Abstract

Microorganisms are a fundamental part of life and essential to the mammalian digestive tract. Evolution has incorporated a vast number of intestinal alterations in morphology and physiology among the animal kingdom. When intestinal conditions change it alters the microbiota in the gut and digestive process. For certain chemical compounds to be broken down and absorbed, microbes with that ability must be present. Microbiota in the gut can also cause diseases such as irritable bowel syndrome (IBS) and colon cancer. One must maintain microbial diversity in the gut to stay healthy. To help improve and withhold diversity in the gut one should consider diet, exercise, probiotics, and retaining overall health. Someday researchers hope to use gut microbes as biomarkers for human health.
