Biogeography of human-associated bacterial communities.
A) Summary of taxonomic distribution across 28 different body sites. B) Detailed view of gut microbiota for six individuals (M1, M2, M3 = male; F1, F2, F3 = female). The third digit of each sample indicates time point 1 or 2 for a given individual, while the four-letter identifier indicates the sampling type (Fcsp = swab directly from stool sample, Fcsw = swab of toilet paper). The four samples for each individual are colored identically on the human body map. The UPGMA tree at right indicates the relative similarity of different samples; edges whose children all originate from a single individual are assigned the appropriate color, while black branches cover samples from more than one individual.
