true bacteria

Noun
  1. A large group of bacteria having rigid cell walls;
    Motile types have flagella (synset 101357967)
    is a type of:
    • moneran, moneron - organisms that typically reproduce by asexual budding or fission and whose nutritional mode is absorption or photosynthesis or chemosynthesis
    • bacteria, bacterium - (microbiology) single-celled or noncellular spherical or spiral or rod-shaped organisms lacking chlorophyll that reproduce by fission; important as pathogens and for biochemical properties; taxonomy is difficult; often considered to be plants
    subtypes:
    • b, bacillus - aerobic rod-shaped spore-producing bacterium; often occurring in chainlike formations; found primarily in soil
    • cocci, coccus - any spherical or nearly spherical bacteria
    • coccobacillus - a bacterial cell intermediate in morphology between a coccus and a bacillus; a very short bacillus
    • spirilla, spirillum - any flagellated aerobic bacteria having a spirally twisted rodlike form
    • clostridia, clostridium - spindle-shaped bacterial cell especially one swollen at the center by an endospore
    • botulinum, botulinus, clostridium botulinum - anaerobic bacterium producing botulin the toxin that causes botulism
    • clostridium perfringens - anaerobic Gram-positive rod bacterium that produces epsilon toxin; can be used as a bioweapon
    • blue-green algae, cyanobacteria - predominantly photosynthetic prokaryotic organisms containing a blue pigment in addition to chlorophyll; occur singly or in colonies in diverse habitats; important as phytoplankton
    • phototrophic bacteria, phototropic bacteria - green and purple bacteria; energy for growth is derived from sunlight; carbon is derived from carbon dioxide or organic carbon
    • pseudomonad - bacteria usually producing greenish fluorescent water-soluble pigment; some pathogenic for plants and animals
    • xanthomonad - bacteria producing yellow non-water-soluble pigments; some pathogenic for plants
    • nitric bacteria, nitrobacteria - soil bacteria that convert nitrites to nitrates
    • nitrosobacteria, nitrous bacteria - soil bacteria that oxidize ammonia to nitrites
    • thiobacillus - small rod-shaped bacteria living in sewage or soil and oxidizing sulfur
    • spirillum - spirally twisted elongate rodlike bacteria usually living in stagnant water
    • vibrio, vibrion - curved rodlike motile bacterium
    • corynebacterium - any species of the genus Corynebacterium
    • listeria - any species of the genus Listeria
    • enteric bacteria, enterics, enterobacteria, entric - rod-shaped Gram-negative bacteria; most occur normally or pathogenically in intestines of humans and other animals
    • endospore-forming bacteria - a group of true bacteria
    • rickettsia - any of a group of very small rod-shaped bacteria that live in biting arthropods (as ticks and mites) and cause disease in vertebrate hosts; they cause typhus and other febrile diseases in human beings
    • chlamydia - coccoid rickettsia infesting birds and mammals; cause infections of eyes and lungs and genitourinary tract
    • mycoplasma - any of a group of small parasitic bacteria that lack cell walls and can survive without oxygen; can cause pneumonia and urinary tract infection
    • actinomycete - any bacteria (some of which are pathogenic for humans and animals) belonging to the order Actinomycetales
    • actinomyces - soil-inhabiting saprophytes and disease-producing plant and animal parasites
    • mycobacteria, mycobacterium - rod-shaped bacteria some saprophytic or causing diseases
    • gliding bacteria, myxobacter, myxobacteria, myxobacterium, slime bacteria - bacteria that form colonies in self-produced slime; inhabit moist soils or decaying plant matter or animal waste
    • lactobacillus - a Gram-positive rod-shaped bacterium that produces lactic acid (especially in milk)
    • strep, streptococci, streptococcus - spherical Gram-positive bacteria occurring in pairs or chains; cause e.g. scarlet fever and tonsillitis
    • spirochaete, spirochete - parasitic or free-living bacteria; many pathogenic to humans and other animals
    belongs to: division eubacteria - one-celled monerans having simple cells with rigid walls and (in motile types) flagella
    has: flagellum - a lash-like appendage used for locomotion (e.g., in sperm cells and some bacteria and protozoa)
    same as: eubacteria, eubacterium
