During WWII, penicillin cured or dramatically reduced deaths from bacterial infections, saving countless soldiers from dying of infected wounds, pneumonia, gangrene, blood poisoning (septicemia), meningitis, and other serious bacterial illnesses that were previously often fatal. It transformed military medicine, turning life-threatening injuries into treatable conditions, significantly lowering mortality rates from infections.
It is estimated that penicillin reduced the mortality rate from bacterial infections among wounded soldiers by 15%. This life-saving drug also prevented amputations and sped up recovery times, allowing soldiers to return to duty more quickly.
By 1941, there was an injectable form that could be used to treat patients, which was especially useful for soldiers fighting in World War II. Today, penicillin, considered the first wonder drug, is used to treat throat infections, meningitis, syphilis and other bacterial infections.
It is perhaps too much to suggest that penicillin helped win World War II. But it must have felt that way, at least on a personal level, to the 100,000 or so men, by one conservative estimate, who benefited from penicillin treatment in the European Theater between D-Day and the final German surrender.
During the Second World War, the Germans and their Axis partners could only produce relatively small amounts of penicillin, certainly never enough to meet their military needs; as a result, they had to rely upon the far less effective sulfonamides.
Penicillin Production in the United States during WWII
With the support of the Rockefeller Foundation, Florey and his colleague Norman Heatley traveled to the United States in the summer of 1941 to see if they could interest the American pharmaceutical industry in the effort to produce penicillin on a large scale.
The simple discovery and use of the antibiotic agent has saved millions of lives, and earned Fleming – together with Howard Florey and Ernst Chain, who devised methods for the large-scale isolation and production of penicillin – the 1945 Nobel Prize in Physiology/Medicine.
Penicillin kills by preventing some bacteria from forming new cell walls. One by one, the bacteria die because they cannot complete the process of division that produces two new "daughter" bacteria from a single "parent" bacterium. The new cell wall that needs to be made to separate the "daughters" is never formed.
In just over 100 years antibiotics have drastically changed modern medicine and extended the average human lifespan by 23 years. The discovery of penicillin in 1928 started the golden age of natural product antibiotic discovery that peaked in the mid-1950s.
After the end of the war in 1945, penicillin became widely available. Dorothy Hodgkin determined its chemical structure, one of the achievements for which she received the Nobel Prize in Chemistry in 1964.
Over time, bacteria have developed resistance to natural penicillins. This means that certain types of bacteria can prevent antibiotics from damaging their cells. This has happened many times since penicillin's first use.
Key takeaways: Penicillin and amoxicillin are antibiotics that treat a variety of bacterial infections, including strep throat. Penicillin is an older antibiotic, and it doesn't fight as many types of bacteria as amoxicillin. But they're both possible first-choice options for treating strep throat.
Penicillium mold naturally produces the antibiotic penicillin.
Penicillin truly looked like a miracle drug: infections that had been killing people previously were cured. As companies in the US and UK began to take up manufacture of penicillin, enough was being produced to treat some of the military.
Penicillin was used in the D-Day landings, dramatically reducing the death toll from infected wounds. Penicillin has since inspired researchers worldwide, leading to the discovery of new antibiotics to treat many of the infectious diseases that threaten humans and animals.
Since then, the discovery of penicillin changed the course of medicine and has enabled physicians to treat formerly severe and life-threatening illnesses such as bacterial endocarditis, meningitis, pneumococcal pneumonia, gonorrhea and syphilis.
Penicillin is estimated to be responsible for saving over 500 million lives since its discovery, becoming the first successful and scalable way to effectively treat a bacterial infection.
If you take too much
Taking an extra dose of phenoxymethylpenicillin is unlikely to harm you or your child. Taking more than 1 extra dose could make you feel sick and cause vomiting and diarrhoea. Rest and take it easy until these side effects get better. Speak to your pharmacist or doctor if you're worried.
The "90/60 rule" in antibiotics is a guideline stating that infections from bacteria deemed susceptible in lab tests succeed about 90% of the time with appropriate treatment, while infections from bacteria classified as resistant still respond successfully in about 60% of cases, bridging the gap between lab results (in vitro) and real-world outcomes (in vivo) by acknowledging factors like the immune system, drug penetration, and patient conditions.

Prontosil killed a type of bacteria known as streptococcal, which could cause life-threatening infections. The discovery of magic bullets by Ehrlich's research team also led to work on finding natural substances that could target infections in the body. This work led to the discovery and development of penicillin.
Penicillin which can cure a large number of diseases is called the queen of drugs because of its superiority to that of the other drugs in killing the antibodies.
Discovered in 1928 by Alexander Fleming, the drug was made medically useful in the 1940s by a team of Oxford scientists led by Australian Howard Florey and German refugee Ernst Chain. Penicillin has since saved countless lives. Howard Florey, 1967: The three of us got it together.
One person, Linus Pauling, has won two undivided Nobel Prizes. In 1954 he won the Prize for Chemistry. Eight years later he was awarded the Peace Prize for his opposition to weapons of mass destruction. The atom bombs dropped on Hiroshima and Nagasaki were a turning point in Pauling's life.
Fleming's legacy is carried on through establishments named after him. These include the Alexander Fleming Laboratory Museum at St. Mary's Hospital and other learning institutions. He and his work can inspire every scientist and doctor engaged in developing healthcare and the fight against infectious diseases.
