An antibiotic (or antibacterial) is a chemical compound that kills bacteria or slows their growth. They are used as medicine to treat and cure diseases caused by bacteria. The first antibiotic discovered was Penicillin, a natural antibiotic produced by a fungus.
A broad-spectrum antibiotic is an antibiotic that acts on the two major bacterial groups, Gram-positive and Gram-negative, or any antibiotic that acts against a wide range of disease-causing bacteria.
