While the latter is usually more virulent than bubonic plague, the team say the genetics of the early strain suggest its ability to spread may have been compromised. The team screened the genetic material for signs of known pathogens, including Y. pestis the bacterium that causes the plague, revealing one of the men, aged 20 to 30 years old, not only had DNA fragments, but also proteins, indicating he had died with a now-extinct form of the plague in his bloodstream.
