Recommended: War influence on the development of penicillin
Penicillin is an antibiotic used to treat infections and some illnesses in the human body. It was discovered in 1928 by a bacteriologist returning from war. This man’s name was Alexander Flemings, he had seen what infections can violently do while at war and wanted to find a way to treat and save people. It took him many years to even come close to the perfect cure, to where he nearly gave up. One day he was cleaning Petri dishes and found a strange fungi on the platter. Little did Dr. Flemings know that he was about to change the world when he took that fungi into the laboratory to run tests on it. A long time passed till Alexander Flemings found his miracle drug, it took 20 years. Life before Penicillin was hard, violent infections raged
The Black Death (also called the "plague" or the "pestilence", the bacteria that causes it is Yersinia Pestis) was a devastating pandemic causing the death of over one-third of Europe's population in its major wave of 1348-1349. Yersinia Pestis had two major strains: the first, the Bubonic form, was carried by fleas on rodents and caused swelling of the lymph nodes, or "buboes", and lesions under the skin, with a fifty-percent mortality rate; the second, the pneumonic form, was airborne after the bacteria had mutated and caused fluids to build up in the lungs and other areas, causing suffocation and a seventy-percent mortality rate.
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.
One measure they had was that of the “red cross”. This is where they would paint a red cross on the doors of people who were diagnosed with the plague. I think this would have worked because it would let people know who had the plague, so that they could avoid falling ill themselves.
The practice of medicine in medieval times played a very important role in society. The communities and civilizations would not have survived without the treatments that were offered. In order to have kept the population going, medicine was required. The population might have been much smaller, or even tanked without the hope of these medicines in certain cases. If the Black Death had not occurred, most of the advancements in medicine would not have taken place. While this was a devastating event in history and a misery for all of the people affected, it led the way to many new improvements in medicine. Medical recipes were developed which used the resources they had available to create relief for some of the illnesses that affected people at that time and which we still have today. The medical issues that could not be cured with the herbs and resources they had available required surgery. Compared to modern surgeries, medieval surgeries were very different. Surgery was only performed if it was the last resort and there was no other option. They had to use poisonous resources, which could be extremely dangerous. Today, we take for granted the opportunities we have with surgery, and if we need it there is sometimes no thinking twice, as in the case of someone who gets plastic surgery to change the appearance of a part of the body. Although these practices may seem like they have no affect on where we have advanced to today, they in fact do. Without the practice of medieval medical recipes and surgical practices, the medical world would not be where it is today.
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.
Throughout the ages, while the origins to this day continue to be debated, the strength and potency of the disease have rarely been in question. Syphilis, while not viewed as a huge threat due to a decreased number of cases in the mid-late 1990s, needs to be taken more seriously by the public because it is more dangerous than many realize, especially because it is extremely contagious, it is extremely elegant in the symptoms it produces, it has played a larger part in history than many would think, and there is a certain stigma which surrounds the disease, which in turn pushes individuals away from receiving the necessary testing.
The medicinal practices and problems of the Elizabethan Era were very important to the people, although they are very different from those of today. There were many different beliefs and diseases, like the Plague. Medicine was not an exact science and was related to Alchemy (Chemistry). Here, some of the many practices and beliefs of the Elizabethan Era will be discussed.
What does penicillin treat? There are several different kinds of penicillins, and they treat infections caused by bacteria. Each is used to treat different kinds of infections, and one kind of penicillin usually cannot be used to replace another. In addition, bacterial infections in many different parts of the body are treated with penicillins that work by killing the bacteria or preventing their growth. They are sometimes given with other antibacterial medicines.
Medicine in the Middle Ages We are very lucky today! When we are sick, we go and see the doctor, and he or she can usually make us better with the use of medicine. It wasn‘t like this in the medieval era.
Ernest Chain and Howard Florey with the knowledge of Flemings work were able to successfully purify an extract of penicillin for testing. The tested it in 1940 on mice, they concluded that those who were given the penicillin lived whereas the others did not. Later in 1945 all three men received the Nobel Prize for their contr...
The contributions of several doctors, researchers, and scientists helped improve the health of the growing population. In 1850 the average life expectancy was 42 years. By 1910 the average life expectancy had risen to nearly 55 years. Between 1850 and 1910 there were several advances in the medical field. The introduction of genes, white blood cells, blood groups, insulin, rubber gloves, aspirin, and vitamins and the discoveries of Pasteur, Charcot, Halsted, Zirm, Lister, and Koch were the starting point of an international fight against disease.

Alexander Fleming started the history of antibiotics in the 1920's with his discovery of penicillin.When penicillin was first discovered and used widely, it was touted as a wonder drug, and consequently was used as one.Though not necessarily harmful to the patient penicillin was used for much more infections than it was able to combat.Today the same practice is observed in the medical profession, however at this point it is due more to the detriment of an uneducated public.Studies have been carried out that show the huge over usage of antibiotics.In the seventies Soyka et al, concluded, "60% of physicians surveyed gave antibiotics for the treatment of the common cold."[3], and by common knowledge the common cold is a virus, something that cannot be treated by an antibiotic.Nyquist
When antibiotics first began to see widespread American usage in the 1940’s, they were heralded as a miracle drug, a description that was not far from the mark considering the great number of debilitating or fatal illnesses that they could rapidly cure. In a time where bacterial diseases that today carry few serious health risks in healthy adults—such as strep throat, ear infections, syphilis, and wound infections—often led to serious debilitation or death, the invention of antibiotics was among the greatest single improvements in public health ever made. And today, more than three quarters of a century after Alexander Fleming discovered the antimicrobial properties of penicillin, antibiotics are as important as ever in maintaining a healthy population, from their ability to treat common infections to the safeguards they provide patients undergoing surgeries and other infection-prone procedures that could otherwise be too risky to perform. However, today many doctors and researchers are beginning to fear that this golden era of antibiotics may be coming to an end due to the ever-increasing threat of antibiotic resistance. There are a number of practices that contribute to increased antibiotic resistance, including the unnecessary prescription, improper dosage, and incorrect usage of antibiotic drugs by humans. But one of the major potential causes of antibiotic resistance does not involve human patients at all. Rather, many believe that the excessive use of antibiotics in food animals is among the leading threats to the future of human ability to fight bacterial infections.
Hippocrates was a Greek physician that left a legacy that existed during his lifetime in Classical Greece and continues today. His moral and ethical standards were the foundation of his teachings, along with his meticulous writings concerning the study of the human body. He firmly believed that poor health and disease were the result of a natural process that could be discovered and cured through careful clinical reasoning and observations. Hippocrates travelled throughout Greece teaching and describing disease symptoms, and taught doctors how to analyze and treat specific illnesses or diseases. Hippocrates’s accomplishments give him the respect from doctors and medical professionals around the world that continues even today.
