Noun1.true bacteria - a large group of bacteria having rigid cell walls; motile types have flagella
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
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
division Eubacteria - one-celled monerans having simple cells with rigid walls and (in motile types) flagella
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
flagellum - a lash-like appendage used for locomotion (e.g., in sperm cells and some bacteria and protozoa)
