Preface to the human microbiome in urologic health and disease

We are very pleased to present this special issue of the Annals of Translational Medicine, “The Human Microbiome in Urologic Health and Disease.” This issue developed from the Basic Science Symposium of the same name sponsored by the American Urological Association (AUA) Office of Research at the Annual meeting of the AUA on May 6, 2016. Speakers who presented at that symposium comprise the invited authors for this issue.
