when this was posted on metafilter last year someone posted a truly excellent comment: https://www.metafilter.com/134210/Imagining-the-Post-Antibiotics-Future#5305117 https://www.metafilter.com/134210/Imagining-the-Post-Antibio...

  That was an extremely interesting comment. It would be helpful to mention that it's essentially an overview of bacteriophages, viruses which target bacteria. Describes their initial development, reasons why they aren't currently widely used, and links to more information about possible future development.

> who calls antibiotic resistance as serious a threat as terrorism What an unbelievably stupid comparison. Terrorism is mass murder turned into the sort of spectacle that causes us to massively overestimate a threat to our individual lives. If antibiotic resistance is that sort of threat, then it isn't much of a threat at all, and we can all go back to worrying about normal things such as dying from regular homicide, heart disease, crossing the road, and choking on food.
- conover 13y ago
  Maybe they meant it in the sense that we should be spending the same amount of resources on antibiotic resistance as terrorism. Or maybe it's just a ridiculous comparison.
- Qantourisc 13y ago
  No it's not as serious as terrorism. Antibiotic resistance is MORE threatening then terrorism !
  - Chattered 13y ago
    The stupidity of the comparison means that I have no idea what is meant by "threatening." In terms of individual lives, regular homicide is far more threatening than terrorism, as is choking on your next meal. Even ignoring the entwining of terrorism with politics, that already makes this a meaningless comparison. And it's not necessary, because surely we've got plenty of analogous pandemics in the field of medicine which can orientate ourselves to any looming crisis. The AIDs virus in the West is still fresh in our memory, and a far more appropriate comparison.

  Terrorism is rarely mass murder.
- magikroundabout 13y ago
  I think all that is meant is that if we are lucky, the threat posed by antibiotic-resistant strains of bacteria will be negligible in spite of media hype. Just like terrorism is. A groping comparison perhaps but a fair statement.
- rwallace 13y ago
  Unfortunately, antibiotic resistance isn't that sort of threat. It's orders of magnitude greater.

> Dukes believes, though he has no evidence, that the bacteria in his gut became drug-resistant because he ate meat from animals raised with routine antibiotic use. That would not be difficult: most meat in the United States is grown that way. To varying degrees depending on their size and age, cattle, pigs, and chickens — and, in other countries, fish and shrimp — receive regular doses to speed their growth, increase their weight, and protect them from disease. Out of all the antibiotics sold in the United States each year, 80 percent by weight are used in agriculture, primarily to fatten animals and protect them from the conditions in which they are raised. I really don't like to generalise in this way, but this sort of stuff makes me, as a European, pretty angry at the general laissez-faire attitude of the United States towards such things. You may say "The US is allowed to govern itself as it wishes, no one's forcing you to live there" - but with its heavy use of antibiotics in cattle-raising (banned in the EU - even though the US has tried to use its muscle to get the EU to un-ban it), the US is basically doing a fantastic job of fucking up antibiotics for everyone. So yes, I'm angry at the United States and its corrupt political system that means that there's almost zero chance that any of this will be fixed until it's far too late.

  Hey, libertarianism is great! Down with the state! I get actually more pissed off with libertarian cargo-culting than with current government regulation. As much as government is in bed with big corps, it's so much easier to get to an antibiotic ban with a government capable of enforcing it than with a withered state.
  - wooter 13y ago
    Drug resistant bacteria (by the articles own numbers) has killed less people per year than if you were to amortize the cost in lives of Germany's very-powerful state (and then you can add the 49-78,000,000 people killed by Mao). I, for one, am proud that Libertarians look for ways to avoid coercion and want to promote voluntary means. Bans don't work for drugs - I hope people have realized this by now... Sorry, but I find the "its such a good idea! lets force everyone to do it!" mentality quite irritating. Most solutions come from outside government. Instead of throwing huge capital at a fruitless ban, we should instead use the money on useful research. (such as the link about bacteriophages below: http://www.metafilter.com/134210/Imagining-the-Post-Antibiotics-Future#5305117 http://www.metafilter.com/134210/Imagining-the-Post-Antibiot...) Or even an educational campaign.

I will be interested to see how sexual mores develop this century. I think the "sexual revolution" will turn out to have been a flash in the pan. Resistant clap and syphilis are a growing occurrence. I expect the old order of arresting people for promiscuity to return and the new idea of privacy in the bedroom to die.

"removing antibiotics from hog raising would force farmers to spend $4.50 more per pig, a cost that would be passed on to consumers." one of those cases where savings of $4.50 a month cause extinction of human race.

