The Greatest Discovery in Biomedicine: Penicillin

Pathogenic bacteria are microorganisms that contribute to the development of bacterial diseases. In historical context, well-known infections cause epidemics such as plague, smallpox, cholera, typhoid, typhoid, etc. (Wassenaar, 2009). Special medicine called antibiotics is used to prevent or treat diseases. Antibiotics are chemical substances that kill, harm or inhibit the growth of pathogens. The selection of antibiotics by consumers begins with the discovery of penicillin, which plays an important role in medicine.

Penicillin is undoubtedly one of the greatest discoveries of human beings **. It must be the hero of our story. In 1907, syphilis could be treated from the death sentences of incurable diseases, but it turned into a terrible illness anyway. Finally late term syphilis finished in 1917. Suddenly there was hope. However, when penicillin appeared in 1943, the game really changed. For nearly a hundred years, the story of syphilis has become a holy grail of medical progress. Before the doctor seeks a small improvement, we are now looking for a big leap. Everyone wants to destroy all diseased silver bullets at once, not a slight increase. We are reviewing the advances of medicine in the 20th century - antibiotics, anesthesia, transplant surgery - and try to apply the same gauge to our brave new world.

The discovery of Scottish biologist Sir Alexander Fleming by his enzyme lysozyme (1921) and the antibiotic penicillin (1928) defined a new vision for modern antibiotics. Penicillin contained in Penicillium notatum improves the treatment of bacterial infections such as syphilis, gangrene and tuberculosis. He made a tremendous contribution to medicine through his work on bacteriology, immunology and chemotherapy. His research and his military career study stimulated him to discover natural antimicrobial enzymes in 1921 when he named lysozyme. This substance is contained in tissues and secretions such as mucus, tears, egg white, but it is not effective for strong harmful bacteria. Six years later, due to successful coincidence discovery, he stumbled on penicillin
