The human skin microbiome.

Nat Rev Microbiol 2018 03 15;16(3):143-155. Epub 2018 Jan 15.

Microbial Genomics Section, National Human Genome Research Institute, National Institutes of Health, Bethesda, Maryland 20892, USA.

Functioning as the exterior interface of the human body with the environment, skin acts as a physical barrier to prevent the invasion of foreign pathogens while providing a home to the commensal microbiota. The harsh physical landscape of skin, particularly the desiccated, nutrient-poor, acidic environment, also contributes to the adversity that pathogens face when colonizing human skin. Despite this, the skin is colonized by a diverse microbiota. Read More

Understanding the role of Propionibacterium acnes in acne vulgaris: The critical importance of skin sampling methodologies.

Clin Dermatol 2017 Mar - Apr;35(2):118-129. Epub 2016 Oct 27.

Department of Medical Biosciences/Pathology, Umeå University, Umeå, Sweden. Electronic address:

Acne vulgaris is a chronic inflammatory skin condition classified by the Global Burden of Disease Study as the eighth most prevalent disease worldwide. The pathophysiology of the condition has been extensively studied, with an increase in sebum production, abnormal keratinization of the pilosebaceous follicle, and an inflammatory immune response all implicated in its etiology. One of the most disputed points, however, is the role of the gram-positive anaerobic bacterium Propionibacterium acnes in the development of acne, particularly when this organism is also found in normal sebaceous follicles of healthy skin.

Discovery of a Novel Seminal Fluid Microbiome and Influence of Estrogen Receptor Alpha Genetic Status.

Sci Rep 2016 Mar 14;6:23027. Epub 2016 Mar 14.

Bond Life Sciences Center, University of Missouri, Columbia, MO 65211 USA.

Bacteria harbored in the male reproductive system may influence reproductive function and health of the male and result in developmental origins of adult health and disease (DOHaD) effects in his offspring. Such effects could be due to the seminal fluid, which is slightly basic and enriched with carbohydrates; thereby, creating an ideal habitat for microbes or a potential seminal fluid microbiome (SFM). Using wild-type (WT) and estrogen receptor-alpha (ESR1) knockout (KO) male mice, we describe a unique SFM whose inhabitants differ from gut microbes. Read More
