Probiotics are live bacteria that may confer a health benefit on the host.
In the past, there were other definitions of probiotics. The first use of the word “Probiotic” as microorganisms that have effects on other microorganism was accredited to Lilly and Stilwell (1965), expressed as follows: Substances secreted by one microorganism that stimulate another microorganism.
Again, the term was used in 1971 by Sperti to describe tissue extracts which stimulated microbial growth. The word was later described by Parker in 1974 who advanced the meaning of the term by adding the word organisms to the definition, thereby describing probiotics as “Organisms and substances that have a beneficial effect on the host animal by contributing to its intestinal microbial balance”.
Later, the definition was greatly improved by Fuller in 1989, whose explanation was very close to the definition used today. Fuller in 1989 described probiotics as “live microbial feed supplement which beneficially affects the host animal by improving its intestinal microbial balance”.
He stressed two important facts of probiotics: the viable nature of probiotics and the capacity to help with intestinal balance. Alternative expert review indicates there is insufficient scientific evidence for supplemental probiotics having a benefit.
Lactic acid bacteria (LAB) and bifidobacteria are the most common types of microbes used as probiotics, but certain yeasts and bacilli may also be used.
Probiotics are commonly consumed as part of fermented foods with specially added active live cultures, such as in yogurt, soy yogurt, or as dietary supplements.
Probiotics are also delivered in fecal transplants, in which stool from a healthy donor is delivered like a suppository to an infected patient.
