The Human Microbiome and Gut Microbiota
The human microbiome is defined as the microbial community (bacteria, fungi, viruses and protozoa) present in the human body. The human microbiome plays very important roles in the maintenance and development of the immune system and metabolism among other body functions.
The densest and most diverse microbial community has been found in the human gastrointestinal tract.
Large governmental research initiatives including the Human Microbiome Project in the U.S. and the MetaHIT Project in Europe accelerated research on the human microbiome. Scientists are quickly learning the details of how microbial populations interact and the roles they play in health and disease.
