The Penicirin

To begin with, penicillin was accidentally discovered by Alexander Fleming in 1928. As stated in, “The discovery of penicillin: the true story,” ….. Fleming had gone on a month long vacation, and while away, a stray mold spore came through an open window and landed on one of the many bacterial cultures Fleming had not put away before he left.” The series of events leading to the discovery were not all natural. Fleming had put the cultures in a tray of lysol to soak after succinctly looking over. When a former lab member came to visit Fleming. He showed him some cultures and noticed that one looked

In this reading there was many very interesting facts about penicillin. Penicillin was a breakthrough in the medical field in the 20th century. The scientist Alexander Fleming had accidentally spilled a vile of bacteria on to a plate of bacteria to his benefit he found that is had stopped the growth of bacteria. This accidental discover has benefited everyone in the world because we have to get these shots if we are infected, plus it saved many life’s in world war II. However, Penicillin is considered an antibiotic chemical that is created by living organism to stop the growth of bacteria and prevent an illness if people were to come into contact with this problem. Since the discovery and massive stock piling of this cure it has become less

Penicillin is a type of antibiotics. It fights nasty bacteria in a human body. Penicillin is used to help many different infections caused by bacteria. Penicillin was made for the soldiers in world war one, it was to help bullet wound infections and infections caused by lost limbs. Penicillin is made from extracting it from mould.

Antibiotics are inarguably one of the greatest advances in medical science of the past century. Although the first natural antibiotic Penicillin was not discovered until 1928 by Scottish biologist Alexander Flemming, evidence exists that certain plant and mold growths were used to treat infections in ancient Egypt, ancient India, and classical Greece (Forrest, 1982). In our modern world with the advent of synthetic chemistry synthetic antibiotics like Erithromycin and its derivative Azithromycin have been developed. Antibiotics have many uses including the treatment of bacterial and protozoan infection, in surgical operations and prophylactically to prevent the development of an infection. Through these applications, antibiotics have saved countless lives across the world and radically altered the field of medicine. Though a wonderful and potentially lifesaving tool, antibiotic use is not without its disadvantages. Mankind has perhaps been too lax in regulation and too liberal in application of antibiotics and growing antibiotic resistance is the price we must now pay. A recent study showed that perhaps 70% of bacterial infections acquired during hospital visits in the United States are resistant to at least one class of antibiotic (Leeb, 2004). Bacteria are not helpless and their genetic capabilities have allowed them to take advantage of society’s overuse of antibiotics, allowing them to develop

In 1928 Dr. Alexander Fleming began to sort through a pile of petri dishes containing colonies of bacteria that causes boils, sore throats, and abscesses. As he sorted through the dishes he noticed something unusual on one dish. It was dotted with colonies, and one area had a blob of mold growing. The area of mold was later identified as a rare strain of Penicillium notatum, the mold had secreted something that inhibited bacterial growth. Fleming later uncovered that this mold was capable of killing a wide range of harmful bacteria such as streptococcus, meningococcus and the diphtheria bacillus, that had played humanities. Prior to the discovery of Penicillin, Sulfa drugs were used during World War II. These drugs were name as the “wonder drug”. Although they’re still used today, Sulfa drugs were used to cure bacterial infections such as UTIs and gonorrhea. The new found drug penicillin, would cure millions and replace the use of Sulfa drugs.

Jesse Lane says in Not-So-Dumb Luck, When he came back, he noticed that every dish he had left out in the open was covered in mold.” She later says, “The dish that had caught Fleming’s eye contained a staphylococci culture- in other words, it was chock full of bacteria- and while Fleming had been away, the culture had also grown a tuft of yellow-green mold.” And that was the beginning revolutionary history of penicillin. Later in the paragraph the author says, “After some experimentation, he found that the ring was bacteria free, and that the mold was a rare spore called Penicillium notatum,” Where the name penicillin comes from ”which had wafted on air currents into his lab from another floor.” If he hadn’t gone on vacation and left his lab a mess then penicillin wouldn’t be with us today saving lives.Thirdly, penicillin is a widely used medicine that kills bacteria and treats

One of the earliest discoveries involving medicine, has saved many lives and healed many wounds. This medicine is Penicillin and we are proud to say that the medicine is still working around the world. Penicillin might have been an accident, but has been one of the best accidents to ever happened. Penicillin saved many soldiers during the war in Germany, and was thankfully mass-produced to the public. If it weren’t for Penicillin many people that struggled with illnesses might have not made it through that time in their life. Penicillin has shaped our world

