History and Development . Penicillin, derived from the Penicillium fungi, is a group of antibiotics that revolutionized medicine.Its discovery is credited to Scottish microbiologist Alexander Fleming, who observed in 1928 that a mold had contaminated his petri dish and eradicated the bacteria he had been studying, leading to the …
Mode of Action (MOA) of Penicillin Antibiotics
Penicillins, and other beta-lactam antibiotics, work by interfering with interpeptide linking of peptidoglycan, the a strong, structural molecule found specifically bacterial cell walls. Cell walls without intact peptidoglycan cross-links are structurally weak, prone to collapse and disintegrate when the bacteria attempts to divide.
