Discovering my microbiome: “You, my friend, are a wonderland”

Carl Zimmer in his excellent blog, The Loom:

Ileana-navel-in-Saree Some people get a thrill from getting their genome sequenced and poring through the details of their genes. I’m a bit off-kilter, I guess, because I’m more curious about the genomes of the things living in my belly button. And let me tell you: it’s a jungle in there.

I first became curious about my navel in January. I was in Durham, North Carolina, to attend a meeting, and as I walked out of a conference room I noticed a cluster of people in the lobby handing out swabs. They were asking volunteers to stick the swabs in their belly button for the sake of science. Our bodies are covered with microbes, and scientists are discovering weirdly complex patterns to their biodiversity. From fingers to elbows to chin to forehead, different regions of our skin are dominated by different combinations of species. But the bellybutton remained terra incognita.

I happily donated my microbiome to the study, which is being conducted by Jiri Hulcr and Andrea Lucky, two post-doctoral researchers in the laboratory of Rob Dunn at North Carolina State University. After a few weeks, Hulcr sent me a photo of a Petri dish in which some of the bacteria from my bellybutton were thriving. Then Hulcr and Lucky got down to the serious work of identifying the species in the navels of their volunteers (90 and counting).

Yesterday, Dunn sent me a spreadsheet detailing my own results. “You, my friend, are a wonderland,” he wrote.
