Epidermal microbiota is much more abundant and variable (strongly affected by environmental contacts) than dermal microbiota. A subset of most frequent members of the epidermic microbiota constitute a very stable and universal (preserved in different individuals) dermal bacterial community, adapted to the nutrients of the dermal compartment. In the boxes below, listed by frequency, the epidermal genera with high representation in the dermal compartment are highlighted in bold characters.
