Y Pestis



A study by an international team of researchers published in October 2010 confirmed Y. pestis was the cause of the Black Death and later epidemics on the entire European continent over a period of 400 years. The team used ancient DNA and proteins recovered from the bodies of plague victims buried in Hereford in England, in Saint-Laurent-de-la-Cabrerisse in France, and Bergen op Zoom in the Netherlands to identify the pathogen. They found two previously unknown, older strains of Y. pestis that had spread from China by two different routes, rather than the modern Y. p., orientalis and Y. p. medievalis.
