Germs Taken Into Space May Come Back Deadlier 137

Posted by Zonk from the just-what-we-need-down-here dept.
westlake writes "Sounds like the plot for a B-movie, doesn't it? Germs go into space and come back stronger and deadlier than ever. Except, it really happened. In a medical experiment, salmonella carried about the space shuttle in the fall of 2006 proved far more lethal to lab mice than their earth-bound source. 90% dead vs. 60% dead in twenty-six days, with half the mice dying at 1/3 the oral dose. Apparently 167 genes in the space-evolved strain had changed. The likely cause: In microgravity the force of fluids passing over the cells is low, similar to conditions in the gastrointestinal tract, and the cells adapted quickly to the new environment."

    TFS states that the deadliness is bacause the germs were adapter better to the conditions inside the body, so kill lab mice faster. Outside the lab, these germs will have to pass from host to host, and presumable in between the hosts conditions will be less like microgravity. SO, they might be deadlier, but with less rate of infection. A deadlier disease with lower infection rate might actually be less of a risk: hosts die more quickly and not enough new hosts get infected.

    Also: if the new germs are really more well-adapted (ic better at multiplying and spreading), wouldn't they have evolved like that on earth? Especially since the evolutionary step is apparently small enough to be attained by a limited colony in a very limited time?

      Not necessarily. Evolution is like a simple hill-climbing algorithm in computer programming. It blindly heads in any upward direction without any way of knowing if it will get stuck at the top of a small hill when there is a much bigger hill right next to it. It is unnatural for it to go back downhill (to weaken itself) on purpose to look for bigger hills to climb. But changes to the environment distort the landscape, in some cases turning hills into valleys and forcing life to climb back up or die out.

      So most likely the germs had their little hill turned upside down in micro-gravity and were forced to climb up to the top of a new one. Their landscape got turned upside down again when they came back down to Earth, and they ended up finding a bigger hill than the one they started on.

      Outside the lab, these germs will have to pass from host to host [...] less rate of infection. A deadlier disease with lower infection rate might actually be less of a risk: hosts die more quickly and not enough new hosts get infected.


      This is something like Rule n1 when dealing with epidemiology.
      And something that is systematically neglected when the media try to instill mass hysteria about some latest bug.

      Compare :
      - Plague : kills, but slowly, and very good at transmission - did decimate population.
      - Spanish flu : was deadly, but did spread very easily (specially at a post-war time with limited availability of medical means) - did kill quite a few people.

      With :
      - Ebola : violently deadly in an almost "B movie gore"-style, but sucks at transmission (kills to fast. The virus has almost no time to leave the host before killing it) - never became a widespread disease.
      - Avian flu : it was severe in the handful few people who caught it (although one may contest that those people were mostly in developing country and thus had limited access to medical means) BUT it's far from effecient when it comes to transmission (it's a birds' disease, damn it) one must almost live everyday with and almost sleep with chickens to catch it - hasn't been epidemic yet, and won't be, at least not until it mixes with human viruses (not very likely to happen quickly on a large scale).
      - Mad cow disease : kills slowly (brain slowly becomes a sponge) but has one of the most improbable mecanism of transmission (one must eat brain or brain derivative) - never was a widespread disease (at least outside cannibal communities).

      And same will happen with lysteria-from-outer-space : Yes, it kills mice efficiently. But basically it has changed. It has traded characteristics that where good in surviving on earth, for characteristic that are good for microgravity, and that happen to be good for the intestine too. Thus it will probably completely suck at propagating.

      It works the other way too. The outer-space-bacteria has lived and mutated in an environment without or with very few defensive system, to which it normally needs to adapt to handle them and manage to survive and proliferate. Thus the bacteria doesn't get a chance to keep it's knowledge in surviving when it come back to earth.

      It's most likely to get pwnd by the first antibody or marcophage it encounters.

      This lysteria is an exception because the microgravity environment it was evolving in was actually *closer* to the target environment (human gut) that the places where it usually lives. And then, as the first-poster pointed out, you have a bacteria that is quick to kill lab mice, but will probably suck at transmission because it has traded away its capacity to survive in normal environment.

      People are usually marvelled at the incerdible diversity that is brought by evolution. But there's another possible point of view. Whenever some species specialize into something, it's actually losing functions : at least it is losing its polyvalence and ability to survive in diverse environment.
      One may consider the human as the pinnacle of evolution given all what we managed to achieve. Or we may consider the humans as a profoundly degenerate species, that has lost its ability to survive in most environment. that is hugely dependent on resources it can't produce anymore but must hunt. We've become so much fragile and incapable biologically, that we had to develop some intelligence to be able to circumvent those short comings. As opposed to a bacteria that can just grow and reproduce in a much wider set of environment without needing to grow a pair of arms to be able to do it.
      This pessimistic point of view may be useful sometimes to explain or predict some phenomenon :
      - like mass exctinctions
      - like why the plain simple cockroaches seem to be better at surviving than mighty dinosaurs
      - like what will probably happen to the outer-space-mutant-bugs
      - like why intelligent design proponents are wrong with their fundamental concept of "irreductible complexity". It's not complexity, it's actually very weird, funny and circonvoluted side effects of something that was initially a simplification.

      Hmm. Sounds like it's about time the Intelligent Designer invested in a pair of bifocals.

      Of course, since the ID can't see to design them...

    This may be true, but remember that, from the salmonella's point of view, the object isn't to kill its host.

    The goal is to reproduce and spread. Therefore I predict this salmonella would quickly evolve back to the slightly more dormant variety, and rather quickly.

    The bacteria isn't "winning" by killing it's host faster and faster and faster. This is a disadvantageous mutation from the bacteria's point of view . One needn't worry about it "getting into the wild".

      Collateral damage.

      The Black Plague killed one third of the human population of Europe. The fleas that were the primary carriers of the disease - its true hosts - were in no great danger as a species.

    Apparently 167 genes in the space-evolved strain had changed.

    But evolution is impossible! The Kansas school board told me so. This must be another NASA conspiracy like the fake moon landings.

    • Can anyone clarify the statement about the genes. Are they actually changing (ie, a mutation) or are they simply being selectively expressed or suppressed in response to the conditions?

      Surely the article is being sloppy with its wording, yes?

  • After the meteor making people sick in Peru came up with zero re-animated corpses I was pretty let down, but NOW! Keep your fingers crossed. In all actuality I think this just goes to show we need to put a bit more faith in the space program. Some of these bacterias may come back more harmful, but surely that means its only a matter of time we find one to come back extremely helpful. That's a little quick to jump to, but still - me likey spacey.

  • What makes the salmonella become more "lethal" after spending time in space? Why does the fact that "in microgravity the force of fluids passing over the cells is low, similar to conditions in the gastrointestinal tract", allow the cells to adapt quickly "to the new environment"? *And why does adapting to space make it more lethal to earthly creatures?* It sounds like a weird coincidence that space truly is the sort of lethality breeding crucible that turns salmonella into the Andromeda Strain!
  • I mean, why Germans may become deadlier in space? do they have a secret base on the moon?
