1962Adv. Virus Res. IX. 296 At a meeting of the Virus Subcommittee of the International Nomenclature Committee, held in Montreal in August 1962, the following decisions were made: (1) The proposed name nanivirus is to be replaced by Picornavirus. 1963Internat. Bull. Bacteriol. Nomencl. & Taxon. XIII. 218 It was agreed that a name was needed for the small ether-resistant RNA viruses of which enteroviruses form an important part. The name ‘Nanivirus’..was discarded in favour of ‘Picornavirus’. The prefix Pico- implies very small size, and RNA of course indicates nucleic-acid composition. (The initial letters of Picornavirus may be taken to refer to Poliomyelitis, insensitivity to ether, Coxsackie, orphan and Rhinovirus.) 1974L. Levintow in Fraenkel-Conrat & Wagner Comprehensive Virology II. iii. 154 Picornaviruses are the agents of a number of other important diseases of man and animals which remain to be controlled, including the common cold. 1976Fenner & White Med. Virology (ed. 2) xviii. 333 There are no antigenic relationships between most of the picornaviruses. |
