kingdom Monera, Monera - prokaryotic bacteria and blue-green algae and various primitive pathogens; because of lack of consensus on how to divide the organisms into phyla informal names are used for the major divisions

bacteria order - an order of bacteria

bacteria family - a family of bacteria

bacteria genus - a genus of bacteria

bacteria species - a species of bacteria

eubacteria, eubacterium, true bacteria - a large group of bacteria having rigid cell walls; motile types have flagella

Eubacteriales, order Eubacteriales - one of two usually recognized orders of true bacteria; gram-positive spherical or rod-shaped forms; some are motile; in some classifications considered an order of Schizomycetes

Cyanophyta, division Cyanophyta - prokaryotic organisms sometimes considered a class or phylum or subkingdom; coextensive with the Cyanophyceae: cyanobacteria (blue-green algae)

division Schizophyta, Schizophyta - former term for the Cyanophyta

order Pseudomonadales, Pseudomonadales - one of two usually recognized orders of true bacteria; gram-negative spiral or spherical or rod-shaped bacteria usually motile by polar flagella; some contain photosynthetic pigments

order Rickettsiales, Rickettsiales - pleomorphic gram-negative microorganisms

Mycoplasmatales, order Mycoplasmatales - coextensive with the family Mycoplasmataceae

Actinomycetales, order Actinomycetales - filamentous or rod-shaped bacteria

Myxobacterales, Myxobacteriales, order Myxobacterales, order Myxobacteria, order Myxobacteriales - an order of higher bacteria

family Micrococcaceae, Micrococcaceae - spherical or elliptical usually aerobic eubacteria that produce yellow or orange or red pigment; includes toxin-producing forms as well as harmless commensals and saprophytes

order Spirochaetales, Spirochaetales - higher bacteria; slender spiral rodlike forms

division - (biology) a group of organisms forming a subdivision of a larger category
