Man’s relationships with bacteria exists in a fine balance. Within and on our bodies are more bacteria that we know what to do with. They help us live and function and without them we would be lost.\nBut our bacterial friends can turn on us quickly, and over the years we have helped them become better and live longer. In fact we have done so well that we are running out of things to use when we don’t even want them around anymore.
