Related to Eubacteria: archaebacteria
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.
