Once the miracle drug, was introduced, the amount of illnesses had decreased by hundreds, even thousands before penicillin, people (especially the egyptians and the chinese) used extracts from plants and mouldy bread to clean wounds and cure illnesses, because they knew of the antibiotic properties. Penicillin essay penicillin essay 3886200671195diagram one: penicillium notatum producing penicillin00diagram one: penicillium notatum producing penicillin penicillin is a drug, which helps cure bacterial diseases and illnesses. Penicillin was a miracle drug that was now available for the treatment of conditions caused by infection - like osteomyelitis sulfa drugs had stopped the bone disease in '42, but still a hip fusion was needed. Antibiotic resistance is a global threat, and the us center's for disease control and prevention (cdc) considers antibiotic resistance one of their top concerns infections with drug-resistant bacteria may lead to longer and more costly hospital care, and may increase the risk of dying from the infection. Alexander fleming, a world renowned scottish scientist and noteworthy medical figure is widely known for his 1928 discovery of penicillin, a drug that is used to kill harmful bacteria (antibiotic) his work in the following studies, immunology, bacteriology and chemotherapy, is considered medically and historically impacting and highly influential.
Amazingly yesterday a miracle antibacterial drug called penicillin was discovered, at st alexander fleming was looking at one of his specimens of staphylococcus aureus (a bacteria) and he noticed there was a mold growing that is called penicillin. However, according to the centers for disease control and prevention, unnecessary use of antibiotics is a large factor in the emergence of antibiotic-resistant strains of bacteria there are many misconceptions about antibiotics. Penicillin has been considered a miracle drug by doctors ever since it was first used in 1942 it could cure nearly every disease that it was prescribed for and was the cause of a major turning point in world war 2. Penicillin was discovered in london in september of 1928 all medicine by discovering the world's first antibiotic, or bacteria killer producing what became known as the wonder drug.
Miracle drug, curing infectious disease and saving millions of lives in 1945, sir alexander fleming, ernst chain, sir howard florey were awarded the nobel prize in physiology or medicine for the discovery. In an attempt to defeat penicillin-resistant strains, scientists developed methicillin, a different antibiotic in the penicillin class that could work against resistance but within a year, bacterial strains developed resistance to methicillin too — eventually called mrsa , methicillin-resistant staphylococcus aureus , or s aureus. The mold that had contaminated the experiment turned out to contain a powerful antibiotic, penicillin however, though fleming was credited with the discovery, it was over a decade before someone else turned penicillin into the miracle drug that has helped save millions of lives.
According to saver (2008), antibiotic resistance undermines a drug's ability to treat illness problems with resistance can develop insidiously, as bacteria evolve, adapt, and otherwise change over time so that a medication previously thought useful in controlling the bacteria no longer proves effective (p 432. Fleming also discovered very early that bacteria developed antibiotic resistance whenever too little penicillin was used or when it was used for too short a period almroth wright had predicted antibiotic resistance even before it was noticed during experiments. Since 1928, when sir alexander fleming observed that a substance in mold could kill a number of disease causing bacteria, penicillin has been the savior of multitudes of lives through the development of antibiotic medicines and technologies, the uses of this highly effective cure spread worldwide and were used generously for decades. The revolutionary first antibiotic, penicillin20 in earlier years, other scientists were able to grow bacteria, but didn't have enough studies to receive support from institutions fleming took it to the next level, and pushed the envelope.
Antibiotic resistance even before the extensive use of penicillin, some observations suggested that bacteria could destroy it by enzymatic degradation (abraham and chain, 1940. Antibiotic resistant bacteria bacteria's are one-celled organisms that were discovered in 1676 by anthony van leeuwenhoek many people like to define bacteria as a germ, but in reality germs are a form of bacteria. When penicillin was introduced to the public in 1944, it was hailed as a miracle drug, a silver bullet that killed bacteria but left the body unharmed however, alexander fleming, the man who discovered penicillin, isolated bacteria in his laboratory that developed resistance to the antibiotic. Penicillin (pcn or pen) is a group of antibiotics which include penicillin g (intravenous use), penicillin v (use by mouth), procaine penicillin, and benzathine penicillin (intramuscular use) penicillin antibiotics were among the first medications to be effective against many bacterial infections caused by staphylococci and streptococci.
Today, more than 24 percent of gonorrheal bacteria in the us are resistant to at least one antibiotic, and 98 percent of gonorrheal bacteria in southeast asia are resistant to penicillin 1 infectious bacteria are much harder to control than their predecessors were ten or twenty years ago. But it was not until 1928 that penicillin, the first true antibiotic, was discovered by alexander fleming, professor of bacteriology at st mary's hospital in london returning from holiday on september 3, 1928, fleming began to sort through petri dishes containing colonies of staphylococcus, bacteria that cause boils, sore throats and abscesses. Antibiotic resistance does not mean the body is becoming resistant to antibiotics it is that bacteria have become resistant to the antibiotics designed to kill them terms on cdc's website, antibiotic resistance is also referred to as antimicrobial resistance or drug resistance. Antibiotic, bacteria, disease - penicillin: the miracle drug the discovery and development of penicilin essay - penicillin has been considered a miracle drug by doctors ever since it was first used in 1942.
The prevalence of antibiotic resistance in different countries layered according to the history of the introduction of antibiotics to their markets: in mexico, multi-drug resistant shigella were most commonly resistant to the sulfonamides introduced in the 1940s, followed, in descending frequency of incidence, by resistance to penicillin. Discovery penicillin has been used throughout history to fight disease, but it was not until 1928 that it was officially discovered in 1928, alexander fleming was conducting a laboratory experiment, and incidentally ran into the fact that the penicillium fungus had strong antibacterial properties. Penicillin was the first antibiotic, discovered accidentally from a mold culture presently, over 100 different antibiotics are available in the market to cure minor discomforts as well as lifethreatening infections.
Using antibiotics when you don't need them, or not using them properly, can add to antibiotic resistance this happens when bacteria change and become able to resist the effects of an antibiotic this happens when bacteria change and become able to resist the effects of an antibiotic.
