Eickhoff, MD The discovery of penicillin changed the world of medicine enormously. With its development, infections that were previously severe and often fatal, like bacterial endocarditis, bacterial meningitis and pneumococcal pneumonia, could be easily treated.
Even dating all the way back to World War II and today with the war in Iraq, soldiers experienced injuries that would have been fatal without penicillin and other antibiotics that were developed subsequently.
Soil samples were sent in from around the world. But the solution was found closer to home. US Pharmaceutical companies were initially reluctant to commit to large scale penicillin production.
But bacteria have evolved to become resistant to the original penicillin and many other antibiotics. Scientists are now in a race to find and develop new antibiotics. As bacteria become increasingly resistant to the antibiotics we have relied on for decades, how are scientists developing new treatments to fight the infections of today? While the search for new antibiotic drugs continues, scientists and medics are taking inspiration from past treatments and approaches to limit infection.
Antibiotics were nothing short of miraculous when they were first mass produced in s. In , Fleming discovered lysozyme, an enzyme with weak antibacterial properties that inhibited bacterial growth. He also found lysozyme in fingernails, hair, saliva, skin, and tears. In his research, Fleming found that lysozyme was effective against only a small number of non-harmful bacteria.
In , he started to research common staphylococcal bacteria. An uncovered Petri dish near an open window became contaminated with mold.
Fleming realized that the bacteria near the mold were dying. He isolated the mold and identified it as Penicillium genus, which he found to be effective against all Gram-positive pathogens.
Gram-positive pathogens cause diseases, such as diphtheria, gonorrhea, meningitis, pneumonia, and scarlet fever. But I suppose that was exactly what I did. Soon, they were able to mass produce penicillin for use during World War II.
He was also named one of the most important people of the 20th century by Time Magazine. In terms of his personal life, Fleming was known as modest, patient, quiet, shy, and unemotional.
