If you wonder why so many people think antibiotics can treat colds and flu (viruses), perhaps its because sick people are using search engines to figure out what antibiotics are. Below are some examples of what people will find. I’ve included definitions of “microorganism” because so many definitions of “antibiotic” contain that term.
antibiotic: a medicine (such as penicillin or its derivatives) that inhibits the growth of or destroys microorganisms.
microorganism: a microscopic organism, especially a bacterium, virus, or fungus.
antibiotic: any of a large group of chemical substances, as penicillin or streptomycin, produced by various microorganisms and fungi, having the capacity in dilute solutions to inhibit the growth of or to destroy bacteria and other microorganisms, used chiefly in the treatment of infectious diseases.
microorganism: any organism too small to be viewed by the unaided eye, as bacteria,protozoa, and some fungi and algae.
antibiotic: a substance produced by or a semisynthetic substance derived from a microorganism and able in dilute solution to inhibit or kill another microorganism.
microorganism: an extremely small living thing that can only be seen with a microscope.
antibiotic: A substance, such as penicillin or erythromycin, produced by or derived from certain microorganisms, including fungi and bacteria, that can destroy or inhibit the growth of other microorganisms, especially bacteria. Antibiotics are widely used in the prevention and treatment of infectious diseases.
microorganism: any organism, such as a bacterium, protozoan, or virus, of microscopic size.
antibiotic: chemical substance produced by a living organism, generally a microorganism, that is detrimental to other microorganisms. Antibiotics commonly are produced by soil microorganisms and probably represent a means by which organisms in a complex environment, such as soil, control the growth of competing microorganisms.
microorganisms: living things that are too small to be seen with the naked eye. They are normally viewed using a microscope. Bacteria, viruses, and some molds are examples of microorganisms.
antibiotic: Any substance that can destroy or inhibit the growth of bacteria and similar microorganisms.
microorganism: An organism that is too small to be seen by the unaided eye, especially a single-celled organism, such as a bacterium.
