P.3 2nd paragraph: "[Investigators] are now able to repeat the original calculation for the number of bacteria in the colon [ref 3]. Given 0.9×10^11 bacteria/g wet stool as derived in Box 2 and 0.4 L of colon, [they] find 3.8×10^13 bacteria in the colon with a standard error uncertainty of 25% and a variation of 52% SD over a population of 70 kg males. Considering that the contribution to the total number of bacteria from other organs is at most 10^12, [they] use 3.8×10^13 as [their] estimate for the number of bacteria across the whole body of the "reference man."" |
