What it is

Vancomycin is a glycopeptide antibiotic originally derived from the soil bacterium Amycolatopsis orientalis. It works by binding to building blocks of the bacterial cell wall, blocking cell wall construction in Gram-positive bacteria. It is a prescription medicine sold under names including Vancocin and Vancomycin Hydrochloride.
