Nota de escopo: Uno de los tres dominios de la VIDA (los otros son Eukarya y ARCHAEA), también llamado EUBACTERIA. Son microorganismos procariotas unicelulares que generalmente poseen paredes celulares rígidas, se multiplican por DIVISIÓN CELULAR y exhiben tres formas principales: redondeada o de coco, en forma de bastón o bacilar y espiral o espiroquetal. Las bacterias se pueden clasificar por su respuesta al OXÍGENO: aerobias, anaerobias o anaerobias facultativas; por el modo en que obtienen su ENERGÍA: quimiotrofía (por una reacción química) o fototrofía (por una reacción luminosa); las quimiótrofas [o quimiotróficas], por su fuente de ENERGÍA química: litótrofas [o litotróficas] (a partir de COMPUESTOS INORGÁNICOS) u organótrofas [u organotróficas] (a partir de COMPUESTOS ORGÁNICOS); y por su fuente de CARBONO: heterótrofas [o heterotróficas] (a partir de fuentes orgánicas) o autótrofas [o autotróficas] (a partir del DIÓXIDO DE CARBONO). También se pueden clasificar dependiendo de si se tiñen o no (propiedad basada en la estructura de la PARED CELULAR) con VIOLETA DE GENCIANA: gramnegativas y grampositivas.

Nota de escopo: 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.
Nota de indexação: general; prefer specifics; relation to bacterial disease: Manual 22.12-22.16; presence of bacteria in organs vs infection: Manual 22.11; note many precoordinated bacterial - terms (BACTERIAL PROTEINS; ANTIBODIES, BACTERIAL; etc); "coliform bacteria" = COLIFORM BACILLI see ENTEROBACTERIACEAE; presence of bacteria in blood = BACTEREMIA: see note there
