Not to be confused with antibody. An antibiotic (or antibacterial) is something that kills bacteria or slows the growth of bacteria. They are used as medicines to cure diseases caused by bacteria. Antibiotics are no use against viruses. Penicillin, the first natural antibiotic, is produced by a fungus. Production started in 1939, and now it is made by chemical synthesis.
An antimicrobial is a type of drug that kills or stops the growth of microbes, such as bacteria, viruses, fungi, and parasites. Antibiotic resistance is the ability of bacteria to resist the effects of an antibiotic â that is, the bacteria are not killed, and their growth is not stopped.
