In the Arctic they found genes of superbakteria from India



A team of scientists from the University of Newcastle (United Kingdom) hoped to find in Arctic Traces of superbugs that date before using antibiotics. They were, however, surprised: They discovered several genes belonging to modern microorganisms, one of which came from India.

The Superbugs are those that have developed resistance to antibioticsAlthough it is a natural defensive mechanism, the abuse of antibiotics has accelerated its development, creating "resistant strains that have never been seen". One of these is the blaNDM-1 gene, first discovered in India in 2008 and characterized by its immunity to last-resort antibiotics. Since then, it has appeared in over 100 countries, although researchers have been shocked by their presence in the Arctic.

"It is obvious that this gene is not local in the Arctic if we think it comes from South Asia," said David Graham, the lead author of an article published in a scientific journal International environment, in a statement. "Invasion in such areas strengthens the speed and ability of expanding superbakteria", he thought. In this regard, he stressed the need to address antibiotic resistance from a global rather than a local perspective.

Experts understand the spread of these micro-organisms can be caused by the fecal matter of birds and other wild animals, as well as visits by people in the area. Despite these findings, they were also able to find isolated areas that "can show us the basis of microbial resistance."
