A recent study compared the microbial diversity of three US office buildings.
Using cell counting and ribosomal RNA sequencing, the authors composed the above image to represent the number and diversity of the most commonly identified microbes.
As quoted in the study:
[H]umans move through a sea of microbial life that is seldom perceived except in the context of potential disease and decay.” (Feazel et al.)
I’m off to clean my desk (again).
