This combines human nooks and crannies, germs, and a reference to a John Mayer song. In short, it is designed for dedc’s viewing pleasure:
So perhaps my belly button is especially well-defended. Still, I can’t help but wonder if I ought to scrub it with some steel wool. There are some very exotic things in there. Only a small fraction of my belly button bacteria were common among the other 89 volunteers. The microbes I share with most other volunteers tend to be ordinary skin dwellers that are typically harmless (although sometimes they can turn nasty and cause problems ranging from acne to staph infections).
But out of 53 species, 35 were present in only 10 or fewer other volunteers. And 17 species in my navel didn’t show up in anyone else. In the column for notes in Dunn’s spreadsheet, he’s annotated these species with scientific descriptions like “weird one” and “totally crazy.”
Several species I’ve got, such as Marimonas, have only been found in the ocean before. I am particular baffled that I carry a species called Georgenia. Before me, scientists had only found it living in the soil.
When I learned this, I emailed Dunn to let him know I’ve never been to Japan.
“It has apparently been to you,” he replied.
While I may be a bit of an outlier in the belly button department, I’m not a freak. Among all 90 belly buttons Dunn and his colleagues have studied so far, they have found 1400 species of bacteria, a number of which have never encountered on human bodies before.
