noun (plural eubacteria /-ˈti(ə)rēə/)
1A bacterium of a large group typically having simple cells with rigid cell walls and often flagella for movement. The group comprises the “true” bacteria and cyanobacteria, as distinct from archaebacteria.
- Kingdom Eubacteria; this group is sometimes taken to exclude nonrigid forms such as spirochetes and mycoplasmas.
- All protein sequences from 21 complete chloroplast genomes are analyzed in comparison with selected archaea, eubacteria, and eukaryotes.
- Initial sequence annotation has revealed an unusually high number of genes with no obvious similarity to previously described genes from eubacteria and archaea.
- What's more, these origin-of-life researchers suspect that the two major groups of bacteria, known as archaebacteria and eubacteria, originated on two separate occasions about 3.8 billion years ago.
2A bacterium found mainly in the intestines of vertebrates and in the soil.
- Genus Eubacterium; Gram-positive, anaerobic, rod-shaped bacteria.
- Malignancy or another process in the colon can induce sepsis with Clostridium species (especially Clostridium septicum) or arthritis caused by Eubacterium lentum, or it can emerge first as abdominal wall myonecrosis.
- Chlamydiae are Gram-negative eubacteria that replicate strictly inside eukaryotic cells.
- Example sentences
- The eukaryotic nuclear genes are more similar to eubacterial than to archaebacterial homologs.
- In it he stated the principle of ‘irreducible complexity’ and claimed that, amongst other things, the clotting system and the eubacterial flagella were irreducibly complex, and were not evolvable.
- For the purposes of this blog though, it is enough to point out that while Dembski and Behe characterize the eubacterial flagella, a swimming motility system, as an ‘outboard motor’, it is also a secretory system.
