Antibiotics are compounds used to treat or prevent bacterial infections by killing or inhibiting growth of bacteria. They are also used in cell culture to prevent contamination, particularly by Mycoplasma species. Antibiotics may be chemically synthesized or isolated from natural sources, such as fungi.
