The word microorganism comes from the Greek, formed by "mikro" which means small, plus the root "organon" which means organ, tool or instrument, and the suffix "ism" which means activity or system. A microorganism is understood to be all those organisms, forms of life or unicellular living beings , for the most part, although in some cases they are cenotic organisms composed of very small multinucleated cells, or even multicellular, that can only be divided by means of a microscope; The science that studies these microscopic phenomena is microbiology. These microorganisms include bacteria, viruses, molds, and yeasts.
These microorganisms, also called microbes, it is worth noting; They can cause damage or deterioration of many foods, and thus cause diseases when consumed due to their contamination, these are pathogenic microorganisms, which, if they are not fought in time, the infected person, animal or plant can suffer diseases that can generate complications, thus putting your life at risk or also infect people who have contact with them. Although some pathogenic microorganisms that do not cause such deterioration in food can be found, and therefore it is important to add that there are some microorganisms that are usually of benefit and benefit, until they are used in food processing in order to extend their durability or to change their properties; a common case of this is the fermentation that is carried out for the production of cheeses or yogurt. And finally we can say that microbes have different sizes and shapes.
