A group of French, Swedish and Danish scientists found that the deadly bacteria that caused the plague epidemic in the fourteenth century, throughout Europe, could dwell in Scandinavia long before the terrible pandemic.
Recent archaeological excavations have revealed the presence of Yersinia pestis, Yersinia pestis, in the remains of twenty women who died 4900 years ago in Sweden, reports the Daily Mail.
Researchers believe that the peasants who lived 4,500 years ago, may have also caught the “Black death” after it spread to the provinces.
According to the researchers, their discovery could rewrite history, because for the first time demonstrates what a dangerous infection was not brought from Asia, and has developed on the territory of Europe itself.
Evolution of plague were established on the basis of genetic data obtained from tissue samples of the body of ancient people and determine the sequence of development of modern strains of the plague.
The genes that are turned pneumonic plague deadly disease, found in the remains of the Swedes. Comparing them with other strains, the researchers were able to determine that the ancient plague Bacillus is closest to Y. pestis. This suggests that during the late Neolithic period there were numerous strains of the plague.
Author Simon Rasmussen (Rasmussen Simon) believes that the results of scientific rabot propose a new theory about how the plague was spreading.
The mass migration of people from the Eurasian steppe into Europe, as we know, occurred about 5,000 years ago. But as these cultures were able to displace the Neolithic culture of agriculture that existed in Europe at the time, is a hot button topic.
Early studies suggested that the invaders brought with them a plague, destroying a large settlement of farmers of the stone age.
The strain of plague found in Swedish women differed from Y. pestis and probably developed before the migration, when European settlements in the Neolithic age have begun to crumble.
In Europe began appearing city with a population of 20,000 people, making it possible for professional specialization, new technologies and trade. Do not be deceived, the level of sanitation was low.
The plague may have migrated along the trade routes made possible by wheeled traffic, and quickly spread throughout Europe.
Then the plague has spread from big cities to small communities, one of which lived found the girl.
Recall that global warming can lead to repeated epidemics of bubonic plague, which killed tens of millions of people in the Middle ages.
As reported by the portal “Znayu” protein that binds insulin-like growth factor fruit flies, will reduce the number of malicious mosquitoes, which carry malaria and yellow fever.
Also “Znayu” wrote that scientists have created a single new vaccine against anthrax and pneumonic plague.
