Bacteria and viruses mutate and some mutations confer resistance to drugs. Those survive.
MRSA didn't "lie dormant" - it evolved.
Gee, how did you work that out?
I will have to tell that idiot that told me that inside our body we have all kind of germs ready to express themselves as the body weaken that he was wrong.
He also told me that mutation is a tricky concept.
It works like the water in a river.
When there is too much water the river flood in a certain place creating a problem (in our case when the cause of the disease can not be contained then it will be expressed in the form of a particular diseases and when the cause is not contained in a different place it will cause a different disease).
So mutation is not that the bacteria and viruses mutate but that the cause of the disease find a different way to express itself as the reasons are different.
Anyway good luck with your study in biology.
