Ancient Manuscripts Hold Secrets of a Deadly Livestock Virus

Topic: Biology

Scientists have found DNA evidence of a deadly virus in medieval manuscripts. The sheeppox virus has been affecting sheep herds for over 3,500 years. Researchers extracted DNA from parchment made from animal skins to study the virus's history.

A team of international scientists has discovered that some of Europe's most famous historic manuscripts hold secrets about a deadly livestock virus. The sheeppox virus (SPPV) has been affecting sheep herds for over 3,500 years.

The researchers extracted DNA from the parchment used to make these documents. Parchment is made from animal skins, and it preserves the health of the animals at the time of their death centuries ago. This unique bioarchive allowed scientists to study the history of the sheeppox virus.

The team analyzed over 3,500 years of sheeppox virus evolution and identified traces of the disease in medieval manuscripts. They found that infected animals were used to make some of these documents. The researchers also detected the virus on parchment made from calfskin and goatskin, which suggests rare examples of cross-species infections or contamination during the parchment-making process.

The study's lead author, Louis L'Hôte, said, 'The recovery of ancient DNA of pathogens has completely changed our understanding of infectious disease in the past.' The researchers' findings have significant implications for our understanding of how diseases spread and affect societies throughout history.

Why It Matters

This discovery is important because it shows that ancient manuscripts can hold secrets about the health of animals and people in the past. It also highlights the importance of studying the history of diseases to better understand how they spread and affect modern societies.
