What Happens If the Overuse of Antibiotics Leads to Them No Longer Working?
Posted on August 9, 2011 Comments (3)
Antibiotics have been a miraculous tool to keep up healthy. Like vaccines this full value of this tool is wasted if it is used improperly. Vaccines value is wasted when they are not used enough. Antibiotics lose potency when they are overused. The overuse of anti-biotics on humans is bad (especially the huge amount of just lazy, not scientific use). But the massive overuse in livestock is much worse, it seems to me.
The health system in the USA is broken in a huge way in which it is broken is the failure to address creating systemic behavior that promotes human health and instead just treating illness. It is much better to avoid a situation where we breed super bugs and then try to treat those super bugs that have evolved to be immune to the antibiotics we have to use.
When antibiotics no longer work
Drugs are given to livestock for multiple reasons. An obvious one is for the treatment of diseases. When livestock are sick, veterinarians administer a significant dosage in hopes of eliminating the animal’s affliction. Another reason is preventative. Animals in close quarters are more susceptible to infection, so farmers will often administer medicine to healthy animals in order to nip anything nasty in the bud. Most controversially, though, members of the agricultural industry use antibiotics for the express purpose of promoting livestock growth.
It’s a well-known, if not entirely intuitive, fact that healthy animals who are fed small, or “sub-therapeutic,” doses of antibiotics will wind up larger than their unmedicated counterparts. In many such cases, these drugs are given to livestock through their feed or water, and without the prescription or oversight of a veterinarian, according to Dr. Gail Hansen, a senior officer at the Pew Campaign on Human Health and Industrial Farming.
An estimated 80 percent of all antibiotics in the U.S. are given to food-producing livestock, according to the FDA. And approximately 83 percent of that medicine is “administered flock- or herd-wide at low levels for non-therapeutic purposes, such as growth promotion and routine disease prevention,” according to a lawsuit filed against the FDA in May. These figures could have very real consequences for public health, because the Catch-22 of this antibiotic abandon is the widespread development of drug-resistant bacteria, colloquially referred to as “super-bugs.”
…
In 2006, the European Union banned all use of antibiotics on livestock for growth promotion. And the U.S. Senate will consider similar legislation this year. Sen. Dianne Feinstein, D-Calif., reintroduced the “Preservation of Antibiotics for Medical Treatment Act” last month, which would significantly rein in agricultural drug use, and strictly prohibit the application of sub-therapeutic doses of drugs that have benefits for humans.
Still, the agricultural industry disputes data about its use of antibiotics and the rise of super-bugs, and it has aggressively fought efforts to legislate the matter. As a result, it’s hard to tell how far the legislation might proceed.

The end of the era of antibiotics
…
Antibiotics require a prescription in America, but our nation is still very much a part of the problem. Patients routinely demand these drugs, and doctors acquiesce, for respiratory infections and other ailments that will not respond to antibiotics because they are caused by a virus. We use soap with antimicrobial agents when regular soap does equally well. And we allow farmers to feed antibiotics to livestock in horrifying amounts, not to treat illnesses but to make farming more efficient.
Antibiotic Resistance in Livestock: More at Risk Than Steak
…
The single greatest factor driving resist- ance to a given antibiotic is simply use of the drug. The more an antibiotic is used, the more the bacteria become resistant to it. For this reason, experts say, antibiotics should be used sparingly, and at dose levels intended to kill all or as many of the bacte- ria causing an infection as possible. If too little antibiotic is used (undertreatment), the most susceptible bacteria are killed off, leaving a hardy group of survivors that grow and multiply into resistant strains.
Human abuse of antibiotics in particu- lar is a major public health problem. Many patients demand anti- biotics routinely, and just as many doctors dispense antibiotics indiscrimi- nately—often for viral infections against which the drugs are useless. And it’s not uncommon for patients to stop taking antibiotics as soon as they feel better, killing only a fraction of the bacteria that are making them sick. Antibiotic use around the world is character- ized by widespread chronic under- treatment.
Chronic undertreatment in agriculture, particularly for non- therapeutic uses no matter how they are defined, is also endemic.
Throwing away the miracle of antibiotics because we are too lazy, too shortsighted, too greedy or too uncaring is going to bring misery to millions of people. That is why I have written about this problem for years. We have had warning. We have largely ignored those warnings. If we bring about a massive decline in the usefulness of antibiotics it will be due to our decision to not take care and at wisely. That is going to be a very high cost. I hope we will avoid it, but I fear we will not. The best I realistically hope for is we can reduce the suffering we cause those that follow us due to our refusal to seriously address the problem we are creating with our actions and inaction.

We could also take another look at phage therapy, where you inject a bacteria with a virus that kills the bacteria, but doesn’t kill you. Felix d’Herelle first used it between 1915 and 1917.

Our continued poor antibiotics practices increase the risk of many deaths. We are very poor at reacting to bad practices that will kill many people in the future…
