Fig 1. Cutaneous microbial diversity in 645 samples from 110 subjects, based on skin location and beta diversity analysis over time, by ethnic group.

Fig 1

The sequence depth is 3200/sample. Panel A. PCoA of clustering by sample location, based on unweighted pairwise UniFrac distances. The skin locations were Scalp [S (n = 215 samples)]; Arm [Ar (n = 215)]; Axilla [Ax (n = 215)]. Panel B. Analysis by ethnic group, including African-American [AA (n = 18 subjects/site)], East Asian [EA (n = 25)], Caucasian-American [CA (n = 16)], Latin American [LA (n = 16)], African-Continental [AC (n = 11)], and South Asian [SA (n = 19)]. PCoA of clustering of skin samples combining the three cutaneous sites, and the two time points; 1 = baseline and 2 = follow-up. Ellipses generally describe: axilla (black), scalp (yellow), and Arm (brown). Key to explain sites sampled and ethnic groups in all figures: The skin locations are colored as follows: yellow: Scalp (S); Brown: Arm (Ar); Black: Axilla (Ax). Ethnic groups are colored as: Orange: South Asian (SA); Light blue: Latin-American (LA); Purple: East Asian (EA); Red: African-American (AA); Blue: Caucasian-American (CA); Green: African-Continental (AC).
