Taking antibiotics when you don't need them.
Ok, so here is what I used to think. If you take antibiotics when you don't need them it will increase the amount of antibiotic resistant bacteria and damn those doctors for over prescribing medication.
Now here is what I am learning in my microbial genetics class. Its been proven that genetic mutations happen in bacteria in the absence of selection and are not a response to selection.
Hmmm. So what you are telling me is that bacteria can and will become antibiotic resistant regardless of how many antibiotics we take.
What does still hold true is that when prescribed and antibiotic, you must take all of it!!! Otherwise you are killing off bacteria with no mutations and leaving bacteria with the mutations alive so that they can continue to reproduce and spread their antibiotic resistant genes.
Anyone else know anything on the subject?
