Alpha diversity measures at 1000 sequences per sample in the different sites of healthy skin.

Significant differences between skin sites were mainly observed when comparing mucosal surfaces with haired skin sites, e.g. conjunctiva versus axilla. The Chao 1 index estimates species richness at higher sequencing depth; the observed species represents the number of observed species in 1,000 sequences; the Shannon is a diversity index that takes into account abundance and evenness of species.Superscripts represent sites that were significantly different when compared to the skin sites in the first column. A: Axilla; N: Nostril; CP: Concave pinna; DN: Dorsal nose; G: Groin.
