The range of organisms responsible for plant disease is vast and extends from the higher plants themselves, the parasitic angiosperms, to submicroscopic segments of naked RNA, the viroids. Between these extremes of size, one may find plant pathogenic organisms among the fungi, nematodes, protozoa, ...

virulence,virulency- extreme harmfulness (as the capacity of a microorganism to cause disease); "the virulence of the plague" transmitter,vector- any agent (person or animal or microorganism) that carries and transmits a disease; "mosquitos are vectors of malaria and yellow fever"; "fleas are ...
What are disease-causing agents called? Disease-causing agents are microorganisms or macro-organisms that, when infecting a host, result in disease. It is important to note that not all microorganisms and macro-organisms are disease-causing agents. This is because many of them (even when infectin...
Note that, because viruses require host cells in order to replicate, many scientists do not consider viruses to be alive (and hence they are not considered to be organisms). Despite that, because viruses are small and many cause disease, they a...
plant pathology is A、the study of the organisms and environmental factors that cause diseases in human, mechanisms by which they cause disease, and methods of managing diseases and reducing damage. B、the study of the organisms and environm
Silver nanoparticles are the most studied nanoantibacterial agent. In contrast to antibiotics that generally act through one mechanism only (Antony et al. 2013), Ag-NPs act against disease-causing bacteria through multiple mechanisms, enabling them to overcome bacterial resistance (Knetsch and Koole 20...
We need to know that not all bacteria are in connection with illness. Just some bacteria can cause disease. They are called pathogenic bacteria. Fortunately our immune system can protect us from them. Bacteria are prokaryotes ( single cells that do not contain a nucleus). It may seem weird ...
Researchers find traces of disease in dolphin poop: A potential tool for live health monitoring Scientists have found a new non-invasive way to identify a deadly virus in dolphins that could be a testing breakthrough. For the first time, researchers at the University of Hawai'i Health and Str...
2. Subsystems are inter-dependent and failure of one subsystem will on average increase the failure-risk of other subsystems 3. Certain combinations of subsystem failures cause death of the entire organism. There may be many different combinations of subsystem failures that lead to death—reflecting...
