Classification seeks to describe the diversity of bacterial species by naming and grouping organisms based on similarities. In the scientific classification established by Carl Linnaeus, each species has to be assigned to a genus (binary nomenclature), which in turn is a lower level of a hierarchy of ranks (family, suborder, order, subclass, class, division/phyla, kingdom and domain).
