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."

      Alcohol is a mild vasodilator, so it would reverse your body's major defense against cold, restricting blood flow to the extremities/surface and keeping a pool of warm blood in the core. Even after the person is in a warm environment, vasodilation is dangerous because the extremities/skin are cold, the blood there is cold, and suddenly moving a bunch of warm core blood through the cold extremities and back will lower the core temperature further. The teaching is that this could kill a patient by pushing their core temperature down suddenly, past the critical value. When resuscitating a severely hypothermic patient, you always warm from the inside out, and you never give vasodilators.

I believe the real root of your concern, which I share to some degree, is that oftentimes people will be quick to graft on an explanation based on evolutionary theory to any peculiar feature of an organism, without any testing. Thus, one could conceivably concoct several different interpretations based on evolutionary theory of the origins of any feature of an organism.

    However, and this is the key point, just because one can come up with an arbitrary interpretation, does not mean that an explanation grounded in evolutionary theory is incorrect. A more disciplined and principled approach would be needed, that's all.

    Since every organism is subject to selection pressures, evolutionary theory indicates that any structural or functional feature of an organism arose as a result of conferring some benefit to the organism across many generations.

    Or to put it another way, if a perplexing feature of an organism is not attributed to evolution, to what can it be attributed? Evolution is precisely a way to account for such features.

    Be wary of doubting this ... that way lies creationism!

    The first single cell didn't have a powerful immune system. Alligators do. Somewhere along the way the branch of life leading to alligators, they evolved a powerful immune system. Why does that characterisation bother you?

    Perhaps I misunderstood you, and you were reacting to the common tendency for the news to report some simplistic off-the-cuff guess as to what environmental pressure led to a certain feature evolving. In this case, territorial fights=super immunity. I heard a story on the news this morning about how less sleep leads to increased feelings of hunger and the reporter added, 'this makes sense in evolutionary terms because clubbing rhinos for food all day takes a lot of energy and increased hunger will help replenish that energy' huh? wtf?

  17. 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).

      I'm not saying that the complexity of the immune system implies a cost to the organism, I am saying that this adaptation is so ridiculously advantagious that there must be some cost or it would be much more common (Of course, this conjecture falls apart if the adaptation is more common than the article implies). And yet, here you and I are with opposable thumbs and an increased Broca's Region of our brain ... why don't other animals have these ridiculously obvious advantages? Evolution is random and only reacts to the environment of the organism.

      Don't believe that this adaptation is that advantagious? Infections deseases are responsible for 20% of human deaths, second only to heart disease; and that is even with modern antibiotics. A death rate of 20% is inflated because we know how to circumvent so many other forms of death. I'm sure prior to civilized humans, we were killed by many many other things. Not to mention that low death rates can lead to famine and ecosystem failure. How do you know we're not dooming the earth by ensuring everyone lives to age 70 and has 2.4 children? The human population is not kept in check the same way it used to be because of modern antibiotics.

  18. There may be no cost by Devin+Jeanpierre · · Score: 2, Insightful

    The fact that alligators are one of the few (only?) animals to evolve this adaptation indicates that it comes with a hefty price.
    There is no such indication. There may be a cost, but that's not indicated by the evidence. It may just be that most/all other animals didn't have the specific circumstances that would start a chain of mutations leading to this. It could simply be that alligators are far more likely to get injured, and therefore when this mutation occurred, it much more likely to survive than it would be in animals without such a high rate of (possibly survivable-- if you're trapped, you're trapped, no matter if you could recover from the injuries or not) injury. It just might be that simply needing a better immune system isn't enough to make this evolve, or it might be that this effect is from a combination of genes that individually mainly benefit healing. I am not an evolutionary biologist, or a biologist at all, but I think that it is premature to conclude that alligators are of the few to have this due to some cost. Especially important is that, since we only just discovered it in alligators, it may exist more widely than just a "few" animals.

It turns out they're very similar to thorns on some trees in Africa, which evolved to minimize predation by elephants. Well, it turns out these trees from New York evolved these spikes to fend of mammoths, though it seems like a silly waste of energy now.

    The trees that didn't have the spikes were all eaten. The alligators who couldn't heal quickly all died. That's evolution for ya.

Since last 27 years Institute of Immunology and Experimental Therapy of Polish Academy of Sciences (located in Wroclaw) have been involved in curing about 1500 people with suppurative bacterial infections, in which a routine antibiotic therapy failed.

    http://www.iitd.pan.wroc.pl/phages/phages.html

    This is not a secret thing, so most likely all important people involved in that kind of science (MRSA infections) are aware of this kind of therapy.
    Why in other countries (except Poland) is that treatment still not known and not available? Lot of people is dying due to 'superbugs'! MRSA infections alone are responsible for more deaths in the U.S. each year than AIDS!
    Why not to let people to try this still EXPERIMENTAL therapy?

    Maybe the health care industry got to big inertia or doesn't care or just prefer to cure people with super-expensive brand new antibiotics instead of something relatively cheap.
    Is they business case more important then people health or life? They just want to make money instead of curing people?

    The final conclusion is that we shouldn't expect anything spectacular regarding 'gator immune system'. Other treatments are already available but simply ignored.

    It could also be that the changes required to end up with an immune system like that are incredibly complex and may involve steps along the way that are not evolutionarily advantageous in most species, so the necessary sequence of evolutionary steps was not completed in most species.

    The alligator does not seem to be entirely unique in this.

    In my Emerging Infectious Diseases class, we learned that the tiny ticks that spread the Lyme disease bacterium are known to bite and feed on the blood of the western fence lizard. An interesting side effect of this behavior is that the blood of the lizard apparently clears the ticks' guts of Lyme bacteria. So this immune adaptation is apparently present in a number of lizard species.

    Think, also, of the Komodo dragon, which walks around with a poisonous soup of microbes in its mouth at all times -- in fact, it actually uses this disease cocktail as an offensive weapon.
