Eli5 why not finishing a full course of antibiotics causes resistant strains of bacteria

1.13K views

My understanding is that the antibiotics won’t kill the random mutant bacteria anyway, so doesn’t killing off all the susceptible ones just allow for more room for the mutants?

Does it have to do with more base bacteria getting the chance to mutate? A specific resistance has to be pretty rare right? Or will you have multiples of the same mutation in a “colony”?

I do the entire course of treatment and so should everyone but…..

I’ve looked for evidence that there is a scientific basis for a “course” of treatment but it is just folk wisdom.

That isn’t to say that there isn’t merit to it but what I’m saying is that the length of treatment is entirely arbitrary.

Someone at the beginning of antibiotics said a week should do it and now it’s set in stone.

No double blind experiments. Nothing.

No tests or evaluations for different antibiotics against different gram negative bacteria. Nothing.

Most stuff in medicine is a WAG but their WAG is probably ok.

As an engineer sometimes I think there is very little diff between med and voodoo that’s why I try and avoid at all possible.

And I have a few friends who are in that trade.
