An Evolving Epidemic Head scientist of the antibiotic research center at McMaster University in Hamilton, Ohio, Gerry Wright, has studied the genes of 500 streptomyces strains, a type of bacteria, many of which had never previously been identified. All 500 strains held antibiotic-resistance genes and on average were resistant to 8 of 21 tested antibiotics (Sachs). With an average resistance rate as high as 67 percent in some of these streptomyces species, it is evident that antibiotic-resistance is a rising problem. Regardless of the countless studies proving antibiotic-resistance and articles about the subject, it is one the public knows little about. With such a history of antibiotic benefits, it is difficult to perceive the negative affects these drugs have. This is the main reason antibiotic studies are disregarded. If the large majority of the population continues to do little to avert antibiotic-resistance, bacteria will evolve beyond medical treatment. Actions must be taken by the community as a whole, and even further by the individual, to “reduce the spread of microbes and improve our defense against them” (Schmidt 272). Although antibiotic resistance is inevitable, humans are accelerating the natural defense of microbes through the overuse and misuse of antibiotics. The natural components of antibiotics have been used as local remedies long before humans understood the reasons why these sometimes-radical treatments worked. Penicillin became the first manufactured antibiotic after physician Alexander Fleming published articles regarding this bacteria-disabling mold in 1928. Come 1932, penicillin was commonly used to treat infected war injuries, saving the lives of unnumbered soldiers (Lewis). Since then, penicillin has b... ... middle of paper ... ...rding the importation of food products and live animals, other organisms which carry bacteria. In a world governed by international relations, travel is a large part of today’s society. The leisure and significance of world travel is unlikely to depreciate. Therefore, local communities must take actions regarding antibiotic-resistance, whether they are awareness programs or state and nationally regulated laws. The act of hindering antibiotic-resistance development is also an individual commitment. People must understand the effects of excess antibiotics and commit to making a difference. These acts may be as simple as not demanding unnecessary antibiotics and finish the entire course when antibiotics are prescribed. Regardless to the natural evolution of bacteria, society must delay the development of antibiotic-resistance within bacteria with humanity has hastened
The Factor of War in the Development of Penicillin The discovery, development and subsequent use of penicillin can be considered to be one of the most important breakthroughs in medical history. There were many factors, which were involved in the development of penicillin, and it could be argued that war was the most important, but other factors were also responsible. Alexander Fleming was working in London as a bacteriologist in 1928 when he noticed that a growth of a mould called penicillin produced a substance that actually killed the germs he was working on. He realised that this might be very important and a year later he wrote an article about his findings. However, Fleming did not have the facilities or the support to develop and test his idea that penicillin could fight infection, and he didn't develop it further.
Penicillin, derived from the mold Penicillium, is the first antibiotic to successfully treat bacterial infections on humans. It was accidentally discovered by scientist, Alexander Fleming. While Fleming was growing Staphylococcus, a serious and often deadly infection, in a dish, he noticed the bacteria had stopped growing after a mold found its way
Bacterial resistance to antibiotics has presented many problems in our society, including an increased chance of fatality due to infections that could have otherwise been treated with success. Antibiotics are used to treat bacterial infections, but overexposure to these drugs give the bacteria more opportunities to mutate, forming resistant strains. Through natural selection, those few mutated bacteria are able to survive treatments of antibiotics and then pass on their genes to other bacterial cells through lateral gene transfer (Zhaxybayeva, 2011). Once resistance builds in one patient, it is possible for the strain to be transmitted to others through improper hygiene and failure to isolate patients in hospitals.
Years later other scientists were also intrigued by the possibilities of penicillin and produced enough penicillin to prove that it was a useable antibiotic. The scientists from Great Britain were developing all of this during World War II, and unfortunately funding for their drug was unavailable due to the war. They decided to bring their concepts to the United States, and once enough was made, it was eventually used, to treat wounded soldiers during World War I.
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
Antibiotic resistance is one of the most important issues facing health care today, with wide reaching future implications if abuse continues. In the United States alone, antibiotic resistance is responsible for over two million illnesses and 23,000 deaths per year. Providers need to be judicious in the disbursement of these life saving pharmacological agents, while being informative of why antibiotics are not always the answer (Talkington, Cairns, Dolen, & Mothershed, 2014). In the case listed below, several issues need to be addressed including perception, knowledge deficit, and the caregiver’s role. This paper will focus on whether a prescription for antibiotics is appropriate and other courses of action that may be taken instead.
Penicillin, the first antibiotic, was discovered accidentally by Sir Alexander Fleming in 1928. Sir Fleming was growing bacteria on agar plates and accidentally left one of the plates open. A mould started growing on this. Fleming noticed that no bacteria grew
“The World Health Organization projects that as drug effectiveness decreases and antibiotic resistance increases, public education becomes more and more crucial” (476) Antibiotics were discovered in 1940 and since have been abused and misused. Between bad practices and lack of proper education antibiotic resistance has been allowed to occur. The only way to combat bacterial infections is with strong patient education and following the correct schedule in taking antibiotics.
Antibiotic resistance evolves naturally through natural selection via random mutation, but it could also be engineered by applying an evolutionary stress on a population. The antibiotic action is an environmental pressure; those bacteria which have a mutation allowing them to survive will live on to reproduce. They will then pass this trait to their offspring, which will be a fully resistant generation. Studies at the Finnish Academy found that using one type of antibiotic increases the resistance of bacteria to other types of antibiotics as well. Antibiotics do not work against illnesses t...
...earch in this area. Plus, we also need to become better consumers for our own personal antibiotic use because bacterial infections can also derive from misuse and overuse of an antibiotic drug. We must prevent the spread of bacteria by washing our hands, fruits, and vegetables. Even raw eggs and undercooked meat are suspects in creating bacterial infections. Furthermore, to be properly vaccinated is a major fight against such infections. So “although humans are not yet close to winning the war against S. aureus, these measures may help provide the weapons we need to have a fighting chance” (Freeman-Cook and Freeman-Cook 2006). Perhaps, one day in the near future the fight against bacterial infections will be resolved and there will no longer be a need for posing the hypothesis of “Why Methicillin-Resistant Staphylococcus Aureus (MRSA) is antibiotic-resistant.”
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.
Misuse or overuse of antibiotics plays a key role as to why bacteria have become resistant to antibiotics. With antibiotics easily available these days people will s...
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.
