Bacterial composition across donors and time points. a Typical scatter plot for two donors of the bacterial genera quantified by the sum of their top ten peptide intensities from fractionated proteome measurements. The eight most abundant genera are color coded. b Absolute quantification of the eight most abundant bacterial species depicted for each individual donor and (c) normalized to 100 %. d Mean genus quantities between males and females treated as groups from single run measurements. e Comparison of mean bacterial abundances at waking to the mean bacterial abundances in the postprandial state. f Reduction in bacterial abundance between the waking saliva samples and the postprandial samples
