To be sure, antibiotics kill off organism that are not resistant, and fail to kill off those that are, and as a direct result the resistant organisms are a higher percentage of the total over time. But the antibiotics didn't create the resistance, nor increase the numbers of the resistant organisms.
Put it this way: Let's say you start with 100 resistant bacteria and 2000 non-resistant ones. At the end of a certain period of time they would multiply by a factor of (say) a million, at which point you'd have 100 million resistant bacteria and 2 billion non-resistant. Or, if you use antibiotics freely, you have 90 million resistant bacteria (assuming they're slightly susceptible to antibiotics) and 200 thousand non-resistant (assuming you can't get 'em all). So sure, the percentage of resistance went from 4.8% to 99.8%, but you're still better off by having eliminated 95.7% of the target organisms.
So can someone, akatow or someone, tell me what I'm missing?
