Fale analogy, there is no such thing as a single stress in the real world, it's all multiples. And in addition (no pun intended) your numbers are illustrative, otherwise there woul dnever be any successful bactrerial adaptation ever. Finally, how many successful adaptations are necessary? Answer - only one that lives to reproduce. Your same mathematics grows that survivor into trillions because it can defeat what is attacking it.
I'm not saying this isn't probably a success. I just get cheesed off when it totuts itself as perfect. And that's coming from the actual science foundation, not even the press, so it's a million times more offensive.
But look WHERE it's from - East Anglia, the hockey-stick climate change liars. So what IS it with that place?
Oh. I see. In your world no one ever takes most of a course of a single antibiotic. Interesting. Good to know. Thanks.
