Genus: Tremovirus
Family: Picornaviridae
Genus: Tremovirus
Distinguishing features
The genus is distinguished on the basis of genetic characters. Avian encephalomyelitis virus (AEV) is most similar to hepatitis A virus (HAV, genus Hepatovirus), but differs by possessing i) a type IV IRES (HAV is type III), ii) 2A with an H-box/NC motif, and iii) 2B and 3A polypeptides with little sequence identity to the HAV counterparts.
