pestis would have been capable of causing severe illness in the lungs or in the blood, Dr Rasmussen and colleagues found it lacked the gene that would allow it to be transmitted by fleas carried on rodents. pestis lineage was at least twice as old as previous estimates.

pestis found on different teeth samples, Dr Rasmussen and colleagues were able to trace the lineage of this microbe back in time. pestis lineageīy sequencing genomes of Y. 'Plague is maybe the most traumatic event that has ever been recorded in human written times of the past, the earliest physical evidence is from the first pandemic in 540 AD,' said Dr Rasmussen. They decided to look for evidence of this in a collection of Bronze Age teeth, 2,800 to 5,000 years old, from settlers across Europe and Asia.īy chance, the first microbe they looked for - Yersinia pestis - turned up across their sample collection.

While the Bronze Age migrants could have deliberately killed the locals, they could also have wiped them out by bringing an epidemic with them, the researchers thought. 'We see that there is a decline of the Stone Age farmers around the time that these Bronze Age people arrive to northern Europe,' said Dr Rasmussen, from the department of systems biology at the Technical University of Denmark Researcher Associate Professor Simon Rasmussen said the discovery of the ancient plague bacteria was actually a side effect of research into how Bronze Age migrants from the Russian steppes replaced Europe's Stone Age populations.

The research has also shown how and when the pathogen evolved into the deadly strain - known as the bubonic plague - spread by fleas, which killed between 30 and 50 per cent of the European population over several centuries.
