Did the Black Death give birth to modern plagues?
A paper published in Nature today reports a genome sequence taken from bacterial remains of the teeth of victims buried in London’s East Smithfield cemetery. The area was used in the 14th century to cope with the large number of dead bodies amassed during the first outbreak of the great plague, or Black Death.
It has long been thought – and now shown – that the plague was caused by the bacteria Yersinia pestis.
The work, by Kirsten Bos of McMaster University and an international group of scientists, has the potential to help us better understand contemporary outbreaks of plague across the world.
Historically, the bubonic plague came in three waves.
The first was in the Mediterranean regions in 541 A.D. and is known as the Plague of Justinian. The wave of medieval plague, better known as the Black Death, hit Europe between 1348 and 1350, and is said to have claimed an estimated 30–50% of the European population.
After about 100 years this plague died out, but reappeared in China in the 1800s – this third wave is still responsible for 2,000 cases annually worldwide.Comment on this article
