P.74 2nd paragraph:"The density of the bacterial flora in the GI tract is huge: it varies from 10^3/mL near the gastric outlet, to 10^10/mL at the ileo-cecal valve, to 10^11 to 10^12/mL in the colon. The total microbial population (ca. 10^14) [primary source] exceeds the total number of cells in the GI tract. About 500 to 1,000 different species exist, a biomass that weights about 1.5 kg [primary source]." |
