Today’s people are so used to the idea that any antibiotics can cure just about any infections. And truly, the development of antibiotics is well thought out among the most important rise of modern science and antibiotics has saved millions of lives. However, antibiotic is becoming a rising threat to the human health and is happening worldwide. What is antibiotics? — a chemical produced by fungi and bacteria, that inhibits with the biochemistry of bacterium fungi. Antibiotics many would say is a miracle drug, helping people to extend their life spans by altering the result of the bacterial infection. In the 1920s’ researchers speculated that the average populations life span age to be only 56 years old, now this number has increased significantly
Antibiotic resistant bacteria have become a huge problem; because it is becoming more and more “smart” resulting the bacterium to become used to the medication. Antibiotics kill bacteria causing the illness and unfortunately as well killing off good bacteria that protects the body from infections. This alone is a problem because now the drug resistant bacteria can spread itself by a process called conjugation when a bacterium transfers genetic material from one bacteria to another. The drug resistant has now allowed the opportunity to multiply “grow” and take
Food and Drug Administration (FDA) about 80 percent of all antibiotics sold in the U.S. are being given to animals to make them growth and to avoid diseases. So, every single time people purchase meat at groceries they are potentially exposing themselves to drug resistant bacteria. One very smart decision that people could make to interrupt this process is by choosing antibiotic-free meats, which upon doing research they are available in many groceries stores and restaurants than ever before. Because the food we eat is a one factor to how people are getting drug resistance bacteria. Health professionals are advising people to avoid meats from factory farms that depend on antibiotics to make up for cramped, unsanitary conditions. A practice that can lead to antibiotic resistance. For example, some popular factory farms are “Foster Farms chickens raised this way carried multidrug-resistant Salmonella that sickened 574 people last year.” (Krans 2014). The water and fertilizer that agricultural fields use for the many crops is containing animal feces and drug resistant bacteria. People are eating these crops and are taking even more bacteria that can transform into a drug fighting beast. This bacterium remains inside of our guts, later to mutate into something that no doctor wants to come across with while trying to treat a
In the last decade, the number of prescriptions for antibiotics has increases. Even though, antibiotics are helpful, an excess amount of antibiotics can be dangerous. Quite often antibiotics are wrongly prescribed to cure viruses when they are meant to target bacteria. Antibiotics are a type of medicine that is prone to kill microorganisms, or bacteria. By examining the PBS documentary Hunting the Nightmare Bacteria and the article “U.S. government taps GlaxoSmithKline for New Antibiotics” by Ben Hirschler as well as a few other articles can help depict the problem that is of doctors prescribing antibiotics wrongly or excessively, which can led to becoming harmful to the body.
Resistance arises from mutations that are not under the control of humans, but the evolution of bacteria has been sped along by the overexposure of antibiotics to both people and animals. The number of antibiotic-resistant strains of bacteria in an area is closely related to the frequency that antibiotics that are prescribed (Todar, 2012). Patients often unnecessarily demand antibiotics to treat common colds or simple illnesses that are not caused by bacteria. Instead, these infections are caused by viruses which, unlike bacteria, are unaffected by antibiotics. Incorrect diagnosis can also lead patients to using unnecessary antibiotics, which can sometimes be even more dangerous than otherwise left untreated. Besides the fact that antibiotics kill off beneficial bacteria in the intestines, misuse of antibiotics provides an opportunity ...
Antibiotic-resistant bacteria are created when mutations in the pathogen's genetic code occurs, changing the protein in the bacteria that the antibiotics normally go after into a shape that the antibiotic can not recognize. The average bacteria divides every twenty minutes, so if a contaminated spot has one single bacteria in the morning, there could be trillions on that same spot at the end of the day. That means that when counting all the possibilities of mutations, the amount of mutated offspring that the bacteria might have formed during those replications could be as high as in the millions. Fortunately though, this does not happen so frequently that it is normally an issue. The amount of non-mutated bacteria vastly outnumbers the mutated ones and many of the mutations occurring in the bacteria usually have either a harmful effect, or not effect at all on its function. That means that the pathogen is still relatively less harmful than it c...
According to USA Today, U.S. doctors are prescribing enough antibiotics to give to 4 out of 5 Americans every year, an alarming pace that suggests they are being excruciatingly overused. In fact, Dr. Aunna Pourang from MD states, “to give you an idea of how high the pressure is to prescribe antibiotics, I didn’t get a job once because during the interview I told the lead physician that I only prescribe antibiotic prescriptions when they are warranted.” The development and widespread obsession of antibiotics, or drugs that kill bacteria and thereby reduce infection, has helped billions of people live longer, healthier lives. Unfortunately, the more we rely on and abuse antibiotics, the more bacteria develop resistance to them, which makes treating infections that much more challenging and leads to the growth of drug-resistant strains of bacteria. Research from the Center of Disease Control found that two million people in the United States become infected with antibiotic resistant bacteria, while 23,000 people die from such infections each year. Americans often aren’t informed on the power of the human body and rush to assumptions when perfection isn’t present. In a nutshell, the obsession of antibiotics is quite deadly and needs to be addressed before it’s too
Factory farming is a necessary component of our modern food production and supply system. In 2005, the U.S. produced 45.7 billion pounds of red meat. It efficiently produces and distributes huge quantities of food to feed the growing population of America. But the overfeeding of antibiotics in the U.S. meat industry has gotten to the extreme and it calls for a drastic change in order to prevent a potential public health crises.
