And you have sources? Because last time I checked this was the worst way of doing it, as you leave enough bacteria to try and mutate into resistivity.
If you already had resistant bacteria, taking antibiotics wouldn't heal you for long anyway, tried it first hand a few months ago.
We're below reproduction rate in most parts of the world, and likely will fall below in the rest of the world during this century, so we're already in the 'find out' era :(
