Los orthomyxovirus (ortho: para diferenciarlos de los paramyxovirus; myxo: por su afinidad por las mucinas o glicoproteinas de la superficie de las celulas afectadas) presentan un genoma RNA fragmentado (ocho fragmentos), de cadena sencilla lineal, simetria helicoidal, de polaridad negativa y miden de 80 a 120 nm de diametro.
The Mx protein is one of the best studied determinants of innate immunity and is considered to be involved in resistant activity to orthomyxovirus infection and has been found in many organisms including yeast (Rothman et al., 1990) and many vertebrates (Staeheli et al., 1989; Staeheli, 1990; Pavlovic and Staeheli, 1991; Bazzigher et al., 1993; Plant and Thune, 2004).
Influenza is caused by infection with influenza types A or B, which are RNA viruses of the orthomyxovirus family.
This study determined the pathogenicity of WFBV, a novel orthomyxovirus in the genus Quaranjavirus, in common eiders by observing clinical progression and pathologic changes in experimentally inoculated eider ducklings over a 10-day period.
