Our Foot is Home to 200 Species of Fungus

There's a fungus among us - actually, scratch that - there are many more fungi living on our body. More then 200 different species in our feet alone:

In the first study of its kind, a US team catalogued the different groups of fungi living on the body in healthy adults.

A team led by the National Human Genome Research Institute in Bethesda, Maryland, sequenced the DNA of fungi living on the skin at 14 different body areas in 10 healthy adults.

Samples were taken from the ear canal, between the eyebrows, the back of the head, behind the ear, the heel, toenails, between the toes, forearm, back, groin, nostrils, chest, palm, and the crook of the elbow.

The data reveal that fungal richness varies across the body. The most complex fungal habitat is the heel, home to about 80 types of fungi. The researchers found about 60 types in toenail clippings and 40 types in swabs between the toes.
