How has the world changed since penicillin was discovered?

Since then, the discovery of penicillin changed the course of medicine and has enabled physicians to treat formerly severe and life-threatening illnesses such as bacterial endocarditis, meningitis, pneumococcal pneumonia, gonorrhea and syphilis.

Who improved penicillin?

In 1928, at St. Mary’s Hospital, London, Alexander Fleming discovered penicillin. This discovery led to the introduction of antibiotics that greatly reduced the number of deaths from infection.

What did penicillin cause?

The discovery of penicillin changed the world of medicine enormously. With its development, infections that were previously severe and often fatal, like bacterial endocarditis, bacterial meningitis and pneumococcal pneumonia, could be easily treated.

What is the importance of penicillin?

Penicillin prevents the bacteria from synthesizing peptidoglycan, a molecule in the cell wall that provides the wall with the strength it needs to survive in the human body. The drug greatly weakens the cell wall and causes bacteria to die, allowing a person to recover from a bacterial infection.

Does penicillin treat gonorrhea?

Penicillin will cure most cases of gonorrhea, but cure is not necessarily accomplished by the first course of the drug or by penicillin alone.