Antibiotics are done, and they've been failing increasingly for at least two decades even though nobody cared to report it then. The speed of our transition to the "post-antibiotics era" is certainly our fault, but the phenomenon itself was always inevitable. Biology is an arms race, and it will always be one. In fact, biology overall is one of the worst substrates imaginable for hosting conscious entities, and that means this and many other problems may never be permanently solved. However, it's not all hopeless. There are a lot of bacterial infections that will continue to be treatable with antibiotics for some time to come. So it's not like we'll lose all of our capabilities at the same rate. It just means that gradually the number of strains that are panresistant will increase. To see what complete powerlessness over an infectious agent looks like you don't have to look further than viral infections today. The reality is we still can't do very much to treat them, so over time we'll just add significant bacterial adversaries to this list of diseases for which there is nothing else but symptomatic treatment available. This will all change, because medicine has to change. In the future, it won't be enough to hit an unspecific infection with an unspecific antibiotic. It will be necessary to analyze individual infections and their interactions with individual patients in detail - and then very specific biochemical treatments will have to be tailored on a case-by-case basis. The recent rise of monoclonal antibody drugs is a bridge to that future. We're still not knowledgeable enough, and we're still using these treatments with all the finesse of a 3-year old hammering huge lego toys together, but we'll get there eventually. We have to, it's the only hope against a lot of other diseases as well, including cancer. In the mean time, there is a lot of research that needs to be done. We're also missing the actual technologies, both diagnostic and generative machines, but the most important obstacle to overcome will probably be the culture of medicine. This culture will change only when there is enough pressure for it to change. The FDA will have to change when its primary role becomes denying treatment to people who are going to die instead of keeping the population safe. Medical professionals will change when it becomes a big factor that they lack the scientific background to effectively devise and apply advanced treatments. But first, all of these disasters will probably have to actually happen, and we're already seeing the first signs of that trend. So, there is definitely a path forward - it's not an inevitable descent into the dark ages. It's just that due to inertia and time spent waiting for basic scientific advances, there will be a period with less protection overall. Drugs may become available to plug some of these gaps, like insect-derived antibiotics, which will eventually fail too but will buy some additional time.

Does anyone think it might just be an idea to change the amount of meat we produce? When people start dying at the age of twenty and thirty of bacterial infections that are totally curable today, and gonorrhoea becomes incurable, will we think our current insouciance rational? Will it be seen as a price worth paying in order to have cheap meat? A tremendous proportion of the antibiotics we use are abused as growth promoters for animals reared for meat or their products. They are used pro-actively on healthy animals outside of the EU. Even within the EU, they are used routinely in a way that is driving us towards a post-antibiotics future. It is pretty sad to reflect that we are not able to prioritize our own health above an immediate desire to consume more meat more cheaply.
bayesianhorse 13y ago
One of the bright spots is that it seems hard for bacteria to evolve more than one resistance, and that resistances don't confer an evolutionary benefit in the absence of the specific antibiotics. There are modern techniques to avoid resistance issues. For example, as most diseases can be treated by more than one drug, switching them regularly in a hospital or practice. There are other combinations of drugs which haven't been used a lot or not even been discovered yet. It would be nice for example to trick an infection into letting go of the resistance and then attacking it with the AB.
- mnw21cam 13y ago
  > One of the bright spots is that it seems hard for bacteria to evolve more than one resistance Not sure where you got that impression. There are bacteria out there that are basically resistant to every antibiotic we have. The article even gave an example of a case where someone died because of this. > There are modern techniques to avoid resistance issues. Yes, true, and it is right that we should implement these techniques. However, until the whole world plays along there are going to be problems. If sub-clinical or too frequent doses of antibiotics are given somewhere in the world, then antibiotic resistant strains of bacteria will develop, and can be transmitted across borders.
  - bayesianhorse 13y ago
    Yes there are multiply resistant strains. But due to chance and evolution, they are spreading slowly. This is still a dangerous issue... just not as bad as if the multiply resistant bugs sprang up all over the place like single-resistant ones do.
- GFK_of_xmaspast 13y ago
  They call it "MRSA" because it's "Multiply Resistant".
exratione 13y ago
This seems like the same sort of pointless hand-wringing that attends every technology at its peak. There are any number of works in progress that could replace antibiotics. None of them have yet because they are not economically competitive. As that changes - because they either realize their potential to be much, much more effective, or because the cost of working antibiotics rises - then antibiotics will fade in favor of the next technology in line. This is what happens to every technology. Yet people seem to forget, despite the evidence all around them, that they live in a world that changes rapidly due to the fact that many, many individuals are working on new and better ways to do everything. Periods of seeming stasis to the outside observer - such as the long use of antibiotics, which is really actually a continual hectic development of new types of the single class of item - only occur because economic conditions favor them. As soon as economic conditions favor another technology, it is developed and deployed from its prototypes pretty rapidly.

  I don't think it is pointless to consider the possibility that infinite progress is not inevitable. You may have faith that science and technology will always come through, but I don't. This blind faith that things will always get better is one reason why people deny climate change. I'm not saying we give up and admit defeat, but blind optimism is foolish. Keep working on solutions, but be prepared for failure scenarios.

So is blind pessimism, people forget that by every measurable standard the human race is in a golden age (even including places like central Africa). The one thing that has lifted large parts of the world out of a short nasty, disease ridden life is science (and technology but they go together).

Reading this scares the crap out of me. Unless there are incentives to drug companies (and those who research other antibiotic tech) we could go extinct before anyone creates a solution. Yet drug companies perversely invest billions on drugs that cost $1000 a month and help solve relatively minor ailments.
TheCoelacanth 13y ago
> economists for the National Pork Producers Council estimated that removing antibiotics from hog raising would force farmers to spend $4.50 more per pig, a cost that would be passed on to consumers That is an unbelievable.

This problem has been known for a long time, though it's taken a while for it to fully emerge. I first encountered it reading Isaac Asimov's essay collection Twentieth Century Discovery, which highlights a number of the most significant inventions of the 20th century as of its publication date, in 1969 (and no, I'm not that old, I read it probably ~15 years later). http://www.amazon.com/Twentieth-Century-Discovery-Isaac-Asimov/dp/B0027WR3JU/ http://www.amazon.com/Twentieth-Century-Discovery-Isaac-Asim... The point being that natural selection is a very powerful force, and while antibiotics have proven useful, they've got very clear limits as well. And humans are an awfully large and well-connected biological niche to exploit at present.
