Ethical issues in microbiome research and medicine

The human microbiome is the collection of bacteria, viruses, and fungi that live on and in the human organism's skin, mucosa, and intestinal tract. Re-examining commonly accepted ethical standards from the perspective of this new area of research provides an opportunity to reassess our current thinking about research regulations as well as the importance of some principles and distinctions. In this commentary, I explain ethical issues illuminated by research on the human microbiome related to personal identity, privacy, property, research ethics, public health, and biobanks.
