The Marvelous

The microbiome refers to the genetic material of literally trillions of microbes – bacteria, fungi, protozoa and viruses – that live inside and on the human body.

Scientists have called it the second genome, and in fact, the number of genes in the microbes making up one person’s microbiome is 150 times greater than the number in the human genome. All humans are 99.9% similar in terms of their host genome, yet we can be 80-90% different in terms of microbiome.

Microbiome by the Numbers

Gut Feeling

Each person’s microbiome is also constantly changing and evolving, and it has long been speculated and explored that this balance of microbes has a direct impact on differences between a healthy state and the presence of inflammation or disease, including certain cancers.

Over the last decade, there has been rapid acceleration in scientific understanding of the composition and functions of the gut microbiota. Today, around 200 companies are focused on understanding the human microbiome and its linkage to areas including infectious diseases and oncology, with the goal of identifying therapeutic targets.
