Named cause of the most murderous in human history of a pandemic

Названа причина самой убийственной в истории человечества пандемии

The bacterium Yersinia pestis was the cause of deadly pandemics.

An international team of scientists analyzed two genome-the oldest known causative agents of bubonic plague, the age of which reaches almost 4,000 years.

According to the researchers, they found a strain of Yersinia pestis, which is the “ancestor” of the infection that caused such a pandemic as: “the Black death”, “Justiniana plague” and the third plague pandemic in China.

They note that the bacterium Yersinia pestis was the cause of deadly pandemics in the era of the Ancient world, middle Ages and New time.

New strains of Yersinia pestis was isolated from two of the victims of the disease buried in one grave 3800 years ago. This finding, according to geneticists, allows you to postpone the time of appearance of dangerous forms of Yersinia pestis can infect rodents, humans and other mammals, for 1000 years.

Microorganisms possessed all the necessary genes for the development of the bubonic form of the disease.

Additionally, in January 2018, researchers from the universities in Oslo and Ferrari declared that a pandemic of the bubonic plague in medieval Europe, which was called “Black death” was caused not by rats but by people. And fleas and lice which are parasitic on man, has contributed to the spread of the deadly disease.
