leukovirus Virology.|ˈl(j)uːkəʊvaɪrəs|
Also leuco-.
[f. leuko- (in leukæmia and leukosis, leucosis) + virus.]
Any of a group of pleomorphic viruses consisting of enveloped single-stranded RNA, different members of which cause leucosis or tumours in mammals and birds.
1968F. Fenner Biol. Animal Viruses I. i. 26 The viruses which are associated with leukosis of chickens and murine leukemia have as their genetic material a molecule of single-stranded RNA of about 12 million daltons atomic weight. The pathogenic potential of both groups of agents is similar, as are the virions. These viruses can therefore be grouped together into a new group, for which we propose the name ‘leukovirus’. Ibid. 28 Most infections with leukoviruses are latent for prolonged periods, but they may eventually cause fatal disease, usually apparent as a disturbance of the lymphoid or hemopoietic systems. 1970Nature 14 Nov. 622/1 The RNA tumour viruses (leucoviruses) seem to have a different mode of replication from other RNA-containing viruses. 1971Maramorosch & Kurstak Compar. Virol. xvi. 514 The more euphonious term leukovirus suggested by Fenner (1968) has recently been approved by the International Commission for the Nomenclature of Viruses and will be used here. 1972Sci. Amer. Jan. 25/3 A group of viruses, variously called the RNA tumor viruses, the leukoviruses or the rousviruses.., replicate by another mode of information transfer. |
