Tending the Bodyâ€™s Microbial Garden
For a century, doctors have waged war against bacteria, using antibiotics as their weapons. But that relationship is changing as scientists become more familiar with the 100 trillion microbes that call us home â€” collectively known as the microbiome.
This new approach to health is known as medical ecology. Rather than conducting indiscriminate slaughter, scientists want to be microbial wildlife managers. No one wants to abandon antibiotics outright. But by nurturing the invisible ecosystem in and on our bodies, doctors may be able to find other ways to fight infectious diseases, and with less harmful side effects. Tending the microbiome may also help in the treatment of disorders that may not seem to have anything to do with bacteria, including obesity and diabetes.
