The Discovery of Antibiotics

The third and final factor in bacterial resistance to antibiotics is bacterial genetic exchange. It is very common for bacteria to share genetic info between cells even if the bacteria are not the same species. When this happens, genes and DNA get mixed into different species allowing more mutations against the antibiotics.

Antibiotics, composed of microorganisms such as streptomycin and penicillin, kill other infectious microorganisms in the human body. At one point, antibiotics were considered to have “basically wiped out infection in the United States”, but due to their overuse and evolutionary

The wonderful discovery of Penicillin, a medicine that was discovered in 1928. This medicine was used to cure bacteria in humans. Penicillin had good results not only in the 1928, as it also still is very successful today. Penicillin had a big impact, it cured many people in the U.S. during World War II. penicillin,leads to the development of others antibiotics.

The discovery of penicillin was one of the most important discoveries in the 1900s and marks a turning point in human history. Penicillin was one of the world’s first antibiotics which eventually evolved into modern antibiotics that are used today; it has often been described as a miracle drug. The discovery of penicillin meant that doctors finally could completely cure their patients of deadly diseases. After World War I, many soldiers died from infected wounds because the antiseptics used, killed the patients’ immunological defences more than they killed the invading bacteria. Penicillin kills bacteria by destroying the cell wall of the microorganism causing the cell to burst; it was very effective in clearing bacteria without harming the

The disclosure by Alexander Fleming of penicillin opened up a totally new time of chemotherapy. Antibiotics are the chemotherapeutic specialists that kill or inhabit the development of microorganisms. These substance operators are utilized to treat malady by wrecking pathogenic microorganisms or restraining their development at focus sufficiently low to enough to avoid undesirable harm to the host (Dafale et al., 2016).

The onset of World War II made the drug very essential to the recovery of soldiers. It prevented millions of deaths and amputations, and the number of units sold in the United States increased from 400 million to 650 billion units per month in just two years. The number of casualties would have been drastically larger without penicillin since minor injuries would have proliferated into fatal infections. This antibiotic not only had short-term effects, but also had long-term effects since penicillin remains the most widely used drug today. Strep throats can be easily and cheaply treated now, but around seventy years ago, people would have died because of this

Antibiotics were introduced to people in 1929, which could restrain the normal growth of the other bacteria called antimicrobial activity, was found by British scientist Alexander Fleming by coincidence. Then scientists used antibiotics, to cure injured soldiers and got great success during the World War. With the efforts of many scientists in the past half of the century, thousand kinds of antibiotics are found, which could be natural, semi-synthetic or synthetic, and many of them are used in medical field successfully.

Penicillin is an antibiotic medicine used to treat harmful bacteria and infections inside and outside of your body. Alexander Fleming, a bacteriologist, discovered it in the early 1900s. As stated by Brittany Connors on page 125 of “The Discovery of Penicillin: The True Story”, “Fleming often admitted that he discovered Penicillin by accident, and that all of the work was done by nature.” Although the finding of this cure may have been an accident, it’s use case has helped save many lives and keep many from sickness. There were numerous events that led to the discovery and development of this treatment such as Fleming’s messy laboratory, Florey’s realization of the medical potential of Penicillin, and Moyer’s success in raising the production yield.

“In 1938, Howard Florey and Ernst Chain began to study penicillin” (Connors 126). This is important because it means extensive research was being done to figure out a way for penicillin to be applied on humans. “Part of the reason for their increased effort in discovering how penicillin could be used on humans was that a drug was needed to reduce bacterial infections in soldiers’ wounds” (Connors 126). This means there was a need for the development of penicillin, this fact probably motivated the scientists. In the end, without the development of penicillin, it could not have become such a widely used

In the mid 1900’s, illnesses swept through the city of London and consumed the lives of many unknowing citizens. Any sickness or open wound was susceptible to a fatal infection, which led the body to be taken over by millions of harmful bacteria (Fogel). Thanks to Alexander Fleming’s encounter of penicillin, we no longer have to worry about this. Penicillin serves as a life-saving, bacteria killing drug that is responsible for the lives of millions. Plus, it played a major role in furthering the effectiveness of medicine. Alexander Fleming’s miraculous discovery of penicillin saved a countless amount of lives and was the basis for progressing medicine.

Widespread use of antibiotics has been very controversial in the media as well in the general population. Due to these controversies, it is very misunderstood to how antibiotics work leading to many patients in the hospital setting wanting to take them when it is not necessary or refusing to take when it is necessary for their survival. Some of this controversy is due to antibiotic resistance, which has spread an alarming rate in the 21st century (Walsh, 2000). Antibiotic resistance is the result of very strong bacteria or microbes that are resistant to the antibiotic prescribed and those microbes accumulate overtime by their survival, reproduction and transfer, leading to increased levels of antibiotic resistance.

These mutations, no matter what process that has led to their occurrence, block the action of antibiotics by interfering with their mechanism of action (1). Currently, antibiotics attack bacteria through one of two mechanisms. In both mechanisms the antibiotic enters the microbe and interferes with production of the components needed to form new bacterial cells. Some antibiotics act on the cell membrane, causing increased permeability and leakage of cell contents. Other antibiotics interfere with protein synthesis in cells. They block one or more of the steps involved in the transformation of nucleic acids into proteins.

Many people have died in the past due to infectious diseases. A human with an infection creates another organism which reproduces inside them. Like the pest, one of the most famous diseases killed millions of people in the 14th century. The only way to kill or stop the growth of an infection or bacteria is with antibiotics. The first antibiotic ever created was the penicillin and the greatest one till now. This drug was discovered by Alexander Fleming in the 1920´s but it was introduced in the 1940´s. Scientist began testing penicillin on lab rats but eventually, it was tested in humans. A man contracted a severe infection from a scratch on his face and Penicillin was given to him where he improved dramatically. After World War II, scientists

New discovery of antibiotics has slowed down and the select number of pathogenic bacteria in existence are continuing to increase in virulence due to increased exposure. Although advances have been made to address the issue of bacterial resistance to antibiotics, remaining exist that may not be as obvious a threat to fighting especially virulent bacterial

Penicillin was first discovered in 1928 and quickly became known as a miracle drug. Penicillin’s areas of largest significance fall into three categories and this essay will briefly outline how Penicillin’s discovery contributed historically, scientifically and in the military, particularly in the Second World War.
