DNA Confirms Cause of 1665 London's Great Plague (bbc.com) 77

Slashdot reader JThaddeus writes: The BBC reports that a 17th-century mass grave uncovered in London confirms the identity of the bacteria responsible for the Great Plague of 1665-1666. "Testing in Germany confirmed the presence of DNA from the Yersinia pestis bacterium -- the agent that causes bubonic plague -- rather than another pathogen." The grave contains approximately 3,500 skeletons... Teeth were removed from some of the skulls, and their pulp tested at the Max Planck Institute in Germany. Positive results were found in 5 of 20 individuals tested.
"To reassure anyone worried whether plague bacterium was released from the excavation work or scientific analysis, it doesn't survive in the ground," reports the BBC. The 3,500 graves represent roughly 3.5% of London's 100,000 victims of the Great Plague -- one-quarter of the city's entire population.

    The summary suggests that some "what terror have you unleashed?!" doomsday scenario could unfold with Yersinia Pestis being resurrected from extinction... but that's impossible. Yersinia Pestis still exists and causes about a dozen cases of bubonic plague annually, nowadays. It's easily treated with antibiotics, and those of European descent are thought to be resistant to it. If I recall my Wikipedia correctly.

      In addition to the antibiotics the bacteria culled the part of the population that weren't resistant enough to cope with it. This is why the earliest occurrences of the Black Death usually were worst while the subsequent were milder. Darwin at work.

        They're still European for another two years (and it's a rolling two years as it keeps not starting) only after that will they not be Europeans and any children they have at that point may not be immune to the plague unless they cover it in their negotiations - that's why it takes so long, there are a lot of issues like this to consider.

      Easily treated is bit of an understatement. A properly treated bubonic plague causes a risk of death of 10% according to wikipedia, and there is still the problem that symptoms appear in a few days after contagion, and death in 7-10 days from contagion, so it is critical an early diagnosis. Septicemic and pneumonic plague are even worse.

      I thought that Yersinia Pestis has been known to be the organism responsible for the plague for a long time, this confirms it. From memory the theory was that the black plague was caused by a strain that was much more virulent than the one normally found now.

      The article states that they have found bacterial DNA in 5 samples and are still looking for more to reassemble the genome of the plague bacterium so they can compare it to the current genome.

        It's been shown that most of the plague variants alive today are descendants of the 1347 plague (the Black Death). The same goes for all the genomes we have from intermediate epidemics between 1348 and now, which will probably include the 1665 plague once the genomes are known. The big discovery is that there are almost no genetic differences between any of these strains. The strain that killed all those people in 1347 was basically the same strain you can find in prairie dogs in the American Southwest tod

    The thing to reassure people of is the fact the bubonic plague is treatable now unlike back then not that it can't live in the ground as that is a fairly pointless reassurance as the bacteria is still very much alive and well in the world. It still occasionally raises its head with outbreaks and results in 100+ deaths a year.

      The historic practice was that when the graveyard got full the oldest plots would be dug up and the bones would be placed in the ossuary (typically a small stone "tomb" you still see in some old graveyards) When the ossuary was full the bones would be removed and burnt on a "Bone Pyre" w

Stop paying, and if the ground has had enough time to decompose a body - which varies with latitude, altitude (temperature) and soil properties - the

      Just for starters : they were looking at microbe fragments preserved in teeth - because these are some of the most decay-resistant bits of the entire body. But for 1665 I wouldn't be astonished if most people who went into the ground for any reason had either badly-eroded teeth (grit in bread) or badly-rotted teeth (caries), or just plain no teeth.
