Human microbiota. Microbes exist in niches throughout the human body. A healthy microbiota contributes to the overall health of the host and, conversely, when imbalanced can cause health complications. Microbial influences on disease states and the relative abundance of host-associated bacterial genera for different regions of the body are depicted. The most abundant species present in distinct locations of the digestive tract. The data presented are estimated from References 1 and 147–150.
