antibiotics should be limited to an average of less than nine daily doses per person per year in an attempt to prevent the emergence of untreatable superbugs, health experts have warned global.
Writing in the journal Science, which called on world leaders gather for a special meeting of the United Nations on the issue next month to take action decision to reduce antimicrobial resistance.
This threatens to send medicine to the days before the discovery of the first antibiotic, penicillin, when people could die from a simple scratch in the garden.
A superbug resistant to the antibiotic of “last resort”, colistin, was found in the UK in December of human cases and three farms.
Under David Cameron, the UK led calls for global action to address the problem. Cameron warned of “catastrophic consequences” potentially not done, announcing plans to try to halve the number of drug resistant infections in Britain in 2020.
It has been estimated that 10 million people they could die every year worldwide by 2050 as a result of antibiotic resistant bacteria.
The document, experts from the UK, US and China wrote. “We propose that no country consumes more than the overall level of the current median – 8.54 defined daily doses per inhabitant per year estimate that this reduce the total use of 17.5 percent globally “.
This is an average for each member of the population, so that people in dire need of antibiotics that can save lives, such as those patients immune system or compromised surgery would still be able having substantially more than this figure.
The experts add: “Further reductions could be achieved through public campaigns aimed at doctors and patients, to discourage inappropriate use of antibiotics, particularly in response to seasonal flu.”
flu is a virus, so antibiotics have no effect, but many people do not require drugs their physicians independently. Also they do not work against most colds, most cough or sore throat.
Our immune system can also handle minor without any external help bacterial infections.
The paper said there was “considerable potential” to reduce the use of antibiotics in agriculture.
The drugs are administered to livestock, not because they are sick, but to grow faster.
Giving regular and low of antibiotics thus described as “perfect” way to produce resistant bacteria because it creates an evolutionary pressure to develop resistance without actually kill the bacteria dose.
“propose comprehensive global phasing out of the use of antibiotic growth promoters”, the newspaper said.
“establishes a period of five years would be appropriate, given the urgency of the problem.
” This could avoid much of the projected 67 percent increase in the use of animals farm between 2010 and 2030. “
experts also said that the imposition of restrictions on effluent antibiotics – manufacturing of pharmaceuticals, agricultural operations and hospital waste – should be an” urgent priority “
They can get into rivers and contribute to the accumulation of resistance genes in the water and soil.
antibiotics are essentially the product of chemical warfare carried out by fungi, molds and .. some forms of bacteria
Thus bacteria that make the sick human being can be countered with a semi-synthetic drug from another bacterium that kills
bacteria reproduce – and at both evolve – quickly and the large number of people. So a drug that kills 99 percent of them soon lead to a new population of bacteria that descend from the one percent who were able to survive.
Dr. David Brown, chairman of the science of charity to antibiotics Research UK, said the spread of antibiotic resistance is a global threat.
“What we have to consider is that there are great differences in the needs of patients,” he said.
“People with cystic fibrosis, people with immunosuppression or people who have had invasive difficult surgery will need more [than the proposed average limit].
” It is important that these people receive the antibiotics they need but equally it is important to reduce the unnecessary use of less severe conditions. “
the Department of Health said the government is” leading the fight against infections resistant to medicines “in collaboration with the UN and groups G7 and G20 countries.
“resistant infections drugs have a devastating potential and we have been clear that the world needs to act now to save millions of lives,” he said in a statement.
“, which it has already been committed to halving the inappropriate prescribing of antibiotics in humans in 2020. we have already made good progress.
“The NHS has already taken action with more than 2.6 million fewer prescriptions in 2015-16. This is a reduction of more than seven percent compared to 2014”.
The Government has also launched a £ 268m ‘Fleming Fund’, the name of Sir Alexander Fleming discovered penicillin, to help other countries improve monitoring of antibiotic use.
