This discovery emphasizes that antibiotic resistance genes have spread to the most remote areas on earth.
"Invasions in the Arctic and other regions have increased the speed and breadth of the spread of antibiotic resistance," David Graham, a senior study author and professor of ecosystem engineering at Newcastle University in the United Kingdom, said in a statement. This discovery confirms that the solution to antibiotic resistance must be viewed from a global rather than a local perspective. The "Arctic" and "KDSP" antibiotic resistance "KDSP" has existed for a longer time than humans. In fact, bacteria naturally produce substances that resist other bacteria or microorganisms. (For example, penicillin comes from a mold or fungus. ) "kdspe" and "kdsps", but human beings have accelerated the evolution of bacteria through excessive use of antibiotics. In turn, the development of antibiotic resistance in these organisms has led to an unprecedented new world of drug-resistant strains. Graham said:
A strain carrying blaNDM- 1 gene was found in India in 2008. This gene makes bacteria resistant to an antibiotic called carbapenem, which doctors usually use as a last resort to treat bacterial infections. Since the discovery of blaNDM- 1 gene, it has been detected in 100 countries.
However, when it appeared in the Arctic, researchers were still surprised that a clinically important [antibiotic resistance gene] from South Asia was obviously not native to the Arctic. Graham said, "By traveling in the Arctic, it is no longer a" primitive "and" parasite ".Researchers actually want to know the types of antibiotic resistance genes that existed before the antibiotic era. But they found that a large number of modern antibiotic resistance genes already existed. In this study, the researchers analyzed the DNA extracted from the soil core of Spitsbergen Island in Norway in the Arctic Ocean. They always * * * find 13 1 antibiotic resistance genes, many of which do not seem to be from local sources.
The researchers say that these genes may be spread through the feces of birds, other wild animals and human tourists in this area.
But researchers can still find what they are looking for: isolated polar regions with low levels of antibiotic resistance genes. "They may provide a natural baseline for antibiotic resistance," Graham said.
Claire McConn, the lead author of the paper and a research assistant at Newcastle University, said in a statement that the correct use of antibiotics in medicine and agriculture is essential to reduce antibiotic resistance. But she added that it is also important to know exactly how antibiotic resistance spreads around the world, including through water and soil.
