An antibiotic is an antimicrobial agent that inhibits or destroys the growth of bacteria. The first antibiotic in history was discovered by British biologist Alexander Fleming in 1928. He studied staphylococcus bacteria, for this he diluted them in Petri dishes. Once, after a month’s vacation, returning to the laboratory, he found that some of the staphylococcus cultures were infected with mold (this is not surprising, there was always a mess in the scientist’s laboratory), the bacteria in contact with the mold died. After careful study, the biologist found out that this mold is from the genus of fungi (penicilli), and has the unique ability to produce a substance that is harmful to a number of bacteria, which he called penicillin. The new discovery of the scientist was not immediately accepted, and only in 1942 the mass production of penicillin began (thanks to joint efforts with E. Cheyne and H. Flory). In 1945, all three received the Nobel Prize for their discovery.
