Our gastrointestinal system (GI tract) contains about 100 trillion microorganisms - mostly bacteria with a few fungi, protozoa, and viruses thrown in. That number is ten times the number of cells that make up our body. The roughly 1000 species of microbiota and their vast array of genetic material (about 10 - 100 quadrillion genes) are collectively known as the microbiome.
