Bacteria. Eubacteria . Gliding Bacteria . Schizomycetes . Spiral and Curved Bacteria . Phototrophic Bacteria . Budding and Appendaged Bacteria . One of the three domains of life (the others being Eukarya and ARCHAEA), also called Eubacteria. They are unicellular prokaryotic microorganisms which generally possess rigid cell walls, multiply by cell division, and exhibit three principal forms: round or coccal, rodlike or bacillary, and spiral or spirochetal. Bacteria can be classified by their response to OXYGEN: aerobic, anaerobic, or facultatively anaerobic; by the mode by which they obtain their energy: chemotrophy (via chemical reaction) or PHOTOTROPHY (via light reaction); for chemotrophs by their source of chemical energy: CHEMOLITHOTROPHY (from inorganic compounds) or chemoorganotrophy (from organic compounds); and by their source for CARBON; NITROGEN; etc.; HETEROTROPHY (from organic sources) or AUTOTROPHY (from CARBON DIOXIDE). They can also be classified by whether or not they stain (based on the structure of their CELL WALLS) with CRYSTAL VIOLET dye: gram-negative or gram-positive. . 0.64
Eubacterium. Butyribacterium . A genus of gram-positive, rod-shaped bacteria found in cavities of man and animals, animal and plant products, infections of soft tissue, and soil. Some species may be pathogenic. No endospores are produced. The genus Eubacterium should not be confused with EUBACTERIA, one of the three domains of life. . 0.61
Balaenoptera. Balaenoptera borealis . Balaenoptera brydei . Balaenoptera musculus . Blue Whales . Bryde Whale . Brydes Whale . Sei Whales . Blue Whale . Bryde's Whale . Sei Whale . Rudolphi's Rorqual . Pollack Whale . Coalfish Whale . A genus of WHALES in the family Balaenopteridae, consisting of five species: Blue Whale, Bryde's Whale, FIN WHALE, Sei Whale, and MINKE WHALE. They are distinguished by a relatively slender body, a compressed tail stock, and a pointed snout. . 0.35
Bowhead Whale. Balaena mysticetus . Greenland, Right Whale . Bowhead Whales . Greenland Right Whale . Greenland Right Whales . Right Whale Greenland . Right Whales, Greenland . Whales, Greenland Right . Right Whale, Greenland . Right Whale . Right Whales . The species Balaena mysticetus, in the family Balaenidae, found in the colder waters of the Northern Hemisphere. The common name is derived from the extreme arching of the lower jaw. . 0.32
