Penicillin is a widely used antibiotic prescribed to treat staphylococci and streptococci bacterial infections. Penicillin belongs to the beta-lactam family of antibiotics, the members of which use a similar mechanism of action to inhibit bacterial cell growth that eventually kills the bacteria. Bacteria cells are surrounded by a protective envelope called the cell wall.
Penicillins What are Penicillins. Penicillins are a type of antibiotic derived from Penicillium fungi. Alexander Fleming discovered the first penicillin in 1928 (benzylpenicillin also called penicillin G). Since then, several other penicillins have been derived, and the original structure has been modified to create new penicillins with enhanced effectiveness against a broader range of bacteria.
