Not Good! Super Bug Genes in the Arctic


There Are “Superbug” Genes In the Arctic.  They Should Not Be There.

A “superbug” gene that was first detected in India — and allows bacteria to evade “last resort” antibiotics — has now been found thousands of miles away, in a remote region of the Arctic, according to a new study.

The findings underscore just how far and wide antibiotic resistance genes have spread, now reaching some of the most far-flung areas of the planet.

“Encroachment into areas like the Arctic reinforces how rapid and far-reaching the spread of antibiotic resistance has become,” senior study author David Graham, a professor of ecosystems engineering at Newcastle University in the United Kingdom, said in a statement. The findings confirm that solutions to antibiotic resistance “must be viewed in global rather than just local terms.” [6 Superbugs to Watch Out For]

Antibiotic resistance has existed for much longer than humans have been around. Indeed, bacteria naturally produce substances to defend themselves against other bacteria or microorganisms. (For example, penicillin comes from a type of mold, or fungus.)

But through overuse of antibiotic drugs, humans have accelerated the rate of bacterial evolution, and in turn, the development of antibiotic resistance in these organisms, leading to “a new world of resistant strains that never existed before,” Graham said.

One such strain, carrying a gene called blaNDM-1, was discovered in India in 2008. This gene gave bacteria resistant to a class of antibiotics known as Carbapenems, which doctors generally use as a last resort to treat bacterial infections. Since its discovery, the blaNDM-1 gene has been detected in more than 100 countries.

But the researchers were still surprised when it showed up in the Arctic. “A clinically important [antibiotic resistance gene] originating from South Asia is clearly not ‘local’ to the Arctic,” Graham said.

By traveling to the Arctic, the researchers were actually hoping to get a picture of the types of antibiotic resistance genes that existed before the era of antibiotics. But they found that a slew of modern antibiotic resistance genes were already there.

In the study, the researchers analyzed DNA extracted from soil cores in Spitsbergen, a Norwegian island in the Arctic Ocean. They found a total of 131 antibiotic resistance genes, many of which did not appear to be of local origin.

These genes likely spread through the fecal matter of birds, other wildlife, and human visitors to the area, the researchers said.

But the researchers were still able to find what they were looking for: isolated polar areas where levels of antibiotic resistance genes were so low “they might provide nature’s baseline of antimicrobial resistance,” Graham said.

Appropriate use of antibiotics in medicine and agriculture is crucial to reducing antibiotic resistance, Clare McCann, lead author of the paper and a research associate at Newcastle University, said in the statement. But she added that it’s also critical to understand exactly how antibiotic resistance spreads around the world, including through routes such as water and soil.

The study was published Jan. 27 in the journal Environment International.

  1. Dear Mrs. Duff – I can’t tell you how many tons of frozen overburden { permafrost } I helped de frost with a water cannon { Intele-giant} , in order to get to the gold bearing gravel , which is 2- 3 feet abv the bedrock in Ophir , Alaska. And from the sub-Arctic to the Arctic , I never heard of anyone getting ill from it. In fact, everyone knows once your push the overburden into the river or creek – the fish love it. Maybe the Permafrost in Norway has more dead people dissolved in it – LOL My bet is that Big Pharma is playing in the Arctic and as usual is using their Big Media to push it. My 2 cents- Thanks

  2. They are also using a lot of biological additives in the nutritients they give the farmed salmon.
    Might not that give genetic material yet another path to the Northern Ice Sea?
    “Fish farmers sometimes give the salmon antibiotics and animal drugs to keep them in good health. Some people have concerns that the use of antibiotics could increase human antibiotic resistance.”
