End of Antibiotic Medicine?
The advent of antibiotics has become a real revolution, they made a commonplace medical operations, which were previously considered to be a miracle. But soon the medicine as we know it today, may come to an end. The bacteria faster and more successfully adapt to new antibiotics, resulting in the development of new drugs becomes unprofitable. In the near future the world may not have the drugs that can beat them. Most routine operations - appendectomy or treatment of cuts - will not be available.
The evolution of bacteria
Concerns about the end of the era of potent drugs are expressed from their inception. The creator of penicillin, which saved the lives of hundreds of thousands of soldiers during the Second World War, Sir Alexander Fleming almost immediately warned that the effects of its opening will not last forever. Accepting the Nobel Prize for Medicine in 1945, he said that sooner or later the microbes adapt to drugs. Fleming prediction came true very quickly. Resistant Staphylococcus penicillin appeared in 1940, although by the time the drug took only a few patients. Tetracycline appeared in 1950. The bacteria took only nine years to adapt to it. Extra high antibiotic erythromycin that can cure whooping cough and pneumonia, appeared on the market in 1953, and the first resistant to the action of bacteria - in 1968.
The drugs become available, the faster the microbes worked out ways to protect against them. Linezolid was presented in 2000, bacteria learned to resist him already in 2001. Daptomycin began massively used in 2003, in 2004 there were the first signs of resistance by. Antibiotics are losing their properties so quickly that it becomes unprofitable companies to develop them. Creating a drug costs about a billion dollars, and these costs simply do not have time to pay off in the few years before the microbes adapt to them. This has affected the number of new developments. In 2004, pharmaceutical companies have worked just over five new antibiotics. For comparison, the number of new drugs for chronic diseases than 500 titles.
Bacteria dangers of terrorism
Medical officials have already sounding the alarm. In September, the director of the Center for Prevention and Control Disease Thomas Frieden said, if mankind is not careful, then soon the world will not remain active antibiotics. Chief physician of the United Kingdom Dame Sally Davies says that the increased viability of the bacteria is not less serious threat than international terrorism - because of them the most minor infections become deadly.
Back to the Stone Age
In 2009, in New York, 67-year-old successfully underwent surgery lane. After her, he picked up an infection in the hospital. All drugs used by doctors were not able to cope with it, and the man died. Without antibiotics, such stories will become the rule rather than the exception. Surgery will be performed only in cases of emergency, especially if the patients are children or elderly people. planned operations risks become too high.
But all this will not be limited. Wired journalist Marin McKenna analyzed, what miracles would lose medicine without antibiotics. People lose the ability to treat cancer and organ transplants, because these procedures are not possible without suppressing the immune system. Any treatment that requires the introduction of drugs into the human, for example, kidney dialysis will be impossible. On the implants will have to forget. This also applies to cosmetic surgery, liposuction, tattoos, and insert new heart valve. Deliveries will be as dangerous occupation, like a hundred years ago, when in 1000, five pregnant women died.
Radically change the diet of mankind: a large piece of meat in industrialized countries, it is carried out with the use of antibiotics. If they stop working, the farmers have to spend more money. According to the estimates of the Council of US pork producers, pig production costs will increase by $ 4.50. And these costs will be passed on to consumers. However, in some cases, will not even increase costs. In 2012, the US Department of Agriculture found that 65% chicken breast and ground beef 44% are resistant to tetracycline, 11% of pork chops are resistant to the five classes of drugs.
