A team of Swedish geneticists discovered in a 5,000-year-old corpse a strain of bacteria that caused the plague for the first time in Europe.
The bacterium was extracted from the DNA of the body teeth found in southern Sweden, belonging to a 20-year-old girl. The microorganism discovered was Yersinia Pestis, responsible for the plague pandemic on the European continent in the stone age, according to researchers
According to the portal Live Science, the remains found Thursday (6) have the same genetic variations that cause deadly diseases in our time.
In the same grave, another corpse was found, whose remains also possessed the bacterium.
After genetic badysis, after studying the genome of more than a thousand corpses, it was determined that the type of bacterium plague that had killed the Swede had appeared.

Ancient and unknown plague strain found in a 5,000-year-old grave Sweden
The results of the study revealed that the virus had spread throughout Europe from southeastern Russia to Sweden in a very short period of time. about 600 years old.
The author of the Argentine biologist and researcher at the University of Aix-Marseille, Nicolas Rascován, said that at the time of the pandemic, he was born in Paris. There were no great human migrations. it could just "Exactly when we saw the plague spread, there were great technological innovations, such as wheel transport and animal traction, which was ideal for spreading the disease over long distances," says Rascován.
At the time when the young woman was found, that is to say, 5,000 years ago, the first cities where men and animals lived together in precarious hygiene conditions. At that time, there was a marked population decline (between 30% and 60%), similar to what had happened in the Middle Ages with the Black Death.
That is why several cities were burned and abandoned, marking the end of the
