‘Virus Hepatitis B’ Scientific discovery of a modern enemy in ancient skeleton:
Scientists have retrieved DNA from the oldest viruses to be infected for human beings.
Scientists have said that they have retrieved DNA from the oldest virus infected with humans – and some of them have been successful in the revival of the laboratory.
Viruses were all strains of hepatitis B. Two researchers teams independently discovered their DNA in 15 ancient skeletons, which was the oldest farmer in Germany 7,000 years ago.
A group of scientists from the University of Copenhagen and Cambridge University have analyzed DNA of humans, which lived approximately 4.5 million years ago and found the oldest virus, hepatitis B, which he successfully revived in the laboratory.
Previously, the researchers searched a mammified body of a small child from Naples, Italy. After the initial study, scientists said that the 450-year-old child was buried in Basilica of St. Domenig Maggiger and it was from the 16th century boy. After analyzing DNA and bone samples, researchers found out that the boy has died from hepatitis B and scientists have claimed that now they can say how old the virus is.
However, new research results are considered the oldest evidence of the existence of hepatitis B. Thousands of years ago, this virus was shown by affected people compared to this belief. The findings were published in Nature Magazine, where researchers said that they analyzed the genome of 304 people, who lived on Earth seven to two thousand years ago.
SBS reported that Edward C. Holmes, a virologist at the University of Sydney, “It’s a hugely important moment in our understanding of one the most important pathogens of humans.”
A Janetists at the University of Copenhagen, Esk Wiltslev led the two groups in this research process. In the first study, researchers analyzed genomes of 137 people living in Eurasia. In the second study, he used the first analysis of DNA sample of 167 people and indexed them in another study. Eventually, he was diagnosed with Hepatitis B virus in the remains of 25 people, and lived 4.5 million years ago out of those skeletons.
Hendrik Poiner, a DNA expert at McMaster University, said, “It gives a whole new light on understanding human suffering in the past.”
According to Science Daily, another international team led by researchers at the Max Planck Institute for the Science of Human History and Kiel University has reconstituted genomes from the ancient strains of hepatitis B virus. In this case, scientists also said that the virus DNA has indicated that hepatitis B was spreading in Europe at least 7000 years ago.
However, hepatitis B is a viral disease, which causes severe liver infection. It can be transmitted directly through blood contact or when these fluids come in contact with broken skin or mucous membrane of an insecure person.
Max Planck Institute for the Science of Human History and Kill University has collected an international team of scientists to study the Stone Age and medieval European specimen. Scientists discovered the strains of hepatitis B virus in ancient DNA. It means one thing: 7,000 years ago Hepatitis B was present in Europe.
