- (microbiology) single-celled or noncellular spherical or spiral or rod-shaped organisms lacking chlorophyll that reproduce by fission; crucial as pathogens and biochemical properties; taxonomy is difficult; usually considered to be flowers
- See Bacterium.
- of Bacterium
Single-celled microorganisms that will occur either as separate (free-living) organisms or as parasites (determined by another organism for a lifetime). The plural of bacterium. Types of germs include Acidophilus, a normal inhabitant of yogurt; Gonococcus which causes gonorrhea; Clostridium welchii, the most frequent reason for gangrene; E. coli, which life in the colon and can trigger disease somewhere else; and Streptococcus, the bacterium that triggers the typical throat illness known as strep neck.
cellular this is certainly microscopic. It really is single-cell and is present every-where. Just a fraction of them are recognized to science. They truly are divided in five groups bacilli, cocci, filamentous, spirilla/spirochetes, and vibrio. They can be safe or be harmful.
1847, plural of Modern Latin bacterium, from Greek bakterion "small staff," diminutive of baktron "stick, pole," from PIE *bak- "staff utilized for help" (in addition source of Latin baculum "rod, walking stick"). So-called because the very first ones seen had been rod-shaped. Introduced as a scientific word 1838 by German naturalist Christian Gottfried Ehrenberg (1795-1876).
Singular 'bacterium.' Microscopic single-cell (unicellular) life type that is out there practically all around the world's environment, and it is easier as compared to cells of creatures, fungi, and flowers. Of approximately three million types of micro-organisms considered to occur, just about 4,000 tend to be understood as they are divided into five general groups relating to their particular shape: bacilli (rod shaped), cocci (ball shaped), filamentous (bond like), spirilla or spirochetes (spiral shaped), and vibrio (comma formed). Some are free-living, safe or useful (also important) to other life forms, other individuals tend to be parasitic and create toxins that cause condition or death.
single-celled or noncellular spherical or spiral or rod-shaped organisms that reproduce by fission; essential as pathogens as well as for biochemical properties. Might free-living, saprophytic, or pathogenic in flowers or pets.
(pl. ) of Bacterium
Beyerinck and Jegunow have shown that some partially anaerobic sulphur bacteria can only exist in strata at a certain depth below the level of quiet waters where SH 2 is being set free below by the bacterial decompositions of vegetable mud and rises to meet the atmospheric oxygen coming down from above, and that this zone of physiological activity rises and falls with the variations of partial pressure of the gases due to the rate of evolution of the SH 2.
