News24xx.com -  Black Death is a plague epidemic that killed hundreds of millions of people in Europe in the 14th century. 

And now, through a 3,800-year-old skeleton, the scientists discovered the cause of Black Death. The 3,800-year-old skeleton was found in the Samara region of Russia.

Black Death or pes has caused by Yersinia pestis bacteria. These bacteria can cause illness if a human was infected by rat urine that was exposed to water.


A DNA examination of a 3,800-year-old skeleton suggests that disease could have existed in the world long before the disease of Black Death attacked. 

On the other hand, the bacterium Y. pestis is said live in lice, which transmit these bacteria to mice, that cause death in humans.


"The DNA of Y. pestis has been discovered about 4,000 years ago, and has the genetic characteristics that needed for the transmission of diseases from ticks to mice, humans and other mammals," said Dr. Maria Spyrou, as quoted by The Independent on Saturday, June 16 2018.


In a study published in the journal Nature Communications, the bacteria Y. pestis has been called since the Bronze Age. 

But because of the underdeveloped of human civilization, and the weak of transportation, so the new disease becomes a health threat when it was entering the next millennia.


Based on these findings, it is believed that Black Death pandemic not only attacking in western and southern Europe, but also penetrated to northern Europe and some area of Asia.
