Dr. Howard Florey Report

Early in the 1920s in London halfway through an experiment with staphylococci bacteria,a young British bacteriologist Alexander Fleming went on vacation. After coming home from two month vacation he noticed some strange mold in unwashed glass dishes where he did his experiments. He also noticed that near mold was a clear ring where no bacteria were growing but further away bacteria were normal. Something killed that bacteria and he thought that this might be important. Fleming worked hard on his mold. He squeezed some juicy mold which he called penicillin. But he couldn't get enough penicillin and couldn't prove that it would kill bacteria and make people healthier. . In the newspapers they wrote what he said: “One sometimes finds what one is not looking for. When I woke up just after dawn on

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

A group of Oxford scientists built upon the discovery by Alexander Flemming in order to mass produce penicillin. In the course of his research, Sir Flemming noticed that the secretions of a certain strain of mold, Penicillium notatum, killed surrounding bacteria. The purification of penicillin from the secretions, however, proved difficult. In the late 1930s, Howard Florey, Ernst Chain and others at Oxford University, “turned penicillin from a laboratory curiosity into a life-saving drug” (American Chemical). For their work on penicillin, Flemming, Florey and Chain were awarded the 1945 Nobel Prize in Physiology or Medicine. The first penicillin samples were unrefined and produced in milk jugs (Quinn, 427), but within five years, its distillation occurred at the industrial level. This was accomplished as a result of the implementation of an open network of information exchange. Roswell Quinn writes, “Mold samples, top-secret reports, and scientists began flying all over the country and, in some cases, the world” (Quinn, 427). Additionally, the cost of the drug’s development raised no concerns

Have you ever wondered how the discovery of penicillin changed the world for the better. Penicillin has changed the world in a positive effect helping the world cure some diseases and illnesses that people have a hard time living with. Some diseases that penicillin cures is :strep throat, scarlet fever, diphtheria, syphilis,gonorrhea, meningitis, tonsillitis, rheumatic fever and many more diseases are cured by this fantastic discovery of medicine. The founder of penicillin is Alexander Fleming and he founded it during world war two but the year was 1941.

Penicillin, known as the mistaken drug, was created, “when bacteriologist Alexander Fleming left for vacation and left a mess in his laboratory,” as it states in “Not-So-Dumb Luck”.

Howard Florey is an Australian Pathologist and Pharmacologist who discovered the properties of Penicillin. Penicillin is a group of antibiotics produced naturally by blue mold. And due to his discovery of the properties of Penicillin and its ability to cure various infectious diseases such as pneumonia and blood poisoning, which were deadly diseases that died from during the second world war. Howard Florey was a born on the 24th of September, 1898 in the South Australian capital, Adelaide, his parents were Joseph Florey, a boot manufacturer from England and Bertha Florey a native-born woman, He was the youngest in his family of eight children. During his early life, Howard Florey was found academically brilliant, he attended collage at the

In 1928, Scottish scientist Alexander Fleming discovered penicillin for the first time. His discovery was an accident: he was in his laboratory and noticed that a window had been left open overnight. A Petri dish containing Staphylococcus bacteria was now growing blue-green mould.

In September 1928, a few months after appointed as professor of bacteriology he returned back to his laboratory from a long break with his family and accidentally noticed that a culture plate of staphylococcus aureus had been defiled with small pieces of mold. He also discovered that there were settlements of staphylococci inside the culture plate was not there. He then discovered the they had been destroyed by the piece of mold. Fleming immediately started to investigate thinking that he had found a very powerful enzyme; he called the enzyme mould juice but later then changed it to penicillin. Moreover only did he realize after many years that his accidental discovery of a bacteria killer changed the course of history and revolutionized medicine forever. Fleming discovered that his discovery was capable of killing a wide range of harmful bacteria. For the advancement of his discovery, Fleming immediately called two former teachers that then became his assistants to help him extract pure liquid from the piece of penicillin. Unfortunately many efforts they all failed but Fleming produced and distributed his discoveries in the British Journal of Experimental Pathology in 1929 with his discoveries conveying the benefits of penicillin and talking about how they can be used theoretically in the future. As the result of Fleming discoveries and beliefs, a group of men from Oxford University led by a few scientists completely extracted and completed separated liquid penicillin. The antibiotic extracted eventually came out for the public and was used in World War II changing battlefield medicine and the saving the lives of many soldiers. In 1945, Alexander Fleming, and the scientists from Oxford University all received the nobel peace prize for discovering penicillin. In 1946, Fleming received head of the Saint Mary’s Inoculation Department and became

The Penicillin, what most people use, is one of the most popular medicines used for people that are sick or are old. And it was discovered on accident by a bacteriologist named Alexander Fleming. Because of what led to discovery also led to the early development and later development of his accident invention.

Have you ever wondered how does medicine works and how was it discovered? Alexander Fleming was a bacteriologist that went to St Mary’s Medical school. Fleming had many marvelous discoveries such as penicillin. Fleming served many wars as a medic and bacteriologist. Alexander Fleming discovered penicillin, which is a fungus, to make the first medicine.

Penicillin was discovered by accident in 1928 by Alexander Fleming. After leaving bacteria containing Petri dishes in a lab over a weekend they became contaminated with mould. Alexander Fleming realised that the bacteria calls around the mould were dying. It was through further testing that he realised the mould was creating a substance that destroyed bacteria, which he later called Penicillin.

Did you know penicillin was founded when a scientist named,Alexander Fleming went away on a vacation, and left his lab unclean.When he came back from his vacation, Mr.Fleming noticed that every dirty plate or bowl, had been covered in mold. Later as Alexander was cleaning he noticed something on one of of the bowls, it had the culture of “ staphylococci “ the culture had a tuft of yellow/green mold on it. When Fleming looked into the bowl he saw a ring around the mold. Later Fleming started to experiment on the cultures, he found that the around the mold was bacteria-free.He also found that the mold was really a rare spore called

Alexander Fleming did not discover Penicillin in a way, but Alexander Fleming was the first person to propose that the Penicillium mould must stash an antibacterial substance, and he was the first person to focus on the dynamic substance which he later named Penicillin in 1928 and for the next 12 years , he continued to grow and distributed the first mould , put was not the first person

Discovered completely by accident, Penicillin, one of the the world’s best and first anti killing bacteria saved thousands of lives during WWI and WWII thanks to its powerful ability to kill infectious bacteria. It was discovered by a British man named Dr.Fleming in England,1928.

Alexander Fleming has made contributions to advancement of biotechnology in several different ways. One major way was through his discovery of penicillin. Throughout life, we as humans will deal with many different types of bacterial infections. For instance, we may suffer from typhoid, cholera, tetanus caused by Pathogenic (Dougan, 1994). Some of us may
