How does finishing the prescription ensure that all the bacteria is killed and that there are no surviving or remaining bacteria? Have always been told that finishing the prescription does this but never how

You have bunnies in your yard, eating your veggies! There are a lot of them! You start trapping and shipping bunnies off to the other side of the country. It’s working! Your veggies get eaten less and less! Eventually you’ve captured most of the bunnies, and your garden is fine, so you stop trapping.

But there are a few bunnies left, and they have more bunny babies, who also have more bunny babies. In a very short time, your entire garden is being eaten again!

So next time, you trap the bunnies, but KEEP ON TRAPPING even when your garden is *mostly* OK. You trap, and trap, until you are sure EVERY bunny in the area is gone. Now your garden is ok, and next week, next month, hopefully even next year, your garden is still safe from bunnies.

That’s antibiotics. If you stop when you feel better (as in stopping catching bunnies when your garden seems to not be eaten up much), the last bit of bacteria (bunnies) will reproduce, and be just as big a problem as they were in the first place in a short time. But if you keep on taking your antibiotics (trapping bunnies) you can get rid of every last one, and they won’t reproduce and return.
