Global warming is bringing back ancient viruses from the dead as frozen ‘zombie viruses’ are making their way back into the earth as the ice melts in the Northern Hemisphere.
To get to know these viruses better, a team of scientists from the French National Centre for Scientific Research, have reanimated several of them.
13 frozen viruses were found in seven different samples from the Siberian permafrost and one of them was nearly 50,000 years old.
‘This study confirms the capacity of large DNA viruses infecting Acanthamoeba to remain infectious after more than 48,500 years spent in deep permafrost,’ said the preliminary study led by microbiologist Jean-Marie Alempic.
Most of the viruses found in the study were proposed to be part of the Pandoraviridae family of viruses that have double-stranded DNA and infect amoebae.
