A、An organism upon which an organism of a different species grows and from which all or most of its food is derived. B、an organism that causes disease. C、A saclike structure, usually containing eight ascospores or the sexual spores of the Ascomycota, formed by karyogamy and meiosis. ...
Parasiteis A、an organism that grows part or all of the time on or within another organism of a different species(known as its host),and from which it derives all or part of its food. B、an organism that lives on dead organic matter. C、

While the aggressive nature of these species threatens horses and prohibits optimum pasture and range utilization, a greater threat is the risk to sensitive or threatened native plant species and the balance of plant biodiversity. Though the putative toxin causing the neurological disease in horses ...
The ability to image adoptively transferred T cells in the body and to eliminate them to avoid toxicity will be vital for chimeric antigen receptor (CAR) T cell therapy, particularly against solid tumors with higher risk of off-tumor toxicity. Previously
[46]. While the possible role of Epstein-Barr virus in causing retinal disease is controversial, as it can often be detected in non-infectious uveitis, it is strongly associated with nasopharyngeal cancer and lymphomas that can invade ocular tissues [47,48]. Similarly, human herpesvirus-8 is ...
According to the endosymbiosis hypothesis, mitochondria are derived from the ancestor of α-proteobacteria. This endosymbiont steadily lost its autonomy as it became integrated into the host and then evolved into organelles [57,58]. As the phenomenon of intercellular mitochondrial transfer is revealed,...
(cellular colonies which outlive the organism, such as hair and fingernails, remain uninfected). Once infected, the host’s dead cells undergo a radical transformation. The cells are effectively reanimated, although they are so altered that it would be inaccurate to describe the host organism as...
While a breakdown in the host immune system may lead to commensal organisms causing disease, bacteria have evolved a number of mechanisms to enhance their disease-causing potential, and allow them to evade the immune system. Resistance to lysis by serum is a feature of the Enterobacteriaceae, ass...
Interferons, which can be produced by any mammalian cell, are involved in the rapid and efficient host innate response against viruses. A powerful IFN response triggered by the first contact with a virus can slow down viral multiplication and “buy time” for the organism to establish a more ...
