Jstor: how penicillin kills bacteria: progress and problems

Ne of the most important medical experiments in history. The work was so urgent that they came in to begin the experiment on the weekend, and on Saturday 25 May, Florey's team tested penicillin on eight mice injected with a lethal dose of streptococci bacteria. Four of the mice were treated with penicillin, while four were used as controls. By the next day, the treated mice had recovered and the untreated mice were dead. In the early days of World War II, the lives of eight mice may seem insignificant. But their rescue by penicillin led to the treatment of Allied soldiers as early as D-Day, in June 1944, and probably influenced the outcome of the war. The First Patient The results were so exciting Florey knew that it was time to test the drug on humans. The first patient in 1941 had been scratched by a rose thorn. Albert Alexander's whole face, eyes and scalp had swollen. He had already had an eye removed and abscesses drained; even his remaining eye had to be lanced to relieve the pai how penicillin

how penicillin is made Sformed penicillin from an interesting observation into a life saver. Emma Burkervisc used to be the tea lady at the Australian National University's John Curtin School of Medical Research (Howard Florey played a crucial role in the establishment of the School and University later in his life). Emma's life was saved by penicillin in a German refugee camp after World War II. Imagine how she felt many years later how penicillin is made, bumping into Florey in the corridors where she worked - the man who made the supply of penicillin possible. Imagine how you'd feel if you met someone who saved your life; and think of Florey and his team's impact on the world. Breaking the Mould Flor how penicillin is made.

how penicillin is made
Ome pink medicine that tasted like fruit? That was probably penicillin . Alexander Fleming discovered penicillin by accident 70 years ago and Howard Florey and his team made it into a life saving medicine over 55 years ago. Penicillin was the first antibiotic. It killed harmful bacteria that caused infections. Before penicillin, people died from simple infections. Now they can be cured in a matter of days. Types of Penicillin Penicillin is available in liquid, capsules, tablets and injections. The liquid penicillin is flavoured to taste like fruit so young children will enjoy taking their medicine. Any medicine with "cillin" at the end of its name is a type of penicillin. Synthetic penicillin is also known as Ampicillin, Oxacillin, Cloxacillin and Dicloxacillin. Use of Penicillin Today Even though now there are also many other antibiotics available, penicillin is still given to patients to fight certain bacterial infections. If you have a viral infection, penicillin or other antibiotics do not work. They kill bacteria not viruses. However, sometimes viral diseases are accompanied by bacterial infections. For example, people with the 'flu' can develop pneumonia caused by bacteria. The virus infection weakens the body's defences, so that bacterial infections can easily start. When this happens, antibiotics are of value. Production Today Even though there has been an enormous amount of research into antibiotics in the last 50 years, penicillin is still produced in much the same way as it was in 1943. Penicillin is not made from the same mould that Howard Florey used
