Scientists say that the type of bacteria rewrites history when infectious and potentially fatal illness first arrived in America. And it took place long before the arrival of European researchers.
Researchers from the Pasteur Institute in Paris, France, with the help of the US University, recently announced disease known as leprosy, or Hansen's disease, in America.
In past yearsMany believed that a bacterium known as Mycobacterium Leprae He caused a leprosy and that it spread only in America only by early European researchers and settlers.
Nevertheless, the revelation of the second bacterium makes this theory of the accusation of settlers in his head, since the existing strain was already on the continents calling the new world a house.

Bacterium Mycobacteria lepromatosis Researchers say that they existed and infected people for 1000 years before the arrival of Europeans.
Dr. Maria Lopopopo, the first author of the study and researcher of the Laboratory of microbial paleogenomics at the Pasteur Institute, said that he was changing everything about the leprosy in America.
“This discovery transforms our understanding of the history of leprosy in America. This shows that the form of the disease was already endemic among the population of indigenous peoples long before the arrival of Europeans, ”she said in the press release.

Research – led by scientists from the Laboratory of microbial paleogenomy at the Pasteur Institute, along with the French National Center for Scientific Research and the University of Colorado in the United States – began after Mycobacteria lepromatosis It was discovered by a Mexican patient in 2008, and red proteins in the British Isles in 2016.
Using advanced genetic methods to restore genomes Mycobacteria lepromatosis From ancient people from Argentina and Canada, scientists found that two strains from different regions were genetically close to Mycobacterium The family tree of the genome, which means that bacteria quickly spread throughout the continent.
The release said that the results confirmed that Mycobacteria lepromatosis Already spread throughout North and South America.
Researchers were able to study more than 800 different DNA samples from ancient human remains, and recent medical cases showing signs of leprosy. (Istock)
Researchers worked in cooperation with the communities of indigenous peoples, various international institutions and archaeologists, according to publication, and were able to study more than 800 DNA samples From ancient human remains and recent medical cases showing signs of leprosy.
Nicholas is relaxed, the leading author of the study in Pasteur InstituteHe said that the study proves that the history of mankind can be changed.
“We are just starting to reveal the diversity and global movements of this recently identified pathogen,” he said. “This study allows us to assume that there may be unknown animal tanks.”

A Centers for control and prevention of diseases (CDC) says that the leprosy can affect the nerves, skin and eyes of patients and is treated with antibiotics. According to CDC, up to 225 people in the USA and 250,000 around the world, contracts with Hansen's disease.
