Subfamily: Zealarterivirinae

Genus: Kappaarterivirus

Distinguishing features

Kappaarterivirus wobum is the only species in the family. There is, however, considerable variability between available wobbly possum disease virus (WPDV) sequences isolated in New Zealand and Australia (70 to 80% identity at the amino acid level within the conserved RNA-directed RNA polymerase (RdRp) protein) and hence, these may be split into separate species in the future. 

Family: Arteriviridae

Subfamily: Zealarterivirinae

Subfamily: Variarterivirinae

Genus: Nuarterivirus

Distinguishing features

Members of this genus form a clade upon phylogenetic analysis (Figure 3. Arteriviridae). 

Virion

See discussion under family description. 

Subfamily: Variarterivirinae

Genus: Gammaarterivirus

Distinguishing features

Members of this genus infect mice and typically cause lifelong persistent infections without obvious symptoms. One isolate of lactate dehydrogenase-elevating virus (LDV C) has been associated with neurological disease in the C58 mouse strain.

Subfamily: Variarterivirinae

Genus: Betaarterivirus

Distinguishing features

Betaarteriviruses infect pigs

Virion

See discussion under family description. 

Family: Arteriviridae

Subfamily: Variarterivirinae

Distinguishing features

Members of this subfamily form a clade upon phylogenetic analysis (Figure 3. Arteriviridae). They encode an nsp2 protein that is considerably larger than its counterparts in viruses of other subfamilies, mostly due to the hypervariable region flanked by PLP2 and TM1.
