单词	virino
释义	virino /vɪˈriːnəʊ / noun (plural virinos) Microbiology A hypothetical infectious particle postulated as the cause of scrapie, BSE, and CJD, consisting of non-coding nucleic acid in a protective coat made from host cell proteins. Compare with prion2.Some scientists claim that because there are many types of TSE agent, the virino is a more likely explanation.... Taxonomically this places virinos between conventional viruses and viroids (a class of plant pathogens which neither need nor code for proteins to be infectious). In support of the virino hypothesis is the existence of different strains of prions that cause differing patterns of disease and breed true; the existence of strains in pathogens is usually the result of changes in the nucleic acid sequence of the infectious agent. Origin 1970s: from virus + the diminutive suffix -ino.
