|
an effort is now underway to utilize ? to identify the microbial profile inside and on humans. The name of the project is the ? and the aim is to collect genetic sequences in the gut, respiratory tract, skin, etc. to determine which microbes are there, even when they can't be grown in the lab.

Biota
|
|
|
? infections are those caused by biota that are already present in the body.
