Antibiotics are one of the most important discoveries in the history of medicine. They allow you to fight infectious diseases that were fatal in the past. But who invented antibiotics?
The history of antibiotics begins in 1928. This year, the British bacteriologist Alexander Fleming noticed that a mold had appeared on a Petri disk on which a culture of staphylococcus bacteria had been grown. Fleming found that the bacteria did not grow around the mold, but instead died.
This case became the starting point for further research. Fleming and his colleagues studied the properties of the mold and found that it contains a substance that has an antimicrobial effect on bacteria. This substance was named penicillin.
However, the first experiments with penicillin were not very successful. The substance was unstable and could not retain its properties for a long time. In addition, it was not possible to produce penicillin in large quantities.
The situation changed in the 1940s, when a scientific team led by Ernst Cheyne from Switzerland developed a method for the production of penicillin on an industrial scale. Since then, antibiotics have become widely used in medicine.
Since then, many different antibiotics have been discovered, each of which affects certain types of bacteria. Some antibiotics are still widely used today, such as penicillin and tetracycline.
However, it must be understood that due to the misuse of antibiotics, bacteria can develop resistance to them. Therefore, it is very important to use antibiotics only when prescribed by a doctor and follow the instructions for their use.
As a result, the invention of antibiotics is one of the most significant achievements in medicine. Thanks to this discovery, millions of people around the world can receive effective treatment for infectious diseases.
