Genus: Potamipivirus


Genus: Potamipivirus

Distinguishing features

The genus is distinguished on the basis of genetic characters.

Virion

Morphology

No surface morphology of the icosahedral capsid is visible by EM. 

Nucleic acid

Genome (Fichtner et al., 2013): c. 7,496 nt (partial) (5′-UTR: >488 nt; ORF: 6,777 nt; 3′-UTR: 231 nt). The location of the cre has not been identified.

Genome organization and replication

Genome layout:

VPg+5′-UTR-[1AB-1C-1D-2A1npgp/2A2H-box/NC-2B-2C/3A-3B-3C-3D]-3′-UTR-poly(A)

The deduced polyprotein is of 2,259 aa. There is no L protein. 1AB protein remains uncleaved. 2A1 protein has a NPG↓P motif. 2A2 protein has a H-box/NC sequence motif.

Antigenicity

See discussion under family description.

Biology

Eel picornavirus (EPV) was isolated from a common eel (Anguilla anguilla) in Lake Constance on the river Rhine. EPV can be propagated in eel kidney 1 (EK-1) cells. It is pathogenic in experimentally infected glass eels and induces a high mortality.

Species demarcation criteria
