Researchers believe that they discovered the origin of the disease that destroyed millions of people in the 14th century.
Researchers believe they have traced the origins of the Black Death more than 600 years after it killed billions of people in Europe, Asia and North Africa.
The health catastrophe of the mid-14th century is one of the most significant epidemics in human history.
But despite years of research, scientists have yet to discover where the bubonic plague originated.
Now the analysis suggests that it was in 1330 in Kyrgyzstan, Central Asia.
A research team from the University of Stirling in Scotland and the Max Planck Institute in Germany and the University of Tंगेbingen analyzed ancient DNA samples from the teeth of corpses buried in the cemetery near Issyk Kul Lake in Kyrgyzstan.
He chose this region in view of the significant increase in burials in 1338 and 1339.
The team sequenced the DNA of seven skeletons, said Maria Spiro, a researcher at the University of Tbingen.
They analyzed teeth because, according to Spiro, they contain many blood vessels and give researchers “a great opportunity to find the blood-borne pathogens that cause a person’s death.”
Research team finds plague bacteria, Yersinia pestisIn three of them.
“Our study solves the biggest and most fascinating question in history and determines when and where the most infamous and infamous human killer began,” said Philip Slavin, a historian at the University of Stirling.
Research, however, has some limitations, including small sample sizes.
Michael Nap of the University of Otago in New Zealand, who was not involved in the study, praised the work as “really valuable”, but noted:
“Data from many individuals, times and regions will really help explain what the data presented here really means.”
The researchers’ work was published in the scientific journal Nature with the following headline: “The source of the Black Death in Central Eurasia in the fourteenth century”.
What is Bubonic Plague?
Plague is a potentially deadly infectious disease caused by a bacterium called bacteria Yersinia pestis Some that live on animals प्रा mainly rats आणि and on feathers that carry them in their fur.
Bubonic plague is the most common form of the disease that can affect people. The symptoms are due to the painful swelling in the lymph nodes, the formation of a bubble in the groin or armpit called “bubo”.
From 2010 to 2015, 3,248 cases were reported worldwide, including 584 deaths.
Historically, it has also been called the Black Death, because it causes gangrene in certain parts of the body, such as the fingers and toes.
