What lives on our skin: ecology, genomics and therapeutic opportunities of the skin microbiome

Open access
Scharschmidt, Tiffany C., Fischbach, Michael A.·2013·Drug Discovery Today: Disease Mechanisms

Abstract

Our skin is home to a rich community of microorganisms. Recent advances in sequencing technology have allowed more accurate enumeration of these human-associated microbiota and investigation of their genomic content. Staphylococcus, Corynebacterium and Propionibacterium represent the dominant bacterial genera on skin and illustrate how bacteria adapt to life in this harsh environment and also provide us with unique benefits. In healthy states, our skin peacefully co-exists with commensal bacteria while fending off potentially dangerous invaders. Disruption of this equilibrium, termed "dysbiosis", can result from changes in the composition of our skin bacteria, an altered immune response to them, or both and may be a driving factor in certain types of inflammatory skin disease. Engineering topical therapeutics to favourably influence the composition of our skin flora and optimize interactions with them represents a real therapeutic opportunity for the field of dermatology and warrants additional investigation into skin microbial ecology and disease mechanisms related to host-microbe dysbiosis.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Sebaceous glands produce triglycerides, free fatty acids, and waxes that provide additional nutrients for microbial metabolism and growth.

    “Sebaceous glands produce triglycerides, free fatty acids, and waxes that also provide additional nutrients for metabolism and growth (28).”

    From <i>Candida auris</i> metabolism and growth preferences in physiologically relevant skin-like conditions (2026) · cites this paper as [28]

    The Key Players sections on Corynebacterium and Propionibacterium say that microbes obtain nutrients from lipid-rich sebum, supporting the general nutrient claim. Our copy does not specify that sebaceous glands produce triglycerides, free fatty acids, and waxes, or establish that each of those components provides microbial nutrients. No page numbers are available in our copy. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • Sweat glands secrete glucose, amino acids, salts, and other nutrients that microorganisms can use to metabolize and grow.

    “Sweat glands (eccrine and apocrine) secrete glucose, amino acids, salts, and other nutrients that microorganisms can use to metabolize and grow (28).”

    From <i>Candida auris</i> metabolism and growth preferences in physiologically relevant skin-like conditions (2026) · cites this paper as [28]

    The Key Players > Staphylococcus says sweat contains salt and urea that bacteria may use as a nitrogen source; The Key Players > Corynebacterium says some bacteria rely on vitamins in sweat for survival. The paper does not state that eccrine and apocrine glands secrete glucose or amino acids for microbial growth. Page numbers are unavailable in our copy. (LLM, conf=0.86)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
