Global Biological Experiment Generates Exciting New Results 340

New submitter hoboroadie writes "Scientific American Magazine says antibiotic-resistance genes have moved from the incubators of our hospitals and factory farms, and are spreading through diverse species in the wild. Resistance genes have been detected in crows, gulls, houseflies, moths, foxes, frogs, sharks and whales, as well as in sand and coastal water samples from California and Washington. This stuff is getting more and more like a Hollywood script everyday, n'est ce pas?"

    We had a half a percent higher profit margin on cattle for a couple decades. That's totally worth having permanent incurable deadly diseases. Tragedy of the commons sucks balls, and time and again, it turns out that the "invisible hand" won't develop any solution to it.

          First of all, the regulation of the health care industry is to the side of this issue. The largest driver for resistance is the over-use of antibiotics in non-health care related fields, like industrial agriculture, and hand soap.

          The market forces here are the desire for higher meat production (ie, more profit!) as well as the marketability of antibiotics to consumers that don't realize that you don't need or want antibiotics everywhere.

          Where the market forces completely and utterly fail is that the very high cost of widespread antibiotic resistance is NOT being directly felt by the industries that are using them the most. It is in fact a very nice example of where pure capitalism fails - large, long-term, external costs are not felt by the people making short term profits.

            Horseshit. Complete and utter horseshit.

            Individuals do not necessarily exhibit fully rational behavior (in fact quite seldom do), and individuals will always try to get 'more better' for themselves -- because people are irrational selfish bastards.

            So, if I decide that what is better for me is to take away what you have, that isn't better (or even good) for the group if we depend on one another. Very often, what's good for an individual is detrimental to the group if the individual is utterly selfish or shortsighted -- like eating all of the food now and leaving none for later. Taking fresh water, bottling it and selling it isn't good for anybody except the ones selling it -- and once it's all gone, we're all fucked. But, for the short term, it was beneficial for some individuals to do what is best for them, and the group suffers.

            The prisoners dilemma [wikipedia.org] demonstrates that if everyone does what is strictly in their own best interests, everybody loses.

            Capitalism just tries to take the things which are shared resources, and make sure someone gets to it first and claims ownership of it. And when we're talking about our environment and ecosystem, it impacts all of us. And in the end you get the selfish decisions of a few impacting everybody else.

            People like to pretend that 'the market' will solve these problems, when in fact it's mostly a race to the bottom where every sociopath around grabs as much as he can, to the detriment of those around him.

              A resource can't be shared if no one claims ownership of it. So is your solution that no one is allowed to claim ownership? Or is it that the State will claim ownership?

              In a system where property is not allowed, what is the motivation to be productive? An interest in the common good? That demands altruism. Without individual moral principles, the common good fails... and look, here is the tragedy of the commons again.

Private ownership helps, but it isn't essential.

      First: it's not a free market. Not in the US, anyways. The FDA and CDC and whatnot regulate what antibiotics can be used in animals... or, at least, in food animals (which is where most animal antibiotics are used). Secondly, the antibiotics used (and therefore the resistances generated) are different in animals than in humans, in large part for exactly that reason: we don't want the widespread usage of antibiotics in animals to result in human diseases becoming much more resistant. And finally: permanent and incurable is incredibly unlikely. Antibiotics resistance has an energy cost associated with it: it takes more effort to be antibiotic resistant than not. That means, absent the use of antibiotics, the resistance will naturally be selected against and fade from the population over time. And even then, there are many classes of antibiotics. Resistances are only to one or two of those classes (although a bacteria resistant to all of them is truly terrifying, it requires even higher energy cost for the bacteria).

      Antibiotics resistance is a major problem on multiple levels, but the problem of resistant strains in humans is due to usage of antibiotics in humans (you know, to save people's lives), not the usage in animals. Resistant animal diseases is also a major issue, of course, because they're a huge part of our food supply, but not so much because we're worried about human diseases becoming resistant to human antibiotics because of antibiotics usage in animals.

        Actually, this (often) isn't the case.

        It's obvious in theory that antibiotic resistance may or may not have a cost associated - but without any selection pressure, whether the resistance evolves is down to luck. Add the antibiotic and the selection is driven but remove the antibiotic again and the selection pressure doesn't need to be back towards the original state.

        What is perhaps more surprising is that reversion to antibiotic susceptibility in the absence of the antibiotic is relatively rare - what actually tends to happen is that there are other mutations driven by the absence of the antibiotic rather than loss of the resistance.

        The third one is interesting in that it says that sometimes antibiotic resistance can evolve due to a selection pressure unrelated to the antibiotic. If antibiotic resistance was very costly then you wouldn't expect to see this.

    If you use something that kills of the weak members of a given entity over a period of time the result will be the surviving members will become strong. Darwinism is brutal and efficient like that whether you want it to be or not. In this case by over using antibiotics everywhere from handsoap to feed for cows we have resulted in the saturation of the environment. The result was inevitable and it really is a case of we did this to ourselves.

I still refuse to use hand sanitizer or anti-germ wipes and I don't expect every surface I touch to be disinfected. Some of that has changed as I have gotten older (I shower at least once a day and by most peoples' standards I'm quite "clean"), but I'm willing to bet that my "unclean" behaviors in the past and my lack of fear of germs and dirt and grease under the nails explain why I very rarely get sick (once a year maybe) and even more rarely stay sick longer than a few days.

      I read somewhere that there's a theory about auto-immune diseases being a result of humans no longer having parasites and infections. The theory was that the immune system has nothing to do and "gets bored." The possible solution is introducing a limited amount of relatively benign parasites.

    The article makes it sound as if the crows are themselves acquiring genetic modifications giving them resistance to antibiotic compounds. However, it is the bacteria inhabiting the crows intestine that have acquired the antibiotic resistance genes, not the crows themselves. The article also suggests that antibiotics dispensed in hospitals are somehow a major factor when, in fact, the quantity of antibiotics dispensed in factory farms surpasses the quantity dispensed for human medical needs by orders of magnitude. If antibiotic resistance leads to increased human mortality, blame the steak on your plate, not the poor fellow down the street having surgery at the hospital.
