We found 2 definitions of eubacteria from 2 different sources.
NounPlural: eubacterias |
||
eubacteria - a large group of bacteria having rigid cell walls; motile types have flagella | ||
eubacterium, true bacteria | ||
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 | ||
moneran, moneron organisms that typically reproduce by asexual budding or fission and whose nutritional mode is absorption or photosynthesis or chemosynthesis | ||
division eubacteria one-celled monerans having simple cells with rigid walls and (in motile types) flagella | ||
bacillus, b 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 any flagellated aerobic bacteria having a spirally twisted rodlike form | ||
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 |
