“Bacteria kingdom (Bacterium)”  

Kingdom Bacterium

  In nature, Bacteria, aka Eubacteria, a kingdom in the Prokaryota empire system and the Monera system, are a major diverse group of single-cell, prokaryotic microorganisms (prokaryotes) that lack a true nucleus and organelles.
  

Examples of subsets and other related entities of bacterium taxonomy include:
Acidobacteria phylum Aquificae phylum Caldiserica/Cryosericota group includes: Caldiserica phylum Candidatus Cryosericota phylum Calditrichaeota phylum Chrysiogenetes phylum Coprothermobacterota phylum Deferribacteres phylum Dictyoglomi phylum Elusimicrobia phylum FCB group Fibrobacteres phylum Gemmatimonadetes phylum Bacteroidetes/Chlorobi group Bacteroidetes phylum Balneolaeota phylum Chlorobi phylum Ignavibacteriae phylum Rhodothermaeota phylum Candidatus Kapabacteria phylum Candidatus Aegiribacteria genus Candidatus Cloacimonetes phylum Candidatus Fermentibacteria phylum Candidatus Hydrogenedentes phylum Candidatus Kryptonia phylum Candidatus Latescibacteria phylum Candidatus Marinimicrobia phylum candidate division Zixibacteria phylum	Fusobacteria phylum Nitrospinae/Tectomicrobia group Candidatus Tectomicrobia phylum Nitrospinae phylum Nitrospirae phylum Proteobacteria phylum PVC group Chlamydiae phylum Kiritimatiellaeota phylum Lentisphaerae phylum Planctomycetes phylum Verrucomicrobia phylum Candidatus Abyssubacteria phylum Candidatus Aureabacteria phylum Candidatus Omnitrophica phylum Spirochaetae phylum Synergistetes phylum Terrabacteria group Abditibacteriota phylum Actinobacteria phylum Armatimonadetes phylum Chloroflexi phylum Deinococcus-Thermus phylum Firmicutes phylum Tenericutes phylum Thermodesulfobacteria Thermotogae Bacteria incertae sedisÂÂ

“Bacteria domain (Eubacteria)”  

Bacteria

  In the three domain system, Bacteria, formerly called Eubacteria, is a large domain of unicellular prokaryotic microorganisms, and one of the three domains of life, the others being Archaea (Archaebacteria) and Eukaryota (Eukarya).
  The cells in the Bacteria differ from all other organisms (the eukaryotes), because bacteria lack a true nucleus and organelles such as mitochondria, chloroplasts and lysosomes. A bacterium refers to a single bacteria cell (singular for Bacteria).

Examples of topics, concepts, subjects and other related entities of Bacteria include:

• Bacteria kingdom (superkingdom)
• blood-borne bacteria pathogens (pathogenic bacteria)
• endospore-forming bacteria
• nitrogen-fixing bacteria
• sulfur-reducing bacteria

Each bacterium of the Bacteria domain may be classified in various ways based on different characteristics and metabolic properties.
  Bacteria generally possess a rigid cell wall, multiplies by cell division, and exhibits three principal forms:

• round or coccal
• rodlike or bacillary
• spiral or spirochetal

Examples of the common classification criteria for bacteria include:
principal forms oxygen preference of bacteria Mode of Obtaining Energy	Source of Chemical Energy (for chemotrophs) Source of Carbon, Nitrogen Gram-stained reactions
