Question

You can find 20 million microscopic animals living on a square inch of human skin. Skin sounds like Tokyo.

Answer 1

To a micro-organism, the human skin seems very much like the planet Earth seems to us. Just like our planet, our bodies contain numerous different environments, ranging from dry deserts (e.g. the forearm) to tropical forests (e.g. the groin). Each environment possesses certain advantages and disadvantages and different micro-organisms have adapted to certain regions of the body for their particular needs.

The surface of the skin itself comprises several distinct environments. Areas such as the axilla (armpit), the perineum (groin) and the toe webs provide typically moister regions for bacterial growth. These "tropical forest" environments often harbour the largest diversity amongst the skin flora. Typical organisms include Staphylococcus aureus, Corynebacterium and some Gram-negative bacteria. The bulk of the human skin surface, however, is much drier and is predominantly inhabited by Staphylococcus epidermidis and Propionobacterium
