Alligator Blood May Be Source of New Antibiotics

esocid writes "Biochemists from McNeese State University have described how proteins in gator blood may provide a source of powerful new antibiotics to help fight infections associated with diabetic ulcers and severe burns. This new class of drug could also crack so-called 'superbugs' that are resistant to conventional medication. Previous studies have showed alligators have an unusually strong immune system; unlike humans, alligator immune systems can defend against microorganisms such as fungi, viruses, and bacteria without having prior exposure to them. Scientists believe that this is an evolutionary adaptation to promote quick wound healing, as alligators are often injured during fierce territorial battles."

      What it boils down to is that this reasearch is going to end up killing alligators by making immune germs so that we can raise pigs and chickens under worse conditions. That's what we are talking about really.

      Humans need newer antibiotics because we wasted them growing pigs and chickens, and reducing the puss in milk from overproducing cows. Also, even if this 'cures' HIV the benefit is not so much in saving lives but more in protecting a social order that allows it to spread.

      This will certainly result in a sad reflection on our society, that we would contribute to the destruction of animals that have been around for hundreds of millions of years. So we can have our pork sandwich for lunch for $0.50 less. But hey since we're giving a collective 'fuck you' to the world anyway, why not?

      Whoa, man. We're talking proteins in the blood...after the initial research it will probably be more practical to produce them synthetically.

      I take it you're not a fan of medical research as it runs opposed to the natural order of things. But if we are in relative control of our own evolution at the moment, why should we allow our species to disappear? If the whole point of life is to propagate, and we have mechanisms in place to accomplish this basic task better, wouldn't it be against nature to do the opposite?

      I find your comment interesting for another reason: you typed your comment on a computer, right? One of the byproducts of modern eco-destructive society?

    The ability to heal quickly and fight off almost any infection would be a huge adaptation for any animal even without the territory battles. The fact that alligators are one of the few (only?) animals to evolve this adaptation indicates that it comes with a hefty price.

    The question is, can we leverage this adaptation for ourselves without incurring the price? If the price is energy expended to produce the ultra efficient immune system, that's fine; but if the price is directly tied to the effects themselves this may prove worthless.

    Gators/Crocs are famous for having not changed much since the time of the dinosaurs.


    I wonder if since they have a very strong immune system that kills viruses etc so well, if they have not denied themselves the opportunity to incorporate useful viral dna and bacterial plasmids into their own dna. It would be interesting to see if they have a different amount of viral origin genes in their genomes than other animals.

      I can't help but wonder if they haven't changed since the age of the dinosaurs *because* of their strong immune system. Viruses cause a lot of DNA mutations for natural selection to work with. If your immune system is efficient at killing viruses, that cuts off an entire avenue for helpful mutations to enter the genome. Their source of mutations has been reduced to cosmic rays. Overgeneralized, but I hope you get the idea.

      Maybe we should start looking at other dinosaur-era lifeforms and seeing what's in their immune system.

    My only concern with this type of approach is how hamstrung will we get when the first protesters arrive?


    Possibly somewhat, but not as much as if the protesters hadn't been there all along to make sure the species did not become extinct, or too rare to study.

    You're probably too young to remember this, but alligator skin used to be quite stylish for handbags, shoes, wallets and the like. Wild populations can provide a sustainable source of goods like this so long as people don't take so many animals that the equilibrium breaks down and the population crashes. However, that's pretty much the inevitable course of events ever since society reached a sufficient technological level to respond to market opportunities with tools that make resource extraction orders of magnitude faster (and thus more profitable).

    You, as an alligator hunter, may be smart enough to know you'll make more in the long run by sustainable harvesting, but if your competition is sufficiently inbred, this sounds like hifalutin nonsense to them. When the idiots are making more money than the smart people, the near-idiots emulate the idiots, and pretty soon the people acting intelligently are the only ones who aren't in on the bonanza. At that point the intelligent choice is to act stupidly, because you maximize your long term return by grabbing a share of the breeding stock before even that is liquidated.

  9. Cost of Complexity is a Myth by eldavojohn · · Score: 5, Insightful

    There was very recent research that was quite extensive that showed this cost of complexity in evolution is a myth. I don't know why you think it has to come at a cost, it just so happens that alligators needed it to live in their conditions and with their temperaments.

    You can sit here all day and question why we don't have some of the obvious advantage traits that any other animal has and the answer is simple: we didn't require it. If humans needed it and didn't have it, we wouldn't be around.

    Explain your logic on why this must come at a price? The random evolution happened in alligators and may be present in other animals (or extinct relatives).

    There are already decent protections for legal hunting gator, and this may increase the pressure against poaching.

    I am a Muslim, and I can say that in Islam, there is a blanket overruling of all prohibited substances in the course of saving a life, such as eating pork in starvation situations or deriving medicine from alcoholic sources. Deriving medication from pigs would be allowed, and so too would medicine from alligator blood.

    Most opiate analgesics and anaesthetics are, for example, prohibited under the intoxication rule (the one that prohibits alcohol), but are allowed in medical situations. Same for alcohol used in field treatment of hypothermia and other emergency situations.

    I'm not sure about the Kosher rules in Judaism, but in Islam, any substance of medicinal value is permitted if necessary for the health of the patient.

    This rule is conscience based I guess, for all of you thinking of that Simpsons episode where the blind guy was smoking weed for "medicinal purposes".

    As far as I understand, the same is true in Judaism. The "laws of kashrut" are overruled when one's life or health is at stake.

    It may be helpful to add that Orthadox Jews traditionally keep kosher on a voluntary, not compulsory, basis. That is, the rules are followed in order to honor god, not because there is some terrible consequence or threat involved if they do not do so. It is not a "keep kosher or go to hell" kind of thing.
