Definition

Etymology

The word is a combination of the Greek 'mikros' meaning 'small' and the Greek 'bios' meaning 'life,' combined with the suffix '-ome' used to denote a collective system. It emerged in the 20th century to describe the complex ecological community of microbes in a host or habitat.
