LactobacillaceaeA family of gram-positive bacteria found regularly in the mouth and intestinal tract of man and other animals, in food and dairy products, and in fermenting vegetable juices. A few species are highly pathogenic.
FamilyA social group consisting of parents or parent substitutes and children.
BacteriaOne 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: chemotrophic (via chemical reaction) or phototrophic (via light reaction); for chemotrophs by their source of chemical energy: lithotrophic (from inorganic compounds) or organotrophic (from organic compounds); and by where they get their CARBON: heterotrophic (from organic sources) or autotrophic (from CARBON DIOXIDE). They can also be classifed by whether or not they stain (based on the structure of their CELL WALLS) with CRYSTAL VIOLET dye: gram-negative or gram-positive.
MouthThe oval-shaped oral cavity located at the apex of the digestive tract and consisting of two parts: the vestibule and the oral cavity proper.
Part of the oral cavity bounded laterally and ventrally by the alveolar arches and their contained TEETH. Its roof is formed by the PALATE and it communicates posteriorly with the OROPHARYNX.
Slitlike space in the ORAL CAVITY, bounded externally by the LIPS and CHEEK, and internally by the GINGIVA and TEETH.
FoodAnything which, when taken into the body, serves to nourish or build up the tissues or to supply body heat. (Dorland, 27th ed)
