Eubacteria (ū″băk-tēr′ē-ă) A group of single-celled organisms without a defined cell nucleus or organelles. They contain peptidoglycans in their cell walls. Eubacteria are prokaryotes and include many familiar microorganisms, (e.g., Escherichia, Helicobacter, Legionella, nitrogen-fixing bacteria, Spirochetes, and staphylococci.) In some classification systems the other prokaryotes also include the archaebacteria and cyanobacteria. In other taxonomic systems the archaebacteria are considered to be a separate kingdom or domain. Eubacteria one of the three primary groupings (DOMAINS) according to some classifications, based on genetic structures and sequences, though it is more commonly called the BACTERIA. In other classifications it is the name for the ‘true’ bacteria.eubacteria
