How Do Natural Penicillins Work?

Penicillins are a group of antibiotics used to treat a wide range of bacterial infections (gram-positive and gram-negative). It was discovered in 1928 by Alexander Fleming (a professor of bacteriology) from a mold, the extract of which he named "penicillin." The discovery of penicillin has often been described as a miracle drug. They were among the first medications to be effective against many bacterial infections caused by staphylococci and streptococci.

Penicillins work by inhibiting bacterial cell wall synthesis (cell walls are necessary to protect the bacteria from their environment and keep the contents of the cell together) by attacking the peptidoglycans (a mesh-like structure that increases the strength of the cell wall) leading to the bursting of the bacteria and eventually its death.

Approximately 10% of people report an allergy to penicillins, whereas life-threatening reactions are extremely rare (0.03%). Skin testing for allergy may be performed to confirm if the person is allergic to penicillin.
