Ancient bacteria being revived
http://www.scientificamerican.com/articl...t-microbes

Interesting article about microbes being preserved in ice from even hundreds of thousands of years ago and "reviving" when the ice melts away, as well as the possible ramifications.

There is no way to stop this kind of thing. It's probably been happening often in nature. Besides allot of these bacteria might be poorly adapted to present conditions after their 100k year smoke break so I doubt they could do any harm when compared to the bacteria we have now which have had a chance to specialise. The way bacteria spread everywhere I doubt they would pose a new threat that we have never seen before, or be worse than MRSA or Mycobacterium tuberculosis.

Permafrost is melting in many places and there should be some interesting bacteria locked away in all that land.

I would think it is kind-of like waking up from hibernation after 100,000 years and finding out your an obsolete Neanderthal and all you family friends have evolved and moved on so you barely recognise them.

Or the other way around? current conditions not prepared for those bacteria Wink because with the bacteria that changed, immune systems changed, therefore might not be ready for something that "looks" different. Just guessing.

Human pathogens are highly specialised. They need special instructions to get around our many immune system defences. It's unlikely that it will have all the genes it needs to survive in our body. That's why it's harder to create a bio-weapon than it is to create a vaccine/cure for the bio-weapon. All current bio-weapons use an existing human pathogen as it's foundation and are modified from there.

Something totally foreign is much more likely to be killed. The diseases that decimated native populations were already human pathogens. That's why they were so deadly to those that were never exposed to it.

If human pathogens are locked away in that ice, sure we might have cause for concern. I don't know how much we have changed as a species since then though we are evolving pretty fast! Faster than previously thought.
