Ecology of the Human Body

People don’t normally associate the human body as an ecosystem filled with communities of microbes but research suggests that our body harvest a vast number of micro-organisms that help with digestion and may even cause disease. One particular cavity that carries a large number of these micro-organisms is the oral cavity. There is an immense number of mircro-flaura that pass through saliva and into our gastrointestinal tract. From the 20th century, oral hygiene has been a crucial tool in minimizing diseases and aiding in the effort for public health. However, even today, many diseases including cardiovascular disease, pancreatic cancer, colorectal cancer, rheumatoid arthritis, and preterm birth have been attributed to distal infections. This is an extensive field that poses a lot of questions regarding public health to a spectrum of healthcare professionals and biologists.
