Scientists have reconstructed the genetic code of the medieval plague
Now experts have received at the hands of the genetic code of the bacteria Yersinia pestis, provoked the plague. For this, they have identified DNA fragments of ancient organism causing the epidemic of the Black Death, from the teeth of medieval remains found in London. You will need the material, taken away from the pulp of the tooth, said BBC.
According to experts, the pathogen is the ancestor of all modern forms of plague. They also believe that the medieval plague outbreak is the first real epidemic of plague in history. Indeed, mankind seldom faced with such a serious threat. Between the years 1347 and 1351 has led to bacteria plague. The infection was transferred flies quickly spread across Europe and eventually taking the lives of nearly 50 million people.
Said Professor Johann Kraus of the University of Tabingena, who took part in the study of DNA of plague: "All modern strains of plague associated with the medieval plague. Earlier it was assumed that the Black Death was the successor of the ancient infection. For example, in the sixth century Justinian plague broke out – the epidemic that killed about 100 million people. Now, however, scientists have found that the ancient and medieval epidemics are not related and are caused by different pathogens. "
