Well, modern medicine in the 1400's used leaches to cure your ills ...

Just for the record, when I was a child my paediatricians were constantly injecting me with simple penicillin for bronchial infections ( bacterial colds). Vcillin, amoxycillin, still work fine for me.

So, maybe the new "super-bugs" are natural mutations that only occur infrequently but propagate very successfully?

Hospitals are breeding grounds for germs. So, don't take any antibiotics use leeches ...
