What is Elie metchnikoff known for?
Metchnikoff is rightly famous for his recognition of the biological significance of leukocyte recruitment and phagocytosis of microbes in host defence against infection, inflammation and immunity. As a comparative zoologist he utilised a broad range of model organisms for microscopic studies in vivo and in vitro.

When was natural immunity discovered?
In the 10th century, Persian physician al-Razi (also known as Rhazes) wrote the first recorded theory of acquired immunity, noting that a smallpox bout protected its survivors from future infections.
Who got Nobel Prize for phagocytic activity?
Ilya Mechnikov contributed in several ways to our understanding of how this happens. After studies of starfish larvae, in 1882 he pointed to phagocytosis as one of the immune system’s ways of operating.
Who invented prebiotics?
Probiotics, as we know them, began their journey over a century ago when they were discovered by Russian scientist and Nobel Prize winner, Elie Metchnikoff of the Pasteur Institute in Paris.
Why is it called probiotic?
The term probiotic is derived from the Latin preposition “pro,” which means “for” and the Greek word “biotic” meaning “bios” or “life”. The concept that the gut flora can be modified and harmful microbes replaced with beneficial ones was first introduced in 1907 by a Russian scientist called Elie Metchnikoff.