Before Alexander Fleming founded penicillin,a French medical student Ernest Duchesne first noticed penicillin. In 1897, he first recorded his finding on a piece of paper differentiating molds and microbes. Ernest first came across clues for developing penicillin when he was in the Military Health Service School in Arabia. He saw that the stable boys at the hospital kept their saddles in dark and damp rooms to intentionally let mold grow.When Ernest ask the reason for these peculiar actions, the stable boys told him that the mold would heal the saddle sore on horse.Ernest then take this information and decided to test it on guinea pigs. Ernest Duchesne extracted substances from penicillium glaucum and successfully cured typhoids in guinea pigs,

Instead, multiple systems and different processes are known to be involved in creating a reaction. Drug allergies as a whole are known to be plastic, or the phenotype can change depending on the environment (Doña et al., 2014). There are numerous forces that must interact to spark a reaction. To analyze the root cause of an individual’s allergy, there are multiple variables that must be taken into account. Some mechanisms that are known to play a role in the occurrence of allergies, and specifically penicillin allergies, include the environment, drug availability, an individual’s antibiotic uses and genetics. Penicillin has been in existence for less than a century, so natural selection has had a limited amount of time to be involved in the selection for genetic traits. It can be hypothesized that penicillin allergies are the result of complex genetic and environmental causes that have been selected for in an environment that lacked the presence of modern day antibiotics. As a result, different populations have evolved independently to have unique casual mechanisms and susceptibility to penicillin

Since the inception of penicillin, many synthetic penicillin have been developed to treat problem with resistance”. In addition, penicillin is a class of antimicrobial drug that is used to treat infections including respiratory infections, urinary tract infections, and sexually transmitted disease. Also, they are effective for treating infections of the heart that are caused by bacteria. Beta-Lactam Antibiotics effective in treating polymicrobial infections. They are effective in treating intra abdominal and gynecologic infections. Cephalosporin’s are similar to the penicillin and can be divided into four generations based on the antimicrobial spectrum activity. The first generation were the first class that was utilized and used to treat skin infection, urinary tract infections and preventive measure for surgical procedures The second generation was used to treat community acquired pneumonia, and other respiratory infections. The third was used to treat bacterial meningitis and nosocomial infections (Arcangelo & Peterson,

Penicillin has had an enormous effect on society. One of the most famous examples of serendipitous science in the 20th century and what some would consider a miracle, penicillin constantly effects society to this day. This discovery saves lives every day and has for almost eighty years. This discovery is scientifically unique and ideal as a medication, even if surrounding circumstances aren’t always ideal.

“Over 50,000,000 peoples lives have been saved by the drug penicillin” (Sim). Today Penicillin and other antibiotics are crucial in the lives of people. One bad thing about penicillin is approximately 11.5% of the population is allergic to it so the diseases they receive that have to be healed by penicillin or other antibiotics might not heal as fast or maybe even kill them. Another negative aspect to Penicillin is it weakens the immune system(Cooper). Most of the body survives off of friendly bacteria and if antibiotics kill bacteria in large numbers, then it kind of defeats the purpose. Penicillin is used to treat many diseases and viruses that can be deadly if medicine was not applied, and they are easily accessible. After the discovery and processing of Penicillin, it was often described as the “Miracle Drug” and that is exactly what it was. Prior to the foundation of Penicillin, death was very common due to diseases that we think are no

Penicillin, scientifically named Penicillium Notatum, is a antibiotic used for killing bacteria. It can be used to cure scarlet fever, ear, skin and throat infections. It has come along way from where it started in 1896. Penicillin has become so accessible today through the help of the doctors and research associates who studied it.

Penicillin is a very effective medicine and in the article “Not-So-Dumb Luck” it states that “When a bacteriologist Alexander Fleming left for vacation one day in September of 1928, he left a mess in his laboratory.” When he came back all the dishes he left out were covered in mold. One of Flemings dishes was covered in bacteria and a “Penicillin

Penicillin G is a naturally occurring penicillin that works against gram-positive bacteria but is less effective on gram-negative bacteria. There are other chemically modified penicillin that are more effective against gram-negative bacteria. Penicillin is a beta-lactam antibiotic, and has three structural requirements. There
