Penicillin and its Impact on Microbiology

Penicillin has saved many lives past and current. “Before the discovery and use of penicillin, infectious diseases had been the leading cause of death throughout history. Furthermore, the therapeutic tools available for treating infections were few and of limited use.”(Kardos 2011) Penicillin has been the drug of choice when treating many diseases.
Even though there are people allergic to penicillin, and bacterias that have formed resistance to penicillin and other antibiotics, penicillin will always be relevant to the studies of Microbiology. From its accidental inception penicillin has made an impact on science, because Alexander Fleming unwavering passion for discovering the body 's natural defense, although he accidentally stumbled upon penicillin, and penicillin has been beneficial from it 's inception in 1929 to present day. From its accidental inception penicillin have made an impact on science, because Alexander Fleming unwavering passion for discovering the body 's natural defense, although he accidentally stumbled upon penicillin,. Following the war, Fleming decided to continue his study as a bacteriologist and accepted an unwavering passion for analyzing the bacteria that caused the infection during the war. In the 1920’s after that the war, Fleming extracted his secretions to culture. Subsequent the results of the culture Fleming substantiated lysozymes where the body’s natural defense against microbes.Fleming later realized that lysozymes effects were limited. The details provided expounds on how the first world war impassioned him to pursue further studies as a bacteriologist that ended with him discovering lysozymes. Fleming returned after a month long vacation in August or early September, and noted a concerning anomaly(Sun, 2005). Fleming observed that many of the culture plates that he left behind had developed some yellow stuff within the mold, and that substance was controlling the growth of the bacteria (Sun, 2005). Fleming decided to observe the random substance in the culture dish closely (Sun, 2005). Fleming realized that Staphylococcal colonies exhibited lysis, which is the dissolution or destruction of cells by lysins for part of the distance throughout the growth of the mold (Sun, 2005). Fleming reported, "But from the previous experience, I would have thrown the plate away, as many bacteriologists must have done before. This important detail that goes well into how Fleming stumbled upon his discovery of penicillin accidentally where he found his culture plates with the mold in it. There are people allergic to penicillin, and bacterias that have formed resistance to penicillin and other antibiotics, penicillin will always be relevant to the studies of Microbiology.(“Penicillin Allergies.”) Penicillin allergy is the most commonly reported medication allergy, either by the

Severe past reaction, such as anaphylaxis, and anaphylaxis allergy is critical, and re-exposure will warrant adverse and possibly mortality. However, for patients with a secondary or uncertain reaction, not rendering penicillin may perhaps be withholding the first result of effective treatment.(“Penicillin Allergies.”) Penicillin is the treatment for Gonorrhea, Syphilis, and Pelvic Inflammatory Disease. (“Penicillin Allergies.”)
The treatment of penicillin is a first line defense encountering some infectious agent that can lead to peril in one 's life. The first line defense is nothing else will do at the time but penicillin. Many physicians perform assessments to check the level of allergy by continuously monitoring the patient after the initial dose(“Penicillin Allergies.”).

However, in the late 1930s, when Chain and Florey began to test antibacterial substances, they used a culture of Fleming’s mold that had been maintained at Oxford. Chain found it was an enzyme which attacks a specific bacterial structure. While reviewing the literature on lysozyme, Chain came across the paper by Fleming, published in 1929, describing the chance discovery of a Penicillium mold that apparently dissolved pathogenic bacteria in its vicinity. Chain also found a culture of Fleming’s mold in the School of Pathology. In 1941 it was considered that there was enough penicillin for a limited trial in patients at the Radcliffe Infirmary under the direction of Charles Fletcher. The first case treated, on 12 February 1941, was Albert Alexander, a 43-year-old policeman, who was moribund with overwhelming staphylococcal and streptococcal

    Penicillin is an antibiotic that was naturally produced by mold and is now used as a medicine all across the world today. It was one of the earliest discoveries when it was accidentally discovered by a scientist in 1928. Penicillin was an accidental discovery that was found in Fleming's lab. In the three articles “Not so Dumb Luck” by Jesse Lane, “The history of Penicillin” by Mary Bellis and “The Discovery of Penicillin” by Brittany Connors, the authors will show events that led to the discovery and development of penicillin and how it is used today. Even though Penicillin was an accidental drug/medicine, it was an amazing series of events that led up to the great use of the medicine today.…

    Penicillin, one of the major inventions of the 1920s, was incredibly useful against fighting off bacterial infections that were fatal to people before, but according to the article “Synthesis and Biological Activity of Antimicrobial Agents, 2nd Volume,” “.The misuse and abuse of antibiotics ended up with microorganisms’ adaption and resistance to an increasing number of them” (Carvalho). Due to people misusing penicillin antibiotics because they did not know the effect it would have, strains of bacteria became resistant to penicillin antibiotics, deeming them useless towards certain strains, some could even say that these antibiotics caused more harm than good in the end. Although, as said in the article “Penicillin,” “Some types of bacteria were not susceptible to it to begin with, and certain strains of staphylococci were found to produce an enzyme, penicillinase, capable of destroying the natural antibiotic”. Even though there were bacteria that were resistant, there were already bacteria that were resistant to penicillin antibiotics to begin…

    Results After testing the absorbance of Control and Treatment with Penicillin and Streptomycin cultures over a 160-minute time period, three phenomena for the three different cultures were recorded and made into the graphs below. An upward trend of the absorbance in the Control culture as time progresses can be observed. Compared to the upward sloping absorbance curve of Control Treatment, both absorbance curves of Penicillin Treatment and Streptomycin Treatment have different directions of trends after 80 minutes the treatments were added. For the culture with Penicillin treatment, before the treatment was added, the absorbance increases at a steady rate until 80 minutes; it started and kept decreasing after 80 minutes, which is the time Penicillin was added. For the culture with Streptomycin treatment, the trend shows that absorbance increases at a steady speed prior to 80 minutes, but after the 80 minutes, which is the time the Streptomycin was added, the rate of absorbance increases at a decreasing rate.…

    Most people also tolerate penicillin very well, though a small number of people are allergic ("Penicillin allergy - Symptoms and causes", 2018). As you may know, bacterial cells have cell walls containing peptidoglycan. When bacteria divide, holes actually appear in their cell walls that must be filled with peptidoglycan. However, penicillin inhibits proteins that are needed to link the peptidoglycan together.…

    But with bacteria becoming more and more resistant to penicillin it is almost becoming obsolete due to how strong the bacteria. For example the bacterial disease MRSA is caused by a bacteria resistance to any antibiotic. MRSA is incurable by any antibiotic. Another drawback for penicillin is that about ten percent of the world’s population is allergic to the antibiotic, but only about .03 percent of the world’s population is fatally allergic to penicillin, but penicillin is still useful for minor infections, at least for…
