At what point did the human microbiome become such a hot topic?
When it was shown that babies born by Cesarean section are colonized with different bacteria than those born vaginally? With the cardiovascular studies of microbial byproducts of meat digestion? With the advent of fecal transplant as a proposed treatment for Clostricium difficile infection?
The bacteria and other microbes that live within the human body are thought to influence not only digestive health, but metabolic and autoimmune diseases as well, possibly even psychiatric and neurodevelopmental disorders. The field is being propelled by next-generation sequencing technology, and Nature had to publish an editorial guarding against hype (a major theme: correlation is not causation).
At Emory, investigators from several departments are involved in microbiome-related work, and the number is expanding, and assembling a comprehensive list is becoming more difficult. Researchers interested in the topic are planning Emory’s first microbiome symposium in November, organized by Jennifer Mulle (read her intriguing review on autism spectrum disorders and the microbiome).
Microbial genomics expert Tim Read, infectious diseases specialist Colleen Kraft and intestinal pathologist Andrew Neish have formed an Emory microbiome interest group with a listserv and seminars.
