A team of scientists from the University of Newcastle (UK) hoped to find it in Arctic Superb traces dating back to the use of antibiotics. However, they were surprised: They found several genes belonging to modern microorganisms, including those originating in India.
On Superbugs are those who were able to develop resistance to antibiotics. Although this is a natural defense mechanism, the abuse of antibiotics accelerates its evolution, creating "resistant species that have never been seen". One of them is the one who brings the blaNDM-1 gene, discovered for the first time in India in 2008, and is characterized by the immune system of end-user antibiotics. From that moment on, it was found in more than 100 countries, although researchers were shocked by their presence in the Arctic.
"It's clear that this gene is not local to the Arctic, if we think it originates from South Asia," says David Graham, chief author of the article published in the scientific journal International environment, in a statement. "Invasion in areas like this strengthens the speed and capacity of expanding superbacteria", he thinks. In this regard, he stressed the need to address antibiotic resistance from a global, not from a local perspective.
Experts understand this the spread of these microorganisms may be due to the fecal matter of birds and other wildlife, as well as human visits to the area. Despite this finding, they could also find isolated areas that "can show us the basis of microbial resistance".
