New research shows that leprosy existed in the Americas before Europeans arrived
Scientists say a species of bacteria rewrites the history of when an infectious and potentially deadly disease first arrived in the Americas. This has appeared very early on the arrival of European explorers.
With the help of American universities, researchers from the Paris Institute in France recently announced in a press release that a second bacteria also causes disease in the Americas, namely leprosy or Hansen's disease.
In the past few years, many people have believed that the bacteria has been called Mycobacterium leprosy Caused leprosy and was spread only in the United States by early European explorers and settlers.
However, the revelation of the second bacteria suggests the theory of blamed settlers on their minds, as existing pressures are already known in the continent as homes in the New World.

bacteria Mycobacterial haemophilia Researchers say that it had existed and infected humans for 1,000 years before the arrival of Europeans.
The study's first author, Dr. Maria Lopopolo, Ph.D., said in the Institute Pasteur researchers that it changed everything about leprosy in the Americas.
“This discovery changes our understanding of the American history of leprosy. It shows that a form of the disease was already prevalent among the indigenous population before Europeans arrived,” she said in a press release.

The study was led by scientists from the National Center for Science and Technology of France and the Microbial Paleontology Laboratory at the University of Colorado, USA. Mycobacterial haemophilia It was found in a Mexican patient in 2008, and a red squirrel in the British Isles was found in 2016.
Reconstruct the genome using advanced genetic techniques Mycobacterial haemophilia Ancient individuals from Argentina and Canada, scientists have found that two strains from different regions are genetically close Mycobacterium genomic genealogy, which means bacteria spread rapidly throughout the continent.
This version indicates that the results confirm Mycobacterial haemophilia Already spread across North and South America.
Researchers were able to study more than 800 different DNA samples from ancient human remains, and recent medical cases showed signs of leprosy. (iStock)
According to the press release, researchers worked with indigenous communities, various international agencies and archaeologists to study more than 800 samples of DNA from ancient human remains, with recent medical cases showing signs of leprosy.
The study proves that human history can change, says Nicolás Rascovan, the lead author of the study of the institute.
“We're just beginning to reveal the diversity and global movement of this recently identified pathogen,” he said. “This study allows us to assume that there may be unknown animal storage.”

The Centers for Disease Control and Prevention (CDC) says leprosy can affect patients' nerves, skin, and eyes and receive antibiotic treatment. The Centers for Disease Control and Prevention (CDC) said that in the United States, there are as many as 225 people and 250,000 people worldwide, Conson's disease.
