  1. Column 1 shows the mean percent value for the 16S rRNA gene profile of 5 major phyla, and of all minor bacterial phyla combined. This is compared with similar profiles from the jejunal mucosal data of Dlugoz et al. [15], and averaged data from two studies for oral saliva (Guerrero -Preston et al. [26] and Oh et al. [22]). Colon data is from normal adults (Turnbaugh et al. [24]) and aged individuals Claesson [25]
