Returning to Odessa, Mechnikov visited Vienna on the way and explained his ideas to Claus, Professor of Zoology there and it was Claus who suggested the term phagocyte for the mobile cells which act in this way.
Cellular assays include immunophenotyping of specific cell populations as well as assays for lymphocyte and phagocyte function.
When pathogenic microbes were discovered in the 1870s, Metchnikoff soon applied to the phagocyte the new role of defending the organism against invaders.
Indeed, on this view, the phagocyte became an exemplar combatant of Darwinian struggle, now occurring within the organism.
He found such an agent in the phagocyte, which retained its ancient phylogenetic eating function, to devour effete, dead, or injured cells that violated the phagocyte's sense of organismal identity.

One type of phagocyte—a macrophage—is known as “big-eater.”
