There isn't anything about that microbe that you can't figure out. If we didn't have the protease enzyme that was crystallized and then used as a framework to design a drug that was targeted toward the protease, we would never have been able to do this. There is a constant tension between the survival of the human species and the survival of microbes. Certainly, the end result is that both can exist and do exist. But the unifying theory is that there is more than just human life around.
Microbes are an important part of our existence.
