Arctic superbugs traces

Newcastle University Scientists (United Kingdom) have detected 131 antibiotic-resistant genes, some microorganisms make superbacteria very hard against the treatments in the artic region.

The discovery was carried out on the island of Spitsbergen (Svalbard, Norway) on the land of the archipelago, which until now has been considered against this kind of pollution.

"They are polar regions Predominantly in the Earth's ecosystems, to establish a reference section prior to antibiotics to understand the rate of spread of resistance gene pools ". said in a statement David Graham, research director.

But the results of the research published in the journal International Environment, Only Kongsfjord cave points are displayed on the island of Spitsbergen.

Scientists have discovered genes with antibiotic resistance found in India, nearly 13,000 kilometers away. These are the BlaNDM-1, a gene that was detected in hospital environments in 2008, in urban and shallow waters in 2010, offering antibiotic resistance or antibiotics. Since then, blaNDM-1 has been detected in more than 100 countries, sometimes as new variants.


All genes worried about it Its presence indicates that it has microbes or DNA fragments against anti-microorganism resistance treatments.

Gene BlaNDM-1 stands out Provides endurance resistanceUltimately, all others fail a type of antibiotic. There are currently antibiotics to deal with bacterial endothelial resistance.

Indeed, Graham has discovered 131 genes with nine antibiotics that are used to treat infections.

For example, a gene that provides resistance to bacteria has been detected in all soil samples, and 60% of the gene control in blaNDM-1 was discovered.

Transmission through birds

According to Graham, these genes have mostly come to the Arctic soils by the arrival of poultry birds and other animalsMen rarely visit.

"After being less than three years old, the Indian water forces to detect the presence of blaNDM-1, we find ourselves miles away, in an area where human influences have diminished." explained the researcher.

"Arctic-like invasion of the area strengthens the idea Antibiotic resistance has been effective and rapid, which confirms that this problem has to be global and not a place for solutions, it has influenced.

In fact, according to the World Health Organization (WHO), the resistance to antibiotics is a global crisis, and One of the biggest threats to global health, food security and development.

Humanity has accelerated research

"Humans have done excessive antibiotics around the world accelerate the rate of evolution -Battery- so far it was not the resistance to create a new universe of tension " explain Graham

As a result, while natural bacteria are easy to adapt and resist, there are few antibiotics in development, "It's simply not profitable to do them" According to Graham.

In order to prevent serious anti-biotic resistance, scientists not only propose improvements in medicine and agricultural management. Analyze the transmission of this phenomenon better water and soil.
