Mary’s Hospital in London. Fleming grew a pure culture of the mold and discovered it to be an antibacterial agent that would eventually become penicillin, the most widely used antibiotic class to date.

Topical iodine, bromine and mercury-containing compounds were used to treat infected wounds and gangrene during the American Civil War. Bromine was used most frequently, but was very painful when applied topically or injected into a wound, and could cause tissue damage itself.
What does penicillin do to the body?
How do penicillin antibiotics work? Penicillin antibiotics stop bacteria from multiplying by preventing bacteria from forming the walls that surround them. The walls are necessary to protect the bacteria from their environment, and to keep the contents of the bacterial cell together.
