DefinitionPenicillin (sometimes abbreviated PCN) is a beta-lactam antibiotic used in the treatment of bacterial infections caused by susceptible, usually Gram-positive, organisms. It works by inhibiting the synthesis of the peptidoglycan layer of bacterial cell walls. The peptidoglycan layer is important for cell wall structural integrity, especially in Gram-positive organisms.
