orbivirus Biol.|ˈɔːbɪvaɪərəs|
[f. L. orbis ring, circle (see quot. 1971) + virus.]
Any of a group of arthropod-borne RNA viruses which cause disease chiefly in higher animals and are similar to reoviruses.
1971E. C. Borden et al. in Jrnl. Gen. Virol. XIII. 269 The authors suggest as a name for the distinctive group of viruses described, orbiviruses (from orbis, (L.), ring or circle). This name reflects the especially large, doughnut-shaped capsomeres seen on the surface of virus particles in negative contrast preparations. It is proposed as a ‘genus’ name, equal in hierarchy to reoviruses. 1974W. K. Joklik in Fraenkel-Conrat & Wagner Comprehensive Virology II. v. 236 Since very few orbiviruses have yet been characterized with respect to the structure of their RNA or the polypeptide constitution of their capsids, and since they are serologically very diverse.., the principal criterion for admission to this genus is morphology. Ibid., Although only few orbiviruses have been isolated from vertebrates, antibodies to them are widely distributed. 1976Fenner & White Med. Virol. (ed. 2) xxii. 407 Colorado tick fever virus is the only orbivirus so far recognized as a human pathogen. |
