Initially the team looked for a relationship between pool conditions and microbe population. But while the populations of different viruses fluctuated wildly pool conditions stayed the same. The researchers set out to determine how migration to pools miles away might occur. Since subterranean water temperatures are so high underground migration seemed unlikely. Strangely viruses thrived in pools even if their chosen hosts were relatively rare. Sulfolobus viruses are not hearty. Most survive only a few hours in the acidic water outside a host. The viruses might also be capable of infecting a wider range of microbes than researchers now know. To reproduce these viruses need to leave their hosts. Then they re entering a really hostile environment. A greater understanding of the significance of viruses in Yellowstone thermal features is still on the horizon Roberto says. When viruses leave their hosts they sometimes carry bits of host DNA with them. Article ! adapted by Medical News Today from original press release. For more information http www.
