Elaborating the possibility of penicillin resistance in clinical conditions in his Nobel Lecture, Fleming said: The time may come when penicillin can be bought by anyone in the shops. Then there is the danger that the ignorant man may easily underdose himself and by exposing his microbes to non-lethal quantities of the drug make them resistant ...
Most of the antibiotics used today come from microbes, or microscopic organisms. They are produced in nature and over two-thirds of antibiotics, such as penicillin, come from soil bacteria and fungi.
