The more you use an antibiotic, the more you expose a bacteria to an antibiotic, the greater the likelihood that resistance to that antibiotic is going to develop. So the more antibiotics we put into people, we put into the environment, we put into livestock, the more opportunities we create for these bacteria to become resistant. …We also know that we’ve greatly overused antibiotics and in overusing these antibiotics, we have set ourselves up for the scenario that we find ourselves in now, where we’re running out of antibiotics.
We are quickly running out of therapies to treat some of these infections that previously had been eminently treatable. There are bacteria that we encounter, particularly in health-care settings, that are resistant to nearly all — or, in some cases, all — the antibiotics that we have available to us, and we are thus entering an era that people have talked about for a long time.
For a long time, there have been newspaper stories and covers of magazines that talked about “The end of antibiotics, question mark?” Well, now I would say you can change the title to “The end of antibiotics, period.”
We’re here. We’re in the post-antibiotic era. There are patients for whom we have no therapy, and we are literally in a position of having a patient in a bed who has an infection, something that five years ago even we could have treated, but now we can’t.
...
So methicillin-resistant Staphylococcus aureus, or MRSA, for a lot of people is the first time that they had really encountered one of these highly drug-resistant bacteria.
...
We were seeing it in young people who were athletes, who were young football players who had serious infections, who died of these MRSA infections which had previously been limited to hospitals.
We saw outbreaks in schools. We saw outbreaks in health clubs. And what most of these people were getting was something very different from what we saw in hospitals.
