Is penicillin an accidental invention?

The accidental discovery of a mouldy petri-dish in 1928 kickstarted a 20-year long journey to develop the world’s first mass produced drug that could clear a bacterial infection; penicillin.

How did Fleming accidentally discovered penicillin?

Upon examining some colonies of Staphylococcus aureus, Dr. Fleming noted that a mold called Penicillium notatum had contaminated his Petri dishes. After carefully placing the dishes under his microscope, he was amazed to find that the mold prevented the normal growth of the staphylococci.

What happens if you take antibiotics incorrectly?

Taking antibiotics too often or for the wrong reasons can change bacteria so much that antibiotics don’t work against them. This is called bacterial resistance or antibiotic resistance. Some bacteria are now resistant to even the most powerful antibiotics available. Antibiotic resistance is a growing problem.

Yet Fleming himself was unconvinced penicillin could be turned into an effective treatment and lost interest in his discovery.

In the generally accepted account, Fleming noticed that there were no bacteria growing close to a mould that had accidentally been introduced to the culture.
