Picornaviridae
n one of the major ribonucleic acid virus families, to which the polio-, rhino-, entero-, and hepatitis A viruses belong. Viruses in this family have a single-stranded, nonsegmented, linear molecular structure with icosahedral symmetry.
Picornaviridae
a family of small (25 nm diameter), nonenveloped single-stranded, plus sense RNA viruses, the members of which cause a variety of diseases including poliomyelitis of humans (genus Enterovirus), respiratory disease in cattle (Rhinovirus), encephalomyocarditis in pigs (Cardiovirus), foot-and-mouth disease and equine rhinitis A (genus Aphthovirus), porcine encephalomyelitis (genus Teschovirus), avian encephalomyelitis and hepatitis A of humans (genus Hepatovirus) and equine rhinitis B viruses (genus Erbovirus).
