A series of groundbreaking studies [sciencedaily.com] have revealed that what we have always thought of as individuals are actually "biomolecular networks" that consist of visible hosts plus millions of invisible microbes that have a significant effect on how the host develops, the diseases it catches, how it behaves and possibly even its social interactions.
...
In this case, the parts are the host and its genome plus the thousands of different species of bacteria living in or on the host, along with all their genomes, collectively known as the microbiome. (The host is something like the tip of the iceberg while the bacteria are like the part of the iceberg that is underwater: Nine out of every 10 cells in plant and animal bodies are bacterial. But bacterial cells are so much smaller than host cells that they have generally gone unnoticed.)

Microbiologists have coined new terms for these collective entities -- holobiont -- and for their genomes -- hologenome. "These terms are needed to define the assemblage of organisms that makes up the so-called individual," said Bordenstein.

There may really be something to this. Other recent research has focused on the role that microflora play [nature.com] in obesity and other aspects of human health. What do you fellow "holobionts" say, does it disturb or comfort you to think of yourselves as a walking constellation of bacteria?
