and denominator of the B/H ratio), [investigators] can give an updated estimate of B/H = 1.3, with an uncertainty of 25% and a variation of 53% over the population of standard 70 kg males. This B/H value of about 1:1 (with the associated uncertainty range) should replace the 10:1 or 100:1 values that are stated in the literature until more accurate measurements become available. [They] note that if one chooses to compare the number of bacteria in the human body (3.8×10^13) to the number of nucleated human cells (≈0.3×10^13), the ratio will be about 10:1." |
