We may not see them, but we need them. An estimated one hundred trillion microorganisms inhabit the human body.  This includes bacteria, fungi, viruses, protozoa and mites.  There are gut, skin, respiratory, bone and even nervous system microbiomes – and this may be an incomplete list.  We are only beginning to understand how these microbial communities impact health and disease. Dr. Yoon Cohen has started a web site called Skin Microbiome that will serve as a repository for the emerging literature on this subject.  Disorders such as acne, atopic dermatitis, perioral dermatitis, psoriasis, rosacea, seborrhea, seborrheic dermatitis, skin ulcers and many more appear to be caused or exacerbated by an … Continue reading

The human microbiome is the collection of microorganisms (such as bacteria viruses and fungi) which live on and inside humans (on the skin, in the saliva and mouth, in the eyes, and in the gut and the rest of the gastrointestinal tract). Foreign microbes outnumber human cells in the body a wide margin; humans have about 100 trillion cells, and carry ten times as many microorganisms in the intestines alone. We know that some of these organisms are useful for humans. However, most have no known effect; they are just symbionts and are referred to as the normal ‘flora.’ Studies in 2009 asked whether our health is damaged if we reduce this biota (collection of … Continue reading