One of the many growing concerns in the world today is antibiotic resistance. Antibiotic resistance happens when the bacteria that an antibiotic is made to treat learns how to fight the treatment, and develops a strain of DNA that resists the antibiotic. The resistance is then spread from generation to generation and from one bacteria to another bacteria. The article “Antibiotic Resistance Is Worrisome, but Not Hopeless” states that the misuse and overuse of antibiotics by humans is one of the reasons for the development of resistance but not the only reason. All in all, antibiotics are important to our country's public health. Education is one way that our country could aid the misuse and overuse of antibiotics that leads to resistance. The
Throughout history disease has run rampant taking many lives with every passing day. Finding a cure or even just a tool in the battle has been the main focus of scientist throughout time. This focus is what brought us the discovery of antibiotics. Over the years antibiotics have been misused by patients, over prescribed by physicians and have led to resistant strains of bacteria.
Bacteria that is resistant to antibiotics is a major problem not only for the United States, but worldwide. According to the Centers for Disease Control and Prevention (2012) the cause is related to “widespread overuse, as well as inappropriate use, of antibiotics that is fueling antibiotic resistance”. According to World Health Organization (2013) resistance is a global concern for several reasons; it impedes the control of infectious diseases, increases healthcare costs, and the death rate for patients with resistant bacterial infections is twice of those with non-resistant bacterial infections.
However, health concerned organizations want to ban the use of these products due to the increasing fears that they can cause harm to the consumers. For over 50 years, antibiotics have been added to the food of animals such as poultry, cattle and pigs. The main purpose for doing so is to lower the risk of disease in animals. Farm animals are housed together in overcrowded areas, which are very dirty. The hygiene level can get to such a poor state that they are often in contact with their own excreta as well as excreta of the other animals they are housed with and because of tight single air space they share, the likelihood of catching diseases from one another is further increased and very often a whole heard can be infected at one time.
This turn of events presents us with an alarming problem. Strains of bacteria that are resistant to all prescribed antibiotics are beginning to appear. As a result, diseases such as tuberculosis and penicillin-resistant gonorrhea are reemerging on a worldwide scale (1). Resistance first appears in a population of bacteria through conditions that favor its selection. When an antibiotic attacks a group of bacteria, cells that are highly susceptible to the medicine will die.
The most effective way to combat pathogenic bacteria which invade the body is the use of antibiotics. Overexposure to antibiotics can easily lead to resistant strains of bacteria. Resistance is dangerous because bacteria can easily spread from person to person. Simple methods for preventing excessive bacterial spread are often overlooked. Not all preventative measures are even adequate. Doctors and patients often use antibiotics unnecessarily or incorrectly, leading to greater resistance. Antibiotics are used heavily in livestock and this excessive antibiotic use can create resistant bacteria and transfer them to humans. In order to reduce resistant bacteria,
Thesis: With the advent of antibiotics in 1929 Fleming said, "The time may come when penicillin can be bought by anyone in the shops.Then there is the danger that the ignorant man may easily underdose himself and by exposing his microbes to non-lethal quantities of the drug make them resistant."With the overuse of antibiotics today we have seen this very idea come to be.Over usage is caused most prevalently by a lack of education on the part of the patient.Thus stated, the way to overcome such a circumstance is to educate, not only the patient but also the physician.
Meat cultivation uses more land, water and resources to house, transport, and slaughter animals and their grain and food than it would cost to fund in vitro meat studies. In April 2008 the In Vitro Consortium first met at the Norwegian Food Research Institute. The consortium is “an international alliance of environmentally concerned scientists striving to facilitate the establishment of a large scale process industry for the production of muscle tissue for human consumption through concerted R&D efforts and attraction of funding fuels to these efforts. ”Meat in both its production and its consumption has a number of destructive effects on not only the environment and humans but also live stock. Some of these effects are antibiotic resistant bacteria due to the overuse of antibiotics in livestock, meat-borne pathogens (e. coli), and diseases associated with diets rich in animal fats (diabetes).
It is estimated that over one-half of the antibiotics in the U.S. are used in food animal production. The overuse of antimicrobials in food animal production is an under-appreciated problem. In both human and veterinary medicine, the risk of developing resistance rises each time bacteria are exposed to antimicrobials. Resistance opens the door to treatment failure for even the most common pathogens and leads to an increasing number of infections. The mounting evidence of the relationship between antimicrobial use in animal husbandry and the increase in bacterial resistance in humans has prompted several reviews of agricultural practices by scientific authorities in a number of countries, including the US.
The discovery of antibiotics is attributed to Alexander Fleming who discovered the first antibiotic to be commercially used (Penicillin) in approximately 1928. An antibiotic, also known as an antimicrobial, is a medication that is taken in order to either destroy or slow the growth rate of bacteria. Antibiotics are integral to the success of many medical practises, such as; surgical procedures, organ transplants, the treatment of cancer and the treatment of the critically ill.
