Viruses aren't alive; they can only grow and reproduce inside of the host cells they infect. Bacteria are living organisms. Both viruses and bacteria can get you very sick, but most bacteria are harmless and many are helpful.
The expression of many bacterial phenotypes is regulated according to the concentration of chemical cues that they or other bacteria produce, a process often termed quorum sensing (QS). Many aspects of the environment can affect cue concentration. Thus these molecules might be indirect proxies for ...
Silencing the mob: disrupting quorum sensing as a means to fight plant disease Bacteria are able to sense their population's density through a cell–cell communication system, termed ‘quorum sensing’ (QS). This system regulates gene... Y Helman,L Chernin - 《Molecular Plant Pathology》 被引...
Quorum sensing and the cell-cell communication dependent regulation of gene expression in pathogenic and non-pathogenic bacteria Although it has been clear for some time that individual bacterial cells employ intra-cellular signalling systems to sense, integrate and process informati...

Quorum Sensing: How Bacteria Communicate,by Bonnie Bassler Bacteria can communicate, and they speak multiple languages! Bacteria use chemicals as their “words.” They use chemical communication to distinguish their own species from others, and in doing so, presumably reveal friend from foe. ...
rapidly multiply, consuming resources, triggering immune responses, and generating toxins that harm the host.2 When enough planktonic bacteria attach to a surface, whether it be the surface of a wound, an implant, or a body cavity, a phenomenon called quorum sensing triggers a change in ...
Unicellular organisms such as bacteria can use a type of cell signaling called quorum sensing to detect their concentration in a colony and generate coordinated responses. Eukaryotic cells can release ligands that target the same cell that produced the signal (autocrine signaling) or...
What's in a name? The semantics of quorum sensing The expression of many bacterial phenotypes is regulated according to the concentration of chemical cues that they or other bacteria produce, a process often termed quorum sensing (QS). Many aspects of the environment can affect cue conc... TG...

which lives in shallow waters,also has a symbiotic relationshipwith a bioluminescent bacterium,Aliivibrio fischeri. At night, these bacteria begin to glow, and the squid uses their light to camouflage itself against the night sky. This counter-illumination strategy is akin to an invisibility cloak....
