orthomyxovirus, n. Virol.
Brit. |ˌɔːθəʊˈmɪksəʊˌvʌɪrəs|, U.S. |ˌɔrθoʊˈmɪksoʊˌvaɪrəs|
[‹ ortho- comb. form + myxovirus n. Compare earlier paramyxovirus n.]
Any member of a group (originally the genus Orthomyxovirus, now the family Orthomyxoviridae) of enveloped, single-stranded RNA viruses which have a segmented genome and two types of glycoprotein (haemagglutinin and neuraminidase) projecting from the envelope, and which include the influenza viruses. Also (in form Orthomyxovirus): the (former) genus itself.
In addition to the influenza viruses, the family Orthomyxoviridae now includes the genera Thogotovirus (containing tick-borne vertebrate viruses) and Isavirus (containing only the infectious salmon anaemia virus).

Pereira Viruses of Vertebrates (ed. 3) ix. 205 ‘Orthomyxovirus’ has been adopted as a generic name to include influenza virus types A, B and possibly C. 1975Dev. Biol.

Taussig Processes in Pathol. & Microbiol. (ed. 2) ii. 218 Another feature unique to some RNA viruses (reoviruses, bunyaviruses, orthomyxoviruses) is that the genome consists of several fragments or segments of RNA. 2001Avian Dis. 45 366 The number of basic residues around the cleavage recognition site does not appear to correlate with..increased virulence as it does with envelope glycoproteins in orthomyxoviruses and paramyxoviruses. |
