Microorganisms found on the Skin (Bacteria, Fungi and Yeast)
- Bacteria, Fungi and Yeast can live normally on the skin flora.
- Bacteria live peacefully on the superficial part of the skin (stratum corneum).
- They are around 7.5 million per square millimetre and are normally shed when the epidermis is renewed.
- Because of the tight overlapping junctions between dead corneocytes, organisms are unable to penetrate intact skin. If they do they are confronted to the first immune cells of the organisms = Langerhans Cells; Defective autoimmunity can lead to infections.
- Bacteria density and types vary according to different sites of the body.
